Home Additions in Chesterfield, Missouri

Chesterfield homes and this kind of project

Because Chesterfield is made up of large 1970s to 1990s two-stories and newer estate homes to the west, the first thing we check for a home addition here is the plat, setbacks and easements, then floor heights, rooflines and HVAC capacity.

The housing stock here: large 1970s to 1990s two-stories and ranches in established subdivisions, with newer estate homes to the west.

On subdivision lots the recorded building line and a decades-old indenture decide what is possible.

Lots, exteriors and approvals in Chesterfield

Brick fronts with wood or early hardboard siding elsewhere often need siding replacement. Mature lots favor screened porches and composite decks. Subdivision trustees review exterior changes.

Subdivision lots in Chesterfield have defined building lines and easements, and HOA indentures that may be decades old but still binding. Most additions go to the rear. Matching vinyl or hardboard siding that is no longer made sometimes means re-siding a whole elevation.

What is included

During Chesterfield additions we keep the existing house weather-tight and secure, build temporary dust walls at the tie-in, and schedule the breakthrough late so your daily life is disrupted for weeks rather than months.

We take on home addition work across Chesterfield, from neighborhoods off Clarkson, Baxter and Olive to Chesterfield Valley commercial district and the Wild Horse Creek Road corridor.

What we watch for

Matching discontinued siding colors and weathered shingles on Chesterfield homes takes planning. Sometimes re-siding or re-roofing one full elevation gives a better result than trying to blend.

Chesterfield properties tend to be generous, rolling lots with mature trees, and that affects how we stage materials, where an excavator, a foundation crew, framers, a roofer and every interior trade park and how debris leaves the site.

Permits and approvals in Chesterfield

In Chesterfield, a home addition is reviewed by Chesterfield's planning department together with the St. Louis County permit process. What follows is plan review plus footing, foundation, framing, trade, insulation and final inspections.

Since this work shows from outside, also plan on subdivision trustees. We prepare that submittal alongside the permit.

Schedule and getting to you

On site, a home addition in Chesterfield generally runs three to six months.

Chesterfield is down I-64 and over the Daniel Boone Bridge, just under half an hour from our Wentzville base. We plan crew days and deliveries around that drive so you get full working days on site.

What moves the price in Chesterfield

We price home additions in Chesterfield from a site visit, not a square-foot figure. These are the items that change the number.

• What the rooms are. A bedroom costs less per foot than a kitchen or bath.
• Complexity of the roof tie-in and exterior matching, especially brick.
