Des Peres homes and this kind of project
Our first visit for a home addition in Des Peres is spent on the plat, setbacks and easements, then floor heights, rooflines and HVAC capacity, which tells us how original ranches and the large new homes replacing them were put together.
The housing stock here: a mix of mid-century ranches and large homes built since 2000.
Ranches extend gracefully to the rear under a matching low roof.
Lots, exteriors and approvals in Des Peres
Screened porches, covered patios and additions. Lot coverage limits are a real constraint given the size of new homes.
Ranch homes in Des Peres extend well. A rear addition under a matching low-slope gable, or a primary suite wing, can look completely original. Lot coverage rules and mature tree protection are the usual constraints.
What is included
A Des Peres 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 in and around neighborhoods off Manchester, Ballas and Dougherty Ferry roads.
What we watch for
Rear-yard easements and building lines in Des Peres subdivisions are often tighter than owners expect. We confirm the buildable area from the recorded plat before anyone gets attached to a floor plan.
Site logistics matter: Des Peres has lots where coverage limits are a real constraint, 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 Des Peres
The City of Des Peres is where we file for a home addition in Des Peres, and the job will see plan review plus footing, foundation, framing, trade, insulation and final inspections.
Since this work shows from outside, also plan on lot-coverage and height limits. 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 Des Peres, once permits and materials are in hand.
Des Peres sits toward the edge of our range: I-64 to I-270 south, about forty minutes. We group trade visits and deliveries carefully for projects at that distance, and we take them on when the scope justifies a dedicated crew.
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 Des Peres; they are here so you can judge the standard of finish before we meet.
What moves the price in Des Peres
We price home additions in Des Peres from a site visit, not a square-foot figure. These are the items that change the number.
- HVAC and electrical service upgrades.
- Foundation type: slab, crawlspace or basement.
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 Des Peres page.
Home Additions in Des Peres: common questions
How long does a home addition take in Des Peres?
Design and permitting typically take two to four months. For Des Peres we group trade visits to keep that schedule tight despite the drive.
Do I need approval beyond a permit for a home addition in Des Peres?
Possibly. In Des Peres you may be dealing with lot-coverage and height limits. City or county approval and private approval are separate, and we prepare both submittals and wait for written approval before ordering materials.
Can we live in the house during construction?
In most cases. We build the shell first and break through the connecting wall near the end, which limits dust and disruption to a few weeks.
