Room Additions & Suites in Swisshome, OR

Thinking about a home addition in Swisshome? 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 Lane County since 1969. Swisshome sits deep in the Coast Range where the North Fork Siuslaw River meets the main stem; lots are narrow, heavily wooded, and require site-specific engineering for any new foundation due to steep sideslopes and high-rainfall soil conditions — every project here benefits from a geotechnical review before design begins.

Building a home addition in Swisshome

Swisshome sits 45 mi west of Eugene on Highway 36 in the Coast Range. Follows a river corridor, so floodplain mapping and riparian setbacks are real factors we plan around from day one. Building permits here go through Lane County — 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, Swisshome is known for the North Fork Siuslaw River confluence and the dense Coast Range corridor on Highway 36, and we tailor every build to fit the lot, the neighborhood, and how you actually live.
