Primary Suite Additions in Portland, OR
A master bedroom, spa bathroom, and walk-in closet — designed and built as one addition.
A primary suite is our most-requested addition: a real owner's retreat set apart from the kids' rooms, with a bath and closet sized for how you actually live. We plan the bedroom, bathroom, and closet together so circulation, daylight, and plumbing all resolve cleanly.
Whether the master suite lands on the main floor for aging in place or over the garage to save yard space, it is engineered alongside the existing structure — proper foundations, framing, and systems, finished to match the rest of the house.

Frequently Asked
Primary Suite Addition FAQs
What Portland and Vancouver homeowners ask before they begin.
Expect the upper end of the $400–$700 per square foot addition range, since a master suite carries full bathroom plumbing and more structural work than a plain room addition. See our Portland remodeling cost guide for detailed ranges.
