Everything Your Home Addition Covers
No surprises, no change-order games — here's exactly what's built into every project before we ever hand you a price.
Design & Engineering
We measure your home and design the addition to blend with your existing architecture, with structural engineering coordinated for you.
Foundation & Framing
Footings, foundation, framing, and roof tie-in — built to code and tied structurally into your existing home.
Exterior & Roofing
Siding, windows, and roofing matched to your existing home, so the addition looks like it was always there.
Interior Finishes
Insulation, drywall, flooring, paint, and trim — finished clean and move-in ready.
Electrical — Always Included
Always part of the scope and priced by the number of points and fixtures — outlets, switches, lighting, and panel work by licensed electricians.
Full Permit & Code Handling
We pull and manage every required permit, engineering review, and inspection ourselves — you never deal with the city.
Every addition includes your free AI visualization, a one-page contract, and a Project Manager who's your single point of contact start to finish.

How Much Does a Home Addition Actually Cost?
Every addition is different — size, structure, and finishes decide the price. Here's how we scope it, so you know what you're paying for before you sign.
Bump-Out
Extend an existing room by a few feet — a kitchen, family room, or primary bedroom.
Room Addition
Our most common addition — a new bedroom, office, or living space built onto your home.
Second Story / Suite
Second-story additions, primary suites, and multi-room additions with structural work.
Pricing depends on size, structure, foundation type and finishes. After a free site visit and AI design, your Project Manager gives you one firm price before you sign.
Your price is locked into the 1-page contract the day you sign — it only changes if you ask for something new, never because of a "surprise" we found later.

What Decides the Price of an Addition
Honest answer: six things move your number. Here is how each one works, so there are no surprises when you get your price.
Size
Square footage is the biggest driver — a small bump-out and a full second story are very different projects.
Foundation & Site
Slab, crawlspace, or full foundation, plus access and soil conditions on your lot.
Structure
Roof tie-in, load-bearing walls, and engineering — a second story needs the most.
Finishes
Flooring, cabinetry, tile, and fixtures — from solid builder-grade to fully custom.
Utilities & Systems
Wiring, panel capacity, and any plumbing or heating extended to the new space by licensed trades.
Permits & Engineering
Permit fees and engineering reviews vary by city and county. We manage them and include them in your one price.
Your Project Manager walks you through each of these on site, then gives you one firm price in a one-page contract.

Home Additions FAQ
It depends on size, foundation, structure, and finishes — a small bump-out and a second story are very different projects. After a free site visit and AI design, your Project Manager gives you one firm price in a one-page contract, not a ballpark that grows later.
A small bump-out usually takes 1–3 weeks, a room addition 3–6 weeks, and a second story or a major rebuild of the home's structure 2–4 months — plus permit review time, which your city sets. Your Project Manager gives you a real start-to-finish date before work begins.
Almost never. An addition is built outside your living space, so you stay in your home. We protect the area where the new space connects to your existing rooms, and we tell you ahead of time about any short interruptions like power or water shutoffs.
Yes. We pull and manage every required permit, coordinate structural engineering where it's required, and schedule the inspections — you never deal with the city or the paperwork.

An addition starts weeks before the first footing is dug — here's what actually drives the calendar.
Crew Calendars Fill First
We run 10+ dedicated crews, and each one is booked as projects are confirmed — not first-come, first-served on the day you want to start. Locking your spot earlier means an earlier start date, not a faster rush job.
Engineering & Permits Take Lead Time
Engineering, city permit review, and custom materials all take lead time. Starting the free AI design now is what starts that clock — the work itself can't begin until permits and materials are in hand.
Your Estimate Is Locked, Not Floating
Once your Project Manager prices your project from current material and labor costs, that number holds through your 1-page contract — it won't drift upward if you wait to sign.
Catch the Dry Building Season
Foundations, framing, and roofing go fastest in dry weather — in the Northwest, that means getting permits in early to catch the summer building season.
