Room Addition in Mt Prospect, IL

We're a family-owned construction company with over 20 years building in Mt Prospect, IL and the surrounding NW Suburbs. We've done enough room additions to know where projects stall — permit delays, foundation surprises, mismatched trim — and we plan for those problems before they hit your timeline or your budget.

New additions only work long-term when the structural and mechanical connections are done right. We tie into your existing framing, electrical, HVAC, and plumbing the correct way. When the job is done, the new space matches your home's style and functions like part of the original build.

Building in Mt Prospect, IL means working with Illinois winters, and that matters a lot for room additions. Frost depth here runs around 42 inches, so footings have to go deep enough to stay stable through freeze-thaw cycles. We also account for the weight of heavy snow loads when we size the roof framing on any new addition. Skipping those details early creates cracked foundations and sagging rooflines a few years down the road. We've seen the damage that comes from cutting those corners, and we don't cut them.

New Additions That Match Your Existing Home

A lot of contractors can frame a box and call it an addition. What's harder is making new additions blend with a home that was built 30 or 40 years ago. We match rooflines, siding profiles, window styles, and interior trim so the transition from old to new is invisible.

That matters for resale value and for how the space actually feels to live in.
