Registered Architect–Led
Design – Permit – Build, In‑House
Earth Advantage & Advanced Framing
Portland and Beyond
One integrated team, from first sketch to final inspection.
Led by registered architect Eli Green, we combine design, permitting expertise, and in-house construction for homeowners across the Portland metro area — providing one clear, accountable path from first sketch to finished space.
“Calm, considered architecture — not a rushed sales process. We build one relationship, not three handoffs.”
Start with a proven, architect-designed plan.
Thoughtfully developed for livability and efficiency, built to Earth Advantage standards — then personalized to feel entirely your own.
Why a predesigned ADU makes sense
Starting with a predesigned plan offers the balance of architectural quality and project efficiency — you skip the lengthy custom design phase and gain immediate budget clarity, while still personalizing finishes and fixtures to make it your own.
Specialized permitting: remodels & the FIR program
We have deep experience with Portland’s Field Issuance Remodel program for custom remodels. Important: ADUs cannot be legally permitted under FIR — we ensure your project takes the correct, compliant path.

Building an ADU shouldn’t mean compromising on design.
