ABSTRACT
One of the most studied areas for increasing interior design performance is kitchen.
The reason for this is the expectation of a superior performance from kitchen as
regards numerous criteria compared to other areas. When scientific studies
conducted on kitchen design performance were examined, it was observed that they
are basically divided into two groups. The first group consists of those related to
performance of industrial kitchen products. The works carried out in the other group
describe the basic design rules to increase kitchen design performance. However, a
study examining the effects of any kitchen design rule on kitchen functionality in a
comparative way was not found in all the resources obtained. Accordingly, the
objective of the study has been described as determining the effect of each design rule
utilized for improving the kitchen design performance on the functionality of the
kitchen. To this end, a literature research was conducted as the methodology of the
study at the first stage and a set of rules was created for kitchen design. Subsequently,
effect of each design rule on the functionality of kitchen was determined with
designers of a company which has 60 dealers in Turkey and which produces and
markets kitchen systems. Personal interview method, which is a statistical data
obtaining tool, was conducted with focused groups while this was performed and in-
depth interviews were carried out with relevant people.

INTRODUCTION
The complex cognitive activities forming the basis of design have led people to question a
measurable parameter such as "performance". The relation between these two basic
components has begun to be examined particularly due to Louis Sullivan's "form follows
function" approach. Accordingly, methods have been researched through both scholars and
practitioners for enhancing the design performance and various approaches have been
proposed (Kalay, 1999; Sullivan, 1934). Furthermore, Design Quality Indicator (DQI)
developed through the Construction Industry Council (CIC) in the U.K. has begun to be
utilized as a measurement tool to assess design quality (Whyte and Gann, 2003). In this way,
it is possible to meet user needs at the optimum level and produce high-quality projects
(Oyedele and Thambi, 2007). The concept of "action system" which is called the performance
approach in architecture and interior design is an approach aiming to find the most functional
and economical solutions by taking into account the relation of the behaviors of the user at
different levels within space as regards the usage (building-section-space-action space-one
action) of the building (Arcan and Evci, 1992). In this context the real measure of interior
quality is user satisfaction and efficiency which is the final result thereof (Power et al., 2000).

One of the most studied areas for increasing interior design performance is kitchen. The
reason for this is the expectation of a superior performance therefrom as regards numerous
criteria compared to other areas (Yazıcıoğlu and Kanoğlu, 2016). It has been determined in
the researchers conducted that average 30% of the works done in the house consist of food
preparation and actions related to it (Arcan and Evci, 1992; Thiersch, 1977). 360 actions
different from each other are performed in the kitchen in average during a day and a kitchen
is used for 20 years. In this case, 2.6 million actions independent from each other are
performed in the same kitchen during the usage period thereof (Blum, 2013). Moreover, the
space which is most desired to be renewed in a house has been found to be the kitchen with
the rate of 34% as a result of a survey conducted in 2009 as shown in Figure 2 (Harbor,
2009).
Figure 1. The Rates of Demand As to Renewal of Spaces Within A House (Harbor, 2009)
In addition to all these, kitchen is the area for a designer which has to be resolved almost in
all projects. As such, different than other places, researches made for increasing the kitchen
interior design performance dates back to much earlier times such as the 18th and 19th
centuries. For example, in a research made in 1850 by the U.S. Dept of Agriculture it has
been revealed that adapting the bench height according to ergonomic measurements of each
user can improve the design performance of kitchen. In 1912, Christine Fredericks conducted
a research named "string study” related to the placement of kitchen cabinets and devices. Her
works have revealed the fact that creation of correct distance between the kitchen cabinets
and devices have great importance both in terms of the energy spent and time.
MargareteSchütte-Lihotzky, a Viennese architect, has developed the Frankfurt kitchen in
1926 with a similar approach. Schütte-Lihotzky and architect Ernst May have worked
together with an eye to develop an advanced house construction program in order to create
alternatives to better design the living spaces in a house. To this end, different actions and
movements in the kitchen were assessed by making measurements and the results are used as
auxiliary data in the design of kitchens. The kitchen projects obtained in this way were used
in more than 10,000 houses. After the Second World War, this kitchen model became an
architectural standard both in the U.S. and Europe due to its having high design performance.
In 1927, Architect A. Schneck conducted a study for the design of required storage space in
the kitchen. According to his opinion preparation of a list of objects of a small house to be
stored is the starting point of the right kitchen design (Dynamic Space, 2016). The School of
Architecture of the University of Illinois has developed a model in 1940 for increasing the
kitchen's design performance. According to this model, the main operating functions in the
kitchen take place between the oven, kitchen sink and refrigerator. This triangle formed
between these imaginary activity areas was named as "activity triangle". The main idea is that
Kitchen
34%
Bathroom
8%
Bedroom
26%
Living Room
28%
Other
4%

