Home Additions
Home Additions in St. Charles, MO
More room for a growing family, without leaving the neighborhood you love. Bedrooms, family rooms, sunrooms, and garages.
Overview
Need More Space? Build It.
Moving means selling, buying, closing costs, and leaving a neighborhood you chose for a reason. An addition lets you stay put and get the space you need.
We design and build room additions, primary suites, family rooms, sunrooms, mudrooms, and garage additions throughout St. Charles County. Kyle has built homes from the ground up, so he handles the full addition: foundation, framing, roof tie-in, mechanicals, and finish work.
The goal is an addition that looks like it was always part of the house, with matching rooflines, siding, trim, and flooring transitions that make sense.

FAQ
Home Additions Questions
How much does a home addition cost?
It depends on size, foundation type, roof tie-in, and finishes. Additions are priced per project, not per square foot, so the best way to get a real number is a site visit. Estimates are free.
How long does an addition take?
Most additions take a few months from permit to completion. Design and permitting come first, then construction. You’ll get a timeline with your estimate.
Do I need an architect or engineer?
Many additions need drawings and sometimes engineering for permits. We coordinate that for you so you’re not managing multiple companies.
Can you match my existing house?
Yes. We match rooflines, siding, windows, trim, and interior finishes so the addition blends in.
Is it better to add on or move?
Often adding on is the better value, especially if you like your location. Kyle is also a licensed real estate agent and can give you an honest comparison.
