Alpine Home Addition Builder

Thinking about a home addition in Alpine? 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. Alpine’s hilltop setting among Coast Range vineyards means your garage or addition benefits from long views — and benefits from a builder who plans drainage for hillside lots, not flat-valley ones.

Building a home addition in Alpine

Alpine sits 35 mi northwest of Eugene via OR-99W & local roads. Is surrounded by working farmland where efu zoning and generous setbacks shape what — and where — you can build. Building permits here go through Benton 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, Alpine is known for Alpine Tavern (est. 1936), OSU Woodhall Vineyard, Alpine Century Bike Ride, Alsea Falls BLM access, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Why Alpine homeowners choose Red Umbrella

• Building since 1969 — you work directly with Bari, not a sales rep or a rotating cast of subs.
• Permits handled & up to 120% financing — we know Benton County and make the whole path simple.