it will be possible to work in the kitchen in an effective manner if these three points are in
optimal proximity to each other. This rule is not applicable geometrically for a kitchen with a
single wall. However, also in these types of kitchens it has been proven that the distance
between these three areas of activity to each other is the most important factor which affects
the functionality of the kitchen (Wikipedia, 2013; Illinois University, 2015).
Numerous researches are carried out to increase kitchen design performance in our day in the
light of the researches conducted in the 18th and 19th centuries. For example, the research of
Morishita et al.(2003) based on the principles of the U.S. Dept. of Agriculture's research
carried out in 1850 to enhance kitchen design performance an electronic system which
adjusts automatically the height of kitchen bench according to changing actions according to
the cooking actions of the user while has been proposed.
When other scientific studies conducted on kitchen design performance were examined
within this context (Pal and Rehman, 2008; DemirkanveOlguntürk, 2013; Cline, 2006; Rivet,
2009; Mak and Francis, 2002; Panwar, 2009; Lamkins, 2011; O'Heir, 2007; Stander et al.,

2003; Mielke, 2005; Rand and Perchuk, 1991), it was observed that they are basically divided
into two groups. The first group consists of those related to performance of industrial kitchen
products. The works carried out in the other group describes the basic design rules to increase
kitchen design performance (Yazıcıoğlu, 2014a; Yazıcıoğlu, 2014b; Yazıcıoğlu, 2014c;
Yazıcıoğlu and Kanoğlu, 2016). However, a study examining “the effects of any kitchen
design rule for enhancing the kitchen design performance on kitchen functionality” was not
found in all the resources obtained. However, existence such a comparison will be an
important tool showing the way to a designer for enhancing the kitchen design performance
during the design process.
PURPOSE AND METHODOLOGY
The objective of the study has been described as determining the effect of each design rule
utilized for improving the kitchen design performance on the functionality of the kitchen. In
line with this objective, a literature research will be conducted as the methodology of the
study at the first stage and a set of rules will be created for kitchen design. Subsequently,
effect of each design rule on the functionality of kitchen will be determined with designers of
a company which has 57 dealers in Turkey and which produces and markets kitchen systems.
Personal interview method, which is a statistical data obtaining tool, will be conducted with
focused groups while this is performed and in-depth interviews will be carried out with
relevant people.
FORMATION OF SET OF DESIGN RULES FOR INCREASING THE KITCHEN
DESIGN SUCCESS

