Frontenac homes and this kind of project
Our first visit for a home addition in Frontenac is spent on the plat, setbacks and easements, then floor heights, rooflines and HVAC capacity, which tells us how estate homes from mid-century to new were put together.
The housing stock here: estate homes on lots of an acre or more, from mid-century to new.
Matching brick, stone and custom windows is the hard part, and we source them first.
Lots, exteriors and approvals in Frontenac
Covered terraces, pavilions and additions with close attention to the city's site and tree rules.
Additions to Frontenac 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
During Frontenac 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 in and around estates off Clayton, Geyer and Spoede roads.
What we watch for
Matching discontinued siding colors and weathered shingles on Frontenac homes takes planning. Sometimes re-siding or re-roofing one full elevation gives a better result than trying to blend.
Working on acre-plus sites, as we do in Frontenac, 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 Frontenac
For a home addition at a Frontenac address, the paperwork goes to the City of Frontenac. Expect plan review plus footing, foundation, framing, trade, insulation and final inspections.
Since this work shows from outside, also plan on the city's architectural review. 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 Frontenac, once permits and materials are in hand.
Frontenac sits toward the edge of our range: down I-64 to Lindbergh, around 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 Frontenac; they are here so you can judge the standard of finish before we meet.
What moves the price in Frontenac
We price home additions in Frontenac 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 Frontenac page.
Home Additions in Frontenac: common questions
How long does a home addition take in Frontenac?
Design and permitting typically take two to four months. For Frontenac we group trade visits to keep that schedule tight despite the drive.
Do I need approval beyond a permit for a home addition in Frontenac?
Possibly. In Frontenac you may be dealing with the city's architectural review. 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.
