Next up in the Projex Group Top 20 favourite green rooftops list is the green roof at Mill Valley Cabins, California.

A project designed by Feldman Architecture along with Jori Hook Landscape Architecture, Mill Valley Cabins is nestled in a small stretch of woodland in San Francisco.

Featuring a blend of cultivated and wild growth, Mill Valley Cabins is home to a wide range of plants that thrive in and around the stone paths connecting the houses. However, the gardens have been organised carefully into pleasant rows.

The green roof, which connects the two structures of the home, was designed to meet a brief that asked for the building to be blended into the surrounding hillside. The roof garden also serves to satisfy the client's gardening habit.