DETERMINATION THE EFFECT OF EACH DESIGN RULE ON KITCHEN’S
FUNCTIONALITY
The design rules related to people with disabilities were excluded priorly from the set of all
design rules in order to determine the effect of each design rule on functionality of kitchen in
a healthy way (Table 1). The reason for doing this is to define design criteria for users who
have similar needs in projecting the kitchen correctly in terms of design performance
(Demirkan and Olguntürk, 2013).
Table 1. Kitchen Design Rules For Physically Disabled People
No
Design Rules
R52
The maximum height for someone sitting in a wheelchair in front of a
counter with 51cm-64cm depth to be accessed is 112cm. If there is not such
a counter the access distance is between 38cm and 122cm.
R58
The knee space must be spared in every possible part of the kitchen sink,
oven and range such as the bottom part or immediately next to it. The knee
space must be at least 69cm high, 76cm wide and 48cm deep. Height of
69cm can be reduced depending on the increasing of the depth.
R59
The kitchen sink must be fixed lower than 86cm or its height must be
adjustable between 74cm and 91cm. The hole of the kitchen sink must not
be deeper than 17cm. There must not be a surface with sharp or rough end
under the kitchen sink. A knee space must be planned for wheelchair users
under the kitchen sink. This knee space must be 91cm in width, 69cm in
height and with 20cm depth. If the distance is 43cm in depth, a space with
23cm height from the ground must be left for the toes.
R63
At least an area with 152cm diameter including knees and toe space must be
allocated so that the wheelchair can rotate.
R64
There must be a T-shaped empty floor space floor space with a body length
of minimum of 91cm and with arms with a total length of 152cm on both
sides of the body in equal length so that a wheelchair rotation area is
functional.
R91
A knee space must be created at the bottom of a device oven upper surface
of which is 86cm-71cm height above the floor.
Personal interview method, which is a statistical data obtaining tool, was conducted with
focused groups while this was performed and in-depth interviews were carried out with
relevant people in order to determine the effect of each design rule (except the rules in Table
1 for physically disabled users) on the functionality of kitchen with designers of a company
which has 57 dealers in Turkey and which produces and markets kitchen systems. This tool
was preferred due to its being a superior technique in learning the knowledge and ideas of
people on the relevant subject and what may be causing the creation of these thoughts. The
group method, among the personal interview methods, was selected in this
study. Accordingly, the company‟s design team members answered the questions in a
connected way with each other and with interaction with each other. The people listened to
the opinions of others while stating their opinions and created new ideas thanks to this

The groups of design rules prepared according to Figure 2 is as shown in Figure 3.
Figure 3.The Groups of Design Rules Prepared According to Grades Received
When the results in Figure 3 were evaluated it was found that creation of the activity triangle
correctly, convenient access to storage spaces and devices vertically and horizontally, empty
kitchen bench spaces which have to been on both sides of the kitchen sink and the oven and
proper lighting of the kitchen according to actions are the first and foremost important design
rules affecting the kitchen's design performance. The second equally important design rules
are described as empty spaces for circulation which should be left mainly in the front of the
devices, positions of the dishwasher and the kitchen sink and their relations with each other.
Third degree important design rules include rules as to dimensions of the kitchen bench and
storage units in the area of washing activity. The fourth degree important design rules are
incident to the service areas which mainly have to be located near the devices. The fifth
degree important design rules consist of information regarding the dimensions of the kitchen
entrance and circulation areas and how storage areas in the entire kitchen should be designed.
Other less important design rules cover mainly issues as to two or more people‟s being able
to cook in the kitchen at the same time, design of the eating and food-service areas and
security in the kitchen.
RESULTS
The basic rules to be observed to enhance the kitchen design performance and data analysis
chart revealing the degree of impact of these rules on the functionality of the kitchen in a
comparative way were prepared in this study. The designer can enhance the kitchen interior
kitchen design process in a more conscious way by using the foregoing information which
will lead to making the right decisions in accordance with needs of users, producing practical
solutions and creating activity areas with "high efficiency".

