I recently bought a great book on Bahian architecture, which not only shows the homes of various architects but also the houses they have designed. One of the houses included is that of Caetano Veloso. If you are into tropically-inspired architecture, this book will definitely give you some great ideas. If you speak German or French, translations are included on each page.
“We have searched high and low for Bahia’s loveliest homes and spots, from typical fisherman’s huts to sophisticated modern homes. Highlights include a treehouse by sculptor and environmentalist Frans Krajeberg, a house made of corals owned by American actor Jamie Grange Stuart, an experimental house with a bamboo roof, and a house perched on a cliff built by artist Calazans.”
