Additions that disappear into the original house
The mark of a good addition is that you can't tell where the old house ends and the new one begins. That takes matching the siding, the roofline, the window style, and the interior trim — details a lot of contractors skip. We treat the match as part of the job, not an upgrade.
Additions are also the project where structure and permitting matter most. We handle the engineering, the foundation tie-in, and every permit in-house, so the new space is sound and legal — not a future problem when you sell.
Because it's a fixed-price contract, the surprises that hide in a tie-in — an existing footing that's shallower than expected, framing that isn't square — are ours to absorb. You approve one number and we build to it.
What's included
Every project is one fixed-price contract with the same licensed crew from consultation through final walkthrough.
Design + structural engineering
We design the addition and handle the structural engineering for the foundation, framing, and tie-in to your existing home.
Full permitting
Every permit pulled and managed in-house, with inspections scheduled — additions require several, and we track them all.
Foundation + framing
New foundation and framing tied into your existing structure correctly, built to Oregon code and the local climate.
Exterior match
Siding, roofing, windows, and trim matched to your home so the addition reads as original, not bolted-on.
Systems extension
HVAC, electrical, and plumbing extended into the new space by licensed trades and sized for the added load.
Interior finishes
Insulation, drywall, flooring, and trim finished to match the rest of your home.

Frequently asked
How much does a home addition cost in Eugene?+
A typical room or primary-suite addition runs $60k–$120k including permits; larger and second-story additions cost more. You get a fixed price in writing after the on-site walkthrough.
How long does an addition take?+
Usually 8–14 weeks including permitting for a single-room or suite addition. We give you a milestone schedule with buffer before you sign.
Can you match my existing home?+
Yes — matching siding, roofline, windows, and trim is part of how we work. On older homes we'll match crown, casing, and profiles so the addition blends in.
Do you handle the engineering and permits?+
Yes, both, in-house. Additions need structural engineering and multiple permits, and we manage the whole process so you don't have to.
