Troy homes and this kind of project
Because Troy is made up of a historic center ringed by 1990s-and-later subdivisions, 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: a historic center, 1990s to current subdivisions, and rural property surrounding town.
On subdivision lots the recorded building line and a decades-old indenture decide what is possible.
Lots, exteriors and approvals in Troy
Decks and patio covers are frequent requests. Many lots back to fields with full sun and wind exposure.
Subdivision lots in Troy 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 Troy 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 Troy, from historic Main Street to subdivisions along Highway 47 and Highway 61.
What we watch for
Rear-yard easements and building lines in Troy subdivisions are often tighter than owners expect. We confirm the buildable area from the recorded plat before anyone gets attached to a floor plan.
Troy properties tend to be subdivision lots that often back to open fields, and that affects how we stage materials, where an excavator, a foundation crew, framers, a roofer and every interior trade park and how debris leaves the site.
Permits and approvals in Troy
In Troy, a home addition is reviewed by the City of Troy or Lincoln County. What follows is plan review plus footing, foundation, framing, trade, insulation and final inspections.
Since this work shows from outside, also plan on subdivision covenants. We prepare that submittal alongside the permit.
Schedule and getting to you
Most Troy clients see three to six months of construction for a home addition.
Troy is straight north on Highway 61, 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 Troy; they are here so you can judge the standard of finish before we meet.
What moves the price in Troy
We price home additions in Troy 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 Troy page.
Home Additions in Troy: common questions
How long does a home addition take in Troy?
Design and permitting typically take two to four months. In Troy, permit review by the City of Troy or Lincoln County 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 Troy?
Possibly. In Troy you may be dealing with subdivision covenants. 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.