... For example, there is a well-known rule of thumb "kitchen triangle". The idea was proposed by the School of Architecture of the University of Illinois based on the importance of reducing travel distances between different stations and other points in a kitchen thereby increasing efficiency (Yazıcıoglu & Kanoglu, 2016). Also (Shimmura, Fujii, & Kaihara, 2017) show that a well-designed kitchen can lessen the burden on kitchen staff and optimize their performance. ...
... Item information is given in the Appendix. A 6-item scale based on the literature (Shimmura et al., 2017;Yazıcıoglu & Kanoglu, 2016) was used to measure spatial efficiency (SE). The information resources (IR) scale has 6 items based on the literature (Ceylan et al., 2008;Yeh & Huan, 2017). ...
... First, PAF appears to be a more significant mediator than SD. For studies of creativity, some focused more on the functional component (Voigt, Bergener, & Becker, 2013;Yazıcıoglu & Kanoglu, 2016) while others leaned toward the social element (Teo, Bentley, & Nguyen, 2020;Wardono, Hibino, & Koyama, 2012;Xie, Peng, & Huan, 2014). The inclusion of both factors in the same study allows the comparison of their relative importance in a particular context. ...

This study examines the effect of the physical environment on the social dynamics of employees and their perception of resource adequacy, which eventually leads to their creative performance. The subjects are kitchen employees who are regularly required to invent new dishes to offer restaurant customers so there is a sense of novelty. Data were collected from 425 kitchen employees who worked in ten Taiwanese restaurants. The study uses AMOS to perform structural equation modeling to analyze the data. The results show that the physical environment's functionality does not affect employees' social dynamics. However, spatial efficiency does. This study provides evidence that differences in the physical environment change the perceived adequacy of facilities and social dynamics and affect creativity.

In this research, it is intended to determine modes of use for undersink cabinets located in house kitchens and to determine the needs required in this volume of space. For this purpose 50 house kitchen undersink cabinets have been photographed while they are being used and materials-objects contained in them have been determined in Türkiye. In conclusion it has been determined that contained in the undersink cabinet are cleaning supplies (cleaning chemicals, bleach, vinegar, dish soap, cleaning bucket, etc.), foodstuff (oil, jarred food, food in plastic bags, etc.), small appliances and tools (oven-stove with single burner, toaster, small-large propane bottle, etc.), various utensils (plastic containers, pots, frying pans, trays, teapots, etc.), kitchen waste bin and water filtration appliance to varying extents. Of the undersink cabinets we examined, 40% has a single shelf within and 60% has no shelves. It was observed that due to careless design of the under-sink cabinets and failure to plan for the requirements, layouts are untidy and it was determined that the users use certain items such as cabinet door baskets, in-cabinet organizers, etc. in order to cope with this untidy layouts. Given the facts that oil and such materials as bleach etc. which stand side by side in the cabinet may react with each other in case of toppling or leakage, it might be suggested that such volumes must be planned very carefully and that users must be very careful against poisoning.
... There are several studies that analyze daily user activity in residential spaces. It has been shown that on average 30% of activities in the home are subordinated to the food preparation, and that 360 different actions are performed in the kitchen during the day [33]. Elderly people often have physical limitations, alongside the cognitive ones, so reducing movement and preparing the conditions for efficient use of the kitchen workspace is very important. ...
... Additionally, the kitchen has been identified as the most desirable space for renovation, both aesthetically and technically. According to [33], 34% of people prefer to renovate their kitchen before the other areas in the home. To the best of our knowledge, current research related to AAL did not take into account the dimensional analysis and design of the existing kitchens, as well as the possibility of considering the whole process of the food preparation and sensor position. ...

Numerous researchers are working on Ambient Assisted Living systems to enable more comfortable and safer living for senior people in their homes. Due to modern lifestyles and an aging population, this has become a very important issue. According to the available literature, it is obvious that the kitchen is one of the most important and most dangerous rooms in the home. However, there is still evident lack of monitoring systems suitable for specific kitchen activities. In this paper, we propose a monitoring system capable of identifying activities related to the cooking process, and a decision-making system capable of identifying some unwanted and possibly critical conditions. The proposed systems are designed to satisfy the requirements of the modern Ambient Assisted Living systems dedicated to older adults. The proposed monitoring system consists of ultrasound, temperature, and humidity sensors. The acquired results from these sensors are the inputs for the decision-making system, which generate warnings or alarms intended for the senior users and/or formal or informal caregivers. This system is designed to improve home safety related to kitchen activities, as well as to provide information about the lifestyle and daily activities of senior users. Experimental validation of the proposed system confirms its functionality and accurate design approach.
... SIMURG proposes using different sets of KPIs for all entities in each dimension of the Cartesian system in addition to a certification system of these entities at all levels of these dimensions, without an exception. A comprehensive model, SIMURG_MORPHO_BLUE developed as one of the sub-projects of SIMURG by Yazicioglu and Kanoglu [35][36][37][38][39][40] for the assessment of the architectural design of kitchen premises, can be given as an example of "03_premises" level assessment model. It proposes a certification and accreditation system of premises-level entities in the built environment and also suggests how such a system should be organised. ...

