Ladue homes and this kind of project
A home addition in Ladue means working in architect-designed houses from the 1920s to 1950s and newer estates, so on our first visit we look at the plat, setbacks and easements, then floor heights, rooflines and HVAC capacity.
The housing stock here: architect-designed homes from the 1920s to 1950s, mid-century ranches and new estates on large lots.
An addition to an old house is set back and kept subordinate, with matching proportions, and may need board approval.
Lots, exteriors and approvals in Ladue
Wood window and trim restoration, additions designed to be indistinguishable from the original, and terraces and porches. Architectural review is thorough.
Adding onto an old Ladue house is a design problem first. Rooflines, window proportions, siding exposure and foundation height all have to relate to the original, and review boards in historic areas will insist on it. We set additions back and keep them subordinate to the main house.
What is included
A Ladue 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 lanes off Ladue, Warson and Litzsinger roads.
What we watch for
Matching discontinued siding colors and weathered shingles on Ladue homes takes planning. Sometimes re-siding or re-roofing one full elevation gives a better result than trying to blend.
Working on large lots on winding private lanes, as we do in Ladue, 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 Ladue
In Ladue, a home addition is reviewed by Ladue's building department. What follows is plan review plus footing, foundation, framing, trade, insulation and final inspections.
Exterior work in Ladue can also involve a thorough architectural review board, and we put that package together for you.
Schedule and getting to you
Plan on three to six months of site work for a home addition in Ladue, once permits and materials are in hand.
Ladue sits toward the edge of our range: I-64 east past Lindbergh, a little over forty minutes in normal traffic. 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 Ladue; they are here so you can judge the standard of finish before we meet.
What moves the price in Ladue
We price home additions in Ladue from a site visit, not a square-foot figure. These are the items that change the number.
- Foundation type: slab, crawlspace or basement.
- What the rooms are. A bedroom costs less per foot than a kitchen or bath.
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 Ladue page.
Home Additions in Ladue: common questions
How long does a home addition take in Ladue?
Design and permitting typically take two to four months. For Ladue we group trade visits to keep that schedule tight despite the drive.
Do I need approval beyond a permit for a home addition in Ladue?
Possibly. In Ladue you may be dealing with a thorough architectural review board. 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.
