California St Duplex

1500 sf. Apartment / 675 sf. Apartment / 225 sf. studio

Completed 2016 by Mast & Co.

It’s so much fun when you get to design a project with a really creative contractor and his artist wife. This duplex design was in collaboration with the owners, who live in the larger unit and rent the smaller one. In addition, there is a small artist’s studio on the main level.

The building is constructed using thick double stud walls for high insulation value and to minimize thermal bridging. It features triple glassed windows, a covered dining deck at the second level, and a roof deck with a tub on the south.
