Hi Selena, certainly a very unusual request for SG! Are you looking for DIY advice, or looking for a builder to help you with constructing one?

hi, i dun think i can DIY it.. so i'm actually looking for a builder if the price is right..

Try using the "Find Professionals" category just below the search bar at the top! For example, you could do a search for "builders" like this: https://www.houzz.com.sg/professionals/c/singapore/s/builders Good luck with finding the right pro for this unique job!
