Home Additions Built to Last Generations
Whether you're adding square footage, a second story, or an entirely new wing — we manage every detail so the result feels like it was always part of your home.
More Space, Done Right
A home addition is one of the most complex projects a homeowner can take on — you're expanding a structure that's already occupied, tying into existing systems, and trying to make something new feel like it's always been there.
We've managed additions across the Ogden Valley ranging from single-room expansions to full two-story additions with finished basements. We know where these projects go wrong — and how to keep yours on track.
Single-room additions, great room expansions, sunrooms, mudrooms, and bonus spaces that tie seamlessly into your existing footprint.
Full second-floor additions including structural upgrades, staircases, bedrooms, and bathrooms — designed to match your existing home's character.
Attached garage builds, garage expansions, or conversions into finished living space — permitted and built to code.
Master bedroom and bathroom additions that give you the space and privacy you've outgrown — without moving.
Large-scale additions spanning multiple phases, coordinated to minimize disruption and manage budget across a longer timeline.

Our management fee is agreed to upfront and never changes without your sign-off. No surprises. No buried markup.

Addition Project FAQ
The questions every homeowner asks before starting an addition project.
In most cases, no — but it depends on the scope and where we're tying into your existing home. We'll be direct with you during scoping about what disruption to expect and how we'll minimize it. We plan the sequencing specifically to keep your home livable as long as possible.
A straightforward room addition typically runs 3–5 months once permits are in hand. A full two-story addition or major expansion can run 6–12 months. Permitting timelines in Weber and Morgan counties vary — we build that into your schedule from day one so there are no surprises.
That's one of the most important parts of the job and something we take seriously. We match rooflines, siding, trim profiles, and interior finishes so the addition feels integrated, not tacked on. We'll talk through this in detail during the design and estimating phases.
Every line item — demo, framing, roofing, windows, electrical, plumbing, HVAC, insulation, drywall, finishes, and our management fee. Nothing is bundled or hidden. You'll see each subcontractor bid and can ask questions about any line before you sign.
Yes. Permitting is part of our process — we pull the permits, coordinate with the county, schedule inspections, and make sure every phase passes before moving forward. This protects your investment and ensures the addition is insurable and appraisable.
