Home Additions in Pittsburgh
When a house you love runs out of room, a home addition lets you stay on the street you chose. JL Home Builders designs and builds room additions, second story additions, bump outs, in law suites and primary suites across Pittsburgh.
Our lots are steep, narrow and old, so an addition here starts with the ground: setbacks, zoning, the hillside, and what the existing foundation can carry.
From there we plan a structure that ties into the house, so the finished addition looks like it was always part of it.
What Is Included
We coordinate the new construction with the rooms it connects to, so the kitchen, bath or bedroom on the other side of the wall is finished with the same care. We manage every phase from the first site visit to the final inspection.

How We Work
-
Consultation
We meet at your home or our Pittsburgh showroom, walk the space, and talk through what you want the finished room to do.
-
Design and written estimate
You get a design, a materials list and a written estimate with a schedule built for your project.

Construction
Our own crew handles demolition through finish work, with one project lead keeping you informed every week.
-
Final walkthrough
We walk the finished project with you, close out permits and inspections, and stand behind the work.
It Starts With the Lot
Every addition is different, so every schedule is different. Design, zoning review and the site itself all shape the plan. We tell you up front what the lot allows and what the foundation needs, and you get a written schedule before work begins.
Additions We Build
Whether you need one more bedroom or a full second floor, the goal is the same: more room in the house you already love.

Matching the Existing House
We match rooflines, siding, brick, trim profiles and window styles so the addition reads as part of the original house, and we tie the new floor and finishes into the existing rooms.
Why Homeowners Choose JL Home Builders
What sets us apart on additions is planning. Our team has built on the hills, the clay and the century old foundations that make this city what it is.
What Our Clients Say
Popular Questions
It depends on the addition. Design, engineering, zoning review and permits all come before construction, and a one story bump out is simpler than a second story. We give you a written schedule built for your project during the consultation.
Often, yes, but the lot decides a lot of the design. Setbacks and lot coverage rules limit how far you can build toward a property line, and a hillside may need a retaining wall, soil evaluation or a deeper foundation. We check zoning and walk the site before drawing anything.
That is the goal on every project. We match rooflines, siding, brick, trim profiles and window styles so the addition reads as part of the original house, and we tie the new floor and finishes into the existing rooms.
