Bamboo at Bangkok Treehouse - Bangkok Tree House is a unique eco hotel on Phra Pradaeng Peninsula, an island in the Chao Phrya River, often called "Bangkok's Lung" for its lack of development and plentiful trees and orchards. Bangkok Tree House adheres to many green values. For one thing, bamboo is used for much of the building materials, partly because of its sustainability and its local abundance. Bamboo is also perfect building material and its strength and durability. Here it is used for floors, walls, ceilings. Solar cookers are used in the hotel's kitchen, along with solar hot water heaters. Everything from cleaning materials, to food in the cafe is all organic in keeping with the policy of the place.
