==Abstract==

This paper describes a landmark membrane structure where the surface
appearance has been able to be maintained after years in service. The membrane structure 
is the main canopy structure located at the courtyard of Islamic Complex, Putrajaya, 
Malaysia. It is made using PTFE membrane which is known for its excellent durability. The 
construction process of the main canopy together with the mini canopy which consists of a 
group of four funnel-shape membrane structure made using PVDF membrane will be 
presented in this paper. The paper will also touch on the performance of PTFE membrane in 
humid tropical weather condition like Malaysia.
