These buildings look pretty spectacular, and also cool themselves, without any A/C. Permaculture is about sustainability, which also includes sustainable building

Along with the rapid modernization, came rapid change of mainstream perceptions. Bamboo is now commonly viewed as being "wood for the poor" according to Mr. Ramadan, but this perception is starting to change and it is Mr. Ramadan’s mission to help accelerate that change.
Before 2008, Mr. Ramadan had absolutely no experience with building anything, much less structures made out of bamboo. A chance meeting with a builder from Indonesia changed that and Mr. Ramadan hired the builder to construct a house on his land in a still relatively underdeveloped area outside of Kuala Lumpur named Hulu Langat.
Mr. Ramadan immersed himself in the project and worked alongside the builder and his team and learned how to build with bamboo — enough that on the second phase of his design he went solo and recruited international volunteers, affectionately known as WWOOFers, to help him build the structures. He also made innovations to the traditional Indonesian methods and incorporated modern and novel elements into his structures."