Sustainability assessment is one of the basic issues in the agenda of public authorities and it requires practical tools to measure performance in terms of sustainable development goals. Most studies in the literature deal with only one dimension of the problem of environmental components of sustainability. These studies discuss entities at only one level (cities, buildings, etc.), and one layer (green, smart, etc.) in selected dimensions. The literature includes no models that claim to provide an integrated assessment of entities' performance in the 3D Cartesian system. The presently available models do not offer solutions that would be applicable in practice. SIMURG (A performance-based and Sustainability-Oriented Integration Model Using Relational database architecture to increase Global competitiveness of construction industry) proposes using layers and their KPI sets in the assessment process. In addition to philosophical, organizational, integrational, and computational models, this study aims to develop a lean architecture of a relational database model by eliminating ineffective solutions in the practical dimension, i.e. in the computer model. The model can be used by individuals to help them choose a built environment whose characteristics match their expectations. Public authorities can utilize the model to increase the level of accountability, transparency, and legitimacy in their decision-making processes.

Kitchen is the heart of a house. Since major part of time is spent in kitchen compared to other areas in the house, it needs to be designed with utmost care. Attention needs to be paid to the type of kitchen, work areas in kitchen i.e., preparation area, sink and cooking area. Storage facilities, openings and ventilation must be adequate so that home maker can do cooking with less strain. With this background, the present study has been conducted through case study method to evaluate the kitchen design in rural areas. The study was conducted in Dabliguda, Maheswaram Mandal in Telangana state. Observations were made in 10 kitchens to understand the existing kitchen conditions. It was found that all the kitchens were placed in the right direction i.e., east. Kitchen sizes also met with the standard specifications as minimum size was 90 sq. ft. and maximum size being more than 150 sq. ft. against 45 sq. ft. as the standard size. But the drawbacks observed in the rural kitchens were lack of adequate ventilation, absence of work triangle as only two working spaces are provided in most of the kitchens and very deep storage shelves. The study implies that rural families need to be educated about importance of implementing design standards for better health, comfort, convenience and to improve work efficiency.

This is an open-access conference paper distributed under the terms of the CC-BY-SA 4.0 Today decision-making processes of public authorities, who have the responsibility of developing sustainable policies for their built environment entities, do not support transparency, accountability, and consistency of their decisions. What societies require is a human-centric vision, a consistent philosophical/paradigmatic model that supports this vision, and the tools that increase the legitimacy of the whole decision-making process. The problem is the lack of these visions and tools that allow the citizens to meet their priorities in their lives with the identities of built environment entities and public authorities to accept/propose suitable projects by using “layers” such as historical/smart/ green/slow/safe, etc. Most of the studies in the literature deal with the sustainability assessmen tproblem at only one environmental dimension of sustainability without considering interactions among the dimensions of 3D Cartesian system and their levels. A paradigmatic model and frame model, which will be used as a guide for developing further conceptual and practical models must be developed from scratch. The conceptual and practical models can only be developed in an iterative process by considering the interactions among these components. In this study, a bottom-up approach in an iterative process was adopted and practiced in the development process of the relationships among the components to propose the above-stated parts of the model of the research.

