To realize the need of having sustainable green house, the architect added a new 484 sq ft loft unit above the garage building. This was built around and above the existing tree on the lot, providing a twisting structure that may maximize the sun light capture for natural lighting. A giant window at the top level support the natural lighting and view access.
Some strategies were implemented to achieve high sustainability. Alternative energy used is solar, with a series of roof panels, and rainwater collection is provided.
