Weldon Spring homes and this kind of project
Because Weldon Spring is made up of custom homes on an acre or more and the estates of Whitmoor, 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: custom homes from the 1970s onward on large lots, golf community estates and recent luxury construction.
Matching brick, stone and custom windows is the hard part, and we source them first.
Lots, exteriors and approvals in Weldon Spring
Wooded, sloped sites make for tall decks and multi-level outdoor spaces. Tree cover keeps surfaces damp, so we favor composite or PVC and rot-proof trim. Some properties use septic systems, which limits where additions and patios can go.
Additions to Weldon Spring homes must match demanding originals: brick and stone, steep roofs, custom windows. We source matching materials early, because a poor brick match on a house of this caliber is not acceptable.
What is included
A Weldon Spring addition with us includes feasibility review, design, structural engineering, permits, excavation, foundation, framing, roofing, windows, exterior finishes, all mechanical trades, insulation, drywall, flooring, trim and paint.
We take on home addition work across Weldon Spring, from the Highway 94 and Wolfrum Road area to Whitmoor Country Club and Weldon Spring Heights.
What we watch for
Rear-yard easements and building lines in Weldon Spring subdivisions are often tighter than owners expect. We confirm the buildable area from the recorded plat before anyone gets attached to a floor plan.
Working on rolling, wooded sites with real slope, as we do in Weldon Spring, we plan access for an excavator, a foundation crew, framers, a roofer and every interior trade before the first delivery arrives.
Permits and approvals in Weldon Spring
In Weldon Spring, a home addition is reviewed by the City of Weldon Spring or St. Charles County, depending on the parcel. What follows is plan review plus footing, foundation, framing, trade, insulation and final inspections.
Exterior work in Weldon Spring can also involve gated-community and subdivision architectural review, and we put that package together for you.
Schedule and getting to you
Most Weldon Spring clients see three to six months of construction for a home addition.
Weldon Spring is down I-64 to Highway 94, a little over twenty 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
Photographs from jobs we have built. We do not label photographs by town, so these may or may not be near Weldon Spring; they are here so you can judge the standard of finish before we meet.
What moves the price in Weldon Spring
We price home additions in Weldon Spring from a site visit, not a square-foot figure. These are the items that change the number.
- Complexity of the roof tie-in and exterior matching, especially brick.
- HVAC and electrical service upgrades.
More detail
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 Weldon Spring page.
Home Additions in Weldon Spring: common questions
How long does a home addition take in Weldon Spring?
Design and permitting typically take two to four months. In Weldon Spring, permit review by the City of Weldon Spring or St. Charles County, depending on the parcel and material lead times affect the start date more than our calendar does.
Do I need approval beyond a permit for a home addition in Weldon Spring?
Possibly. In Weldon Spring you may be dealing with gated-community and subdivision architectural review. City or county approval and private approval are separate, and we prepare both submittals and wait for written approval before ordering materials.
Will the addition match?
That is the goal. Siding profiles and shingles can usually be matched closely. Brick is harder on older houses, and we show you samples against the wall before committing.