Malaysia is known for its multicultural diversity, which is heavily influenced by the ancient Malay culture, indigenous peoples and the cultures of Malaysia's second main ethnics groups - the Chinese and Indian. For centuries, our cultures have blended to create Malaysia's diverse heritage. Sadly, Malaysians are slowly losing their ancient culture due to modernisation. One particular culture of Malaysia that is close to extinction is the Peranakan culture. The researcher found it vital to implement our cultural motif into product design, so she has come out with a freestanding kitchen with an influence of the Peranakan motif.

Numerous hypotheses in the literature claim that there must be some correlations among the attributes of different types of entities such as project, organization, decision makers, etc., and performance of other entities such as sectors, companies, projects, operations, individuals etc. Project procurement departments of construction companies seem to be one of the most important entities to be investigated for this matter since their performance is vital for the companies' survival. This study is currently being conducted as one of the sub-projects of the master project entitled "SIMURG: A performance-based and Sustainability-oriented Integration Model Using Relational database architecture to increase Global competitiveness of Turkish construction industry in industry 4.0 era. The master project was designed to include research and development of related models at all hierarchical levels of performance-based design and construction of built environment approach with open-ended approach in various sub-projects in three complementary areas, i.e., product, process and social dimensions. The hierarchical levels of first two dimensions are a. building components, b. building elements, c. building premises, d. buildings, e. projects, f. lands, g. quarters, h. settlements, i. counties and j. cities levels on product side and a. operations, b. projects, c. departments, d. firms, e. groups of firms, f. sectors, g. national economies, and h. global economy levels on process side. Entities/facts at social dimension do not have a hierarchical structure. Each levels need their own level-specific Key Performance Indicators (KPIs) and associated weights to be determined in addition to organisational, computational and computer models to be designed. In this study the conceptual and practical models of performance-based assessment system at departments level have been developed to solve above stated problem in "project procurement" context. The conceptual model developed in this PhD thesis for performance-based evaluation of the related department will be converted into a relational database model in the master project and will be enriched by additional functions and reports to be able to investigate the relationships among the entities of built environment, professional environment and social environment dimensions.

One of the most studied areas for increasing the performance of interior design is the kitchen. The reason for this is it’s being the most important area of work compared to other areas from which high performance in many criteria is expected such as functionality, durability and hygiene. As a result of the literature survey carried out within the purview of the study as to increasing the design performance it was found that scientific efforts for increasing the performance of kitchen design is divided into two groups. The first group consists of those germane to industrial kitchen products. Studies in the other group provide information as regards basic design rules for increasing the kitchen design performance. There was no study on establishing the relation between "basic design rules" and "user requirements" in a systematic way for increasing the kitchen design performance in these obtained resources. As such, the purpose of this study is establishment of a systematic classification in which a relational link between the design rules proposed for increasing the performance of kitchen design with user requirements in kitchen is created. The scope of the study is limited to only one of the user's requirements with an eye to reach more accurate results. In line with this identified scope and purpose, the methodology of the study is determined as which of the user requirements will be discussed in the first phase with the reasons thereof. Subsequently, a literature survey was conducted and the set of design rules for increasing the kitchen design success was created. A systematic classification in which the relational link has been established between the design rules and user requirements at the last phase.

The kitchen space is one of the most studied areas for increasing the interior design performance. This is because of; being the most important working area compared to other spaces and expected to show a superior performance in terms of many criteria. The scope and purpose of the study was identified as; to obtain the statistical data describing mathematical correlation between the kitchen layout and total floor area and to present the results belonging to these data in the manner of an analysis table that will help designer to decide correctly at the stage of determination of kitchen layout. Meanwhile at the beginning, a literature survey was conducted for determination of what all kitchen layouts are as the study methodology. Later based on these kitchen layouts, 1.309 kitchen projects were examined and statistical data were obtained belonging to each projects' total floor area and kitchen layout. At the last stage, data analysis table was created that will help designer to determine the kitchen layout by identifying mathematical correlations between these statistical data. Through this study, designer can see how mathematical correlation is available between kitchen layout and total floor area over the statistical results. This will also enable the realization of a high design performance project that will help to make a more correct decision in determination of kitchen layout.

