Quality Home Building Services in Newtown Square
Newtown Square sits at the eastern edge of our territory, in Delaware County, and the homes here reflect it: large lots, mature trees, and estates that have been shaped and reshaped over generations. McComsey Builders is a second-generation, family-owned custom home builder, founded by Bob McComsey Sr. in 1986 and run today by his sons Bob and Mike. We design and build custom homes, additions, and kitchens for Newtown Square families who want a builder that treats their home as one of one, never a plan pulled from a drawer.
The scale and character of this area attract owners who are serious about building. When you build a custom home in Newtown Square with us, we start early: evaluating buildability, helping source the right architect, and staying with you from the first conversation to the day we hand over the keys. The large wooded lots common near Ridley Creek State Park and Tyler Arboretum require a builder who can read a property, understand drainage and grade, and site a home that belongs on the land rather than just sitting on it. That kind of judgment comes from forty years of building in this region, two generations deep.
We are boutique by design. Every home and every kitchen is one of one, which means we sit with you, sometimes on lawn chairs in an empty house, and draw cabinets specific to how your family cooks and lives. We build that cabinetry in our own shop. When trees come down on your property during site prep, we mill them into the floors, beams, and counters of the new home. If you want to add on to your Newtown Square home or put a barn, pool house, or carriage house on your acreage, you get the same craft and the same family name behind it.
We have done kitchen work in Newtown Square before, including a kitchen bump-out and mudroom renovation on an existing home, and that kind of project is where our dust-mitigation approach matters most. We build temporary kitchens, dust walls, and negative-pressure containment so your family can keep living at home while we work. You also have a clear view of the whole project through JobTread: daily field reports, photos, the live budget, every file, and weekly on-site walk-throughs. Our kitchens come in within 5 percent of the original budget. The McComsey name is on every project here, and we intend to keep it there.
If your project is bigger than a kitchen, we handle that too. Newtown Square homeowners have asked us to remodel their kitchen as part of a larger renovation, and we are equally comfortable building a full addition or designing and constructing a new custom home on a vacant parcel. We are Andersen Certified and licensed in Pennsylvania (PA015145), and we bring that standard to every project in Delaware County the same way we bring it to Chester County.
Our Newtown Square Remodeling Services
Custom Home Building
A home built around how your family lives, on the lot you have chosen or one we help you find. We come in early, evaluate buildability, source the right architect, and stay with you from the first walkthrough to the day we hand over the keys. Every home we build is one of one.
Home Additions and Renovations
More room, better flow, modern systems, and a home that finally feels like your own. We build temporary kitchens, dust walls, and negative-pressure containment so your family can keep living at home while we work, including whole-home and major historic renovations other builders will not take on.
Kitchen Remodeling
Cabinets we draw with you and build in our own shop. New layouts, structural openings, stone counters, and a kitchen that finally fits how you cook and gather. Our kitchens come in within 5 percent of the original budget, and we hand you the keys when we said we would.
Accessory Structures
Horse barns, party barns, car barns, pool houses, and the structures that turn a property into the place your family wants to spend the weekend. We bring the same craft and transparent process to an outbuilding that we bring to the main house.
Commercial Construction
Tenant fit-outs and full ground-up commercial builds. We work directly with building owners, scope every line transparently, and protect the move-in date so your business opens on schedule.

Forty Years, Second Generation Hands-On

Our History in Newtown Square
McComsey Builders has been part of the greater Chester County and Delaware County region for forty years. Bob McComsey Sr. founded the company in 1986 out of Parkesburg, and his sons Bob and Mike run it today, extending the work into the eastern suburbs where Newtown Square homeowners are asking for the same standard of custom building their neighbors closer to the borough have come to expect.
Newtown Square is a natural part of our reach. The Colonial Pennsylvania Farmstead on North Sandy Flash Drive is a reminder of how long people have been building here and how much the land and the history of this area matter to the families who live on it. Rose Tree Park, a short drive from many of the estates we serve, is where those same families spend their weekends. We build with that context in mind, respecting the character of the area and treating every project as something that should belong here, not just occupy the lot. The McComsey name is on every job we build in Newtown Square, and that accountability does not change because we crossed the county line.

Why hire a Chester County builder for a Newtown Square project?
The larger estates and wooded lots common in Newtown Square, near Ridley Creek State Park, ask for a builder who has worked on comparable properties for decades. We bring forty years of regional experience, in-house cabinetry, and a second-generation family name to every project. Our base in Parkesburg is a short drive, and we treat Delaware County projects with the same care we give our Chester County clients. You can read more about us on our About page.
Does McComsey build barns and accessory structures in Newtown Square?
Yes. On the larger lots common in Newtown Square, we build horse barns, party barns, car barns, pool houses, and basketball courts as part of our accessory structures work. These are built with the same craft and in-house standards as the main house.
