Located right up against an alley, this DADU & garage is for a family of four.
The design emphasized minimalism in style and content: we made the most with the least amount. How to fit 2.5 bath, 2 bedrooms in 1,000 sf was the biggest spatial challenge. Additionally, the design was constrained in its footprint and layout, as we reused an existing backyard studio.
This DADU is a typical example of an urban infill. Our challenge was to design to give the most privacy on the alley and the sides.
This DADU is a net zero building in terms of energy consumption. Passive house principles were incorporated into the design. We designed extra thick walls and roof assemblies and picked high performative mechanical systems.
