摘要:The paper presents the results of a study on internal design of Malaysian mosques froma typological way of research. Specifically it will look at the form and spatial varietywhich leads to the functionality of interior space. Orientation of mosques is taken intoserious consideration because the prostration activity for Muslims is performed whilefacing the 'qibla' towards the Ka'bah in Mecca, where the unity of the religion can beseen during the congregational prayers. Apart from that, this typoiogical research willalso show clearly the evolution of mosque architecture from the beginning of Islamicembracement in Malaysia. From there, classification of types of mosque design will bedefined by analyzing the inner spatial composition and not just by looking at the externalbuilt forms. As a result, it is hoped that this paper will help innovate design solutionsto the mosque designers and to Muslims who will be using the facility . The typologicalindex produced in this paper will help the present and future generation to learn historythrough the trend of mosques design evaluation that is shown in the classified images.
