This one-bedroom ADU adapts a pre-designed unit to fit a constrained backyard site in Santa Cruz, integrating with an existing alley-accessed garage.

Careful structural coordination and detailing ensured the new addition could connect to the garage without compromising waterproofing or integrity. Within a modest budget, targeted design upgrades—such as an expanded kitchen island and optimized laundry—enhance functionality and livability.

The result is a compact, efficient dwelling tailored to both site constraints and client needs.
