Wren Home Addition Builder

Thinking about a home addition in Wren? 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. Wren has a Benton County community plan that shapes allowable land uses — we review those rural-UGB standards before design so your garage or shop doesn’t trigger a variance.

Building a home addition in Wren

Wren sits 60 mi northwest of Eugene via I-5 & US-20. Is rural and largely unincorporated, which usually means county-level permitting, septic siting, and room for larger shops and outbuildings. 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, Wren is known for Marys River, US-20 & OR-223 junction, established via Oregon Pacific Railroad 1886, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Why Wren homeowners choose Red Umbrella

• Master Electrician in-house — owner Bari Swartz wires it himself, to code, no waiting on a sub.
• 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.
