Lake St. Louis homes and this kind of project
Our first visit for a home addition in Lake St. Louis is spent on the plat, setbacks and easements, then floor heights, rooflines and HVAC capacity, which tells us how 1970s lake houses and the newer homes around Hawk Ridge were put together.
The housing stock here: a mix of 1970s and 1980s contemporaries, ranches and split-levels near the lakes, and larger 1990s to 2010s two-stories and villas in the Hawk Ridge area and south of the interstate.
On subdivision lots the recorded building line and a decades-old indenture decide what is possible.
Lots, exteriors and approvals in Lake St. Louis
Tall decks facing the water are the signature project. Many are original and overdue for replacement. Steep rear yards make footing access and stair design the hard part. The community association reviews decks, docks, colors and roofed structures.
Subdivision lots in Lake St. Louis 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
A Lake St. Louis 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 Lake St. Louis, from the Lake Saint Louis lakefront to Lake Saint Louise and Heritage of Hawk Ridge.
What we watch for
Rear-yard easements and building lines in Lake St. Louis 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 sloping, wooded lots that fall toward the water, as we do in Lake St. Louis, 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 Lake St. Louis
For a home addition at a Lake St. Louis address, the paperwork goes to the City of Lake Saint Louis. Expect plan review plus footing, foundation, framing, trade, insulation and final inspections.
Since this work shows from outside, also plan on the Lake Saint Louis Community Association. We prepare that submittal alongside the permit.
Schedule and getting to you
Plan on three to six months of site work for a home addition in Lake St. Louis, once permits and materials are in hand.
From our Wentzville base, Lake St. Louis is a short run east on I-70 or down Highway 40/61. That is close enough that your project lead can stop by most days.
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 Lake St. Louis; they are here so you can judge the standard of finish before we meet.
What moves the price in Lake St. Louis
We price home additions in Lake St. Louis 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.
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 Lake St. Louis page.
Home Additions in Lake St. Louis: common questions
How long does a home addition take in Lake St. Louis?
Design and permitting typically take two to four months. In Lake St. Louis, permit review by the City of Lake Saint Louis 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 Lake St. Louis?
Possibly. In Lake St. Louis you may be dealing with the Lake Saint Louis Community Association. 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.
