Home Additions

Home Additions That Feel Like They Were Always There

Growing family? Need a dedicated office, a bigger kitchen, or a primary suite? We add the space you need and match it seamlessly to the home you already love.

An addition is the one job where the finish work decides whether it worked. Anyone can frame a box on the back of a house. Getting the rooflines to meet properly, the siding courses to line up, and the new windows to match the old ones is what makes it read as part of the house instead of something stuck on it. That is the part we spend the time on.

Additions we build

  • Room and bump-out additions: family rooms, offices, bedrooms
  • Second-story additions and expansions
  • In-law suites and multi-generational living spaces
  • Primary suite and expanded kitchen additions
  • Sunrooms, mudrooms, and attached garages

Built to match your home

The difference between a good addition and a great one is in the details: matching the rooflines, siding, window styles, and interior finishes so everything flows together. We plan carefully at the design stage so the transition between old and new is seamless.

One team, start to finish

Additions touch nearly every trade: foundation, framing, roofing, siding, electrical, plumbing, HVAC, and finish work. As your design-build general contractor, we coordinate all of it, manage the schedule and the subcontractors, handle permits and inspections, and keep you informed the whole way through.

FAQ

Common questions

What kinds of additions do you build?

We build room additions, second-story additions, in-law and multi-generational suites, sunrooms, expanded kitchens and primary suites, garages, and more. If you need more space, we can help you plan the right way to add it.

Will the addition match the rest of my house?

Yes. Matching the existing rooflines, siding, trim, and finishes is a big part of doing an addition well. Our goal is for the new space to look like it was always part of your home.

Do I need permits for a home addition?

Inside city limits, almost always. As your general contractor we will tell you which permits your addition needs, get the office what it asks for, and be there for the inspections, so you are not chasing the village office between work and dinner. Outside city limits the requirements are lighter and we will say so.

Is it worth adding on versus moving?

For many families, adding onto a home they love, in a location and neighborhood they’re happy in, is a smart alternative to buying and moving. We’re glad to talk through the scope and give you a clear estimate so you can weigh it.
