The colonists had adopted their architectural styles in building modified to the climate context (warm and humid climate). These colonial buildings in Malaysia also have combinations of the styles from other cultures such as Indian and Chinese due to migrations and from the local Malay traditions. This paper will discuss about the development of architectural styles that have been experienced in Malaysia since the colonial era. These unique architectural styles and motifs have heritage values, many of which are being conserved until today. Apart from that, we will also look into their influences in a smaller scale as well as in a larger scale – as this has formed an identity for Malaysia's architecture. We have been arguing for some time about the true identity that represents Malaysia's architecture, and this matter has recently become a main factor to consider when deciding the style of architectural decorations to be integrated into building design. On the contrary, there is also an urgent need to develop new appropriate design linked with the past and present. A synchronised awareness by both the architects and the planners of the historical and cultural perspective of a place and its architectural precedence provides a firmer basis in the pursuit to relate new designs with the local technology and sosio-economic development.
