Tour an early-20th-century traditional Malay wooden house that was found in the overgrown jungles of Perak, painstakingly disassembled and removed, and lovingly rebuilt and restored in KL. Badan Warisan is the nonprofit organization behind the project, and they accept donations in exchange for excellent guided tours of the house. Give yourself at least an hour and a half to tour the house -- longer if you'd like to view the video of how they did it.
