Clarkson Valley homes and this kind of project
Our first visit for a home addition in Clarkson Valley is spent on the plat, setbacks and easements, then floor heights, rooflines and HVAC capacity, which tells us how large traditional homes from the 1970s and 1980s were put together.
The housing stock here: large 1970s and 1980s traditional homes on lots of about an acre.
On subdivision lots the recorded building line and a decades-old indenture decide what is possible.
Lots, exteriors and approvals in Clarkson Valley
Brick and wood exteriors needing trim repair and paint, original decks and patios ready for replacement with covered outdoor rooms.
Subdivision lots in Clarkson Valley 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 Clarkson Valley 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 Clarkson Valley, from Kehrs Mill Road estates to neighborhoods around Forest Hills Country Club.
What we watch for
Matching discontinued siding colors and weathered shingles on Clarkson Valley homes takes planning. Sometimes re-siding or re-roofing one full elevation gives a better result than trying to blend.
Site logistics matter: Clarkson Valley has lots of about an acre, so we agree with you where an excavator, a foundation crew, framers, a roofer and every interior trade will park, store material and carry out debris.
Permits and approvals in Clarkson Valley
For a home addition at a Clarkson Valley address, the paperwork goes to Clarkson Valley plan review with St. Louis County permits. Expect plan review plus footing, foundation, framing, trade, insulation and final inspections.
Exterior work in Clarkson Valley can also involve city architectural expectations for a uniformly traditional community, and we put that package together for you.
Schedule and getting to you
On site, a home addition in Clarkson Valley generally runs three to six months.
Clarkson Valley is I-64 to Clarkson Road, about thirty-five minutes from our Wentzville base. We plan crew days and deliveries around that drive so you get full working days on site.
What our home additions looks like

What moves the price in Clarkson Valley

- Complexity of the roof tie-in and exterior matching, especially brick.
- HVAC and electrical service upgrades.

Our step-by-step method for this work, and the factors that move its price, are laid out on the main home additions page. More about the area is on our Clarkson Valley page.
Home Additions in Clarkson Valley: common questions
How long does a home addition take in Clarkson Valley?
Design and permitting typically take two to four months. For Clarkson Valley we group trade visits to keep that schedule tight despite the drive.
Do I need approval beyond a permit for a home addition in Clarkson Valley?
Possibly. In Clarkson Valley you may be dealing with city architectural expectations for a uniformly traditional community. City or county approval and private approval are separate, and we prepare both submittals and wait for written approval before ordering materials.
Is it cheaper to build up or out?
Out is usually less expensive per square foot if the lot has room, because a second story requires structural upgrades below and removing the existing roof. Up makes sense when setbacks leave nowhere to go.