A kitchen design with high performance can be achieved only by creating appropriate solutions in line with the requirements of the person(s) who will use the kitchen. User requirements are mainly divided into two groups as physical requirements and psycho-social requirements. One of the psycho-social requirements of users can be considered as aesthetic needs. When we consider aesthetic requirements in the design of the kitchen we see that the most important components are the countertop material and the cabinet door type and the visual harmony between them. The target and objective of this study in this context is to obtain the statistical data revealing which cabinet door type is used in combination with which countertop material in kitchen design and convert the results incident to such statistical data into a meaningful data analysis table that will help the designer to make the right decision in the choice of cabinet door type and the countertop material. The cabinet door types and the countertop materials which will be studied have been defined at the first stage as the methodology of this study within the purview of this defined scope and purpose with the grounds thereof. Subsequently, 1.309 actual kitchen projects have been examined in order to obtain statistical data showing the relationship between the countertop materials and the cabinet door types. In the final stage of the study the mathematical relationship between these statistical data obtained as a result of these examinations have been converted into a meaningful data analysis table.

Commercial kitchens consume a significant amount of energy in restaurants and other establishments having food service operations. The manufacturers are applying the products that reduce the exhaust rate which in turn reduces the required supply rate and the number of air exchanges per hour to promote energy efficiency. Proximity hoods hung in close proximity to the cooking appliances enable to reduce the net airflow through the space while maintaining the efficiency. Due to the closeness to the cooking surface these hoods have less vulnerability to cross drafts and can generally exhaust at lower exhaust rates. The other system is demand ventilation system which is based on the premise that cooking loads vary throughout the day. It monitors the cooking operation and adjusts the exhaust, supply, and rooftop unit fans so that when the cooking load is reduced, the fans operate at a reduced level thus saving energy. Electrically commutating motors use their internal circuitry to convert 115 V single-phase power to a controllable DC voltage results in increased efficiency.

The aim is to provide a priority-based ‘design for all’ approach list that can be used as a guide in the architectural design process for independent living of the home users. It is important to prioritize ‘design for all’ factors and their items as well as the significant differences among adults, elderly and adults with physical disability and visual impairments for the design of homes. A survey was conducted with 161 participants, including adults, elderly and adults with physical disabilities and visual impairments. The results of a factor analysis test identified six high-loaded (adequate illumination level, ease of use in kitchen, adequate space for approach and use, adequate contrast between essential information and its surroundings, ease of use in accessories and functional vertical circulation) and three low-loaded factors (provision of privacy and safety in bathroom, safety of floors and accessibility to all spaces). Multiple comparison tests were done in order to determine the group differences in each prioritized factor for diverse users. Furthermore, a priority-based list with the characteristic features of the ‘design for all’ approach for independent living is developed as a guide for home designers.

Universal design process is a multi-constraint task due to many user requirements and the complexities caused by the interaction of the requirements in developing design solutions. Since all universal design requirements cannot be equally satisfied, a designer must determine the relative importance and implementation order of each requirement. Prioritisation of requirements is needed, not just to ignore the least important but also to guide designers while coping with dependencies, conflicts and trade-offs between multi-attribute requirements simultaneously. Thus, this study proposes a priority-based approach for satisfying diverse users’ needs, capabilities and expectations in a design process conducted in a computer environment. The planning game technique and the analytic hierarchy process technique using a cost–value approach are the two techniques that are applied in prioritising the diverse requirements. The derived priority information is incorporated into a CAD interface with a developed plug-in tool. A universal kitchen design is chosen as a case study for the priority-based approach. The results of the acceptability studies indicate that the proposed plug-in tool is found useful, understandable, efficient, helpful and satisfactory in universal design process and can be developed for various architectural design applications.
