City living just got an upgrade. The Urban Series ADUs are made for places like Seattle and Portland, where space is tight but style is non-negotiable. Each plan uses a narrow footprint and clever design to make room for everything that matters. Add flexible layouts, multi-unit options, and a clean modern look that feels right at home for young professionals or anyone who wants to mix good design with smart investment.
We handle the complete build process from start to finish.
You’ll love the smart use of space, clean lines, and big-city feel. These ADUs were designed for tight urban lots that need to work harder, not just look good. Each one blends modern design with real function and all the comforts of home.
