The Bonsai tiny home is one of Bamboo Living's many homes that use timber-grade structural bamboo as a building material. These innovative modular homes under 40k use bamboo-framed exterior wall panels, which are now available as single-wall (for warm climates) or double-wall (for a wider range of temperatures). On the exterior, the Bonsai uses natural split bamboo siding. Based in Pahoa, Hawaii, the company seeks to protect and restore the planet by pioneering the use of timber-grade structural bamboo as a tree-free building material.
