Philomath Home Addition Builder

Thinking about a home addition in Philomath? A seamless addition adds the room you need without the cost and upheaval of moving — and Red Umbrella has been building garages, ADUs, and additions across Benton County since 1969. Philomath’s position at the foot of the Coast Range means lots on the west side of town carry steeper grades, making garage siting and drainage planning more involved than on the valley floor.

Building a home addition in Philomath

Philomath sits 53 mi north-northwest of Eugene via I-5 & US-20. Blends established suburban lots with larger parcels on its edges — a familiar mix for siting a new build. Building permits here go through City of Philomath — a process we know well — and for a home addition, that shapes how the new space ties into existing rooflines, the foundation, and the permit path.

Locally, Philomath is known for Marys Peak (4,097 ft, highest point in the Oregon Coast Range), Marys River Park, Philomath Frolic & Rodeo, and we tailor every build to fit the lot, the neighborhood, and how you actually live.
