I have been wanting to walk and see what the structure is. So I detoured on the way home today.
It has a translucent wavy roof and it is eye catching from a far.
I now know what it is. It's the Centre for Aquatic Science Research at Ulu Pandan. It's a research centre for Singapore-Delft Water Alliance. I have not heard of this before. If you want to find out more, you can visit their website at : http://www.sdwa.nus.edu.sg/
