What makes Custom Home Building a good fit
Custom home building takes patience, vision, and the budget to see it through. We’d rather have an honest conversation about whether this is the right move for your family than start a project that’s set up to disappoint you a year in.
Good Fit
Not a Fit
You’ve toured every listing in your school district. You’ve sketched a renovation of your current house and hit the same wall: it can’t realistically become what you want. The lot is too tight, the foundation is wrong, the layout fights every plan.
We help you decide whether building, moving, or renovating makes the most sense for your situation. If the answer is to build, we start from scratch on a lot that fits the home, not the other way around. You get a clear, honest comparison so the decision is yours and you’re confident in it.
Most homes were designed for a life that isn’t yours. The kitchen is in the wrong place. The kids’ rooms are upstairs and your office is in the basement. The back of the house faces north when you want morning light.
A custom home is your chance to fix all of it. We start with a deep design process focused on how you live now and how you’ll live ten and twenty years from now. Rooms get purpose. Circulation gets thought through. Architecture and finishes reflect your style, so the home feels uniquely yours from the moment you walk in.
Drafty windows. Knob-and-tube wiring. A boiler that should have been replaced ten years ago. If you’ve been patching old systems for years, what you want is a home built right from the foundation up.
We deliver that with serious insulation, well-sealed windows, modern mechanicals, and long-life materials chosen for the climate and how you’ll use your home.

The McComsey difference
Our name has been on the trucks since 1986 — and on every project we’ve ever built. Here’s what that means when it’s on yours.
We’re boutique by design. Every home and every kitchen is one of one. We start by sitting down with you, sometimes literally on lawn chairs in an empty house, and we draw cabinets specific to how you cook and gather. When trees come down on your property, we mill them into the floors, beams, and counters of your new home.
You’ll get a JobTread login with daily field reports, photos, the live budget, every file, and a direct line to our team. Weekly walk-throughs happen on site. You see what we see. Our kitchens come in within 5% of the original budget, and we hand you the keys when we said we would.
Bob and Mike took over from their dad, and the company they are building looks like the one they grew up around: tight communication, in-house cabinetry, a trusted bench of architects and trade partners, and a small team that does serious work. The McComsey name is on every job, and we treat your home like it is our legacy too.
Process
We created six clear steps so that once we start building there aren’t surprises. We take our time getting the budget right so the build can move fast and we limit disruption to your life.
It starts with a conversation. We ask who sent you our way, whether you have plans yet, and the kind of budget you’re working with. The goal is to make sure we’re the right team for what you have in mind before either of us spends another hour on it.
We come out to the property, walk the space with you, and review your plans if you have them. If you don’t have plans yet, we take photos and talk through the scope of work. You get the benefit of forty years of doing this work, telling you straight what will and won’t work and how a renovation or addition really comes together.
We send the plans out to our trade partners, scope every piece of the job, and on bigger or more complex projects, bring them back to the property for a second walkthrough. Their input is what gets us to a real, line-item budget.
We take the trade partner proposals, fill in anything missing, and build out a detailed Excel budget with specific line items. Then we sit down with you and walk every single line. You see why each piece costs and why, what’s included, and where there’s room to flex. By the time we're done, we're all reading the same numbers on the same page.
Once the budget feels right and we agree on a timeline, we lock it in as a signed approved order in JobTread. That's your starting point. As real-life decisions and changes come up along the way, every cost change gets documented against that baseline, so nothing’s ever a surprise.
Before we break ground, we introduce you to the people who’ll be running your project day to day. That means Mike, Evan, and your field lead. You’ll get their phone numbers, so that you know who to call, and any one of us is reachable when you need an answer.
Investment
Pricing depends on what you’re building, where you’re building, and the materials and systems you choose. Below are three rough tiers to set expectations, with the understanding that every custom home is a custom price.
Our base level for a quality custom home, with our standard finishes, mechanicals, and structural details.
– Foundational design work alongside an architect from our network
– Standard mechanical systems and finishes
– JobTread access throughout the project
– Weekly walk-throughs on site
Higher-end finishes, more sophisticated mechanicals, more design complexity. Where most of our custom builds land.
– Everything in Standard
– Higher-grade finishes and selections
– More involved mechanical systems (geothermal, advanced insulation, etc.)
– Custom in-house cabinetry from our shop
Top-tier finishes, advanced systems, and the most demanding structural and design work. The legacy build.
– Everything in Deluxe
– Bespoke materials, including milling lumber from your own property when applicable
– Advanced systems (full home automation, ICF wall construction, imported windows, geothermal plus solar where appropriate)
– Architectural complexity
A note on what these tiers don’t cover: Construction is one part of a custom home. Soft costs come before the first shovel goes in the ground: civil engineering, architectural fees, sewer or well or septic, driveway, stormwater management, electrical service upgrades, and PennDOT permits if your driveway connects to a state highway. Those soft costs can run $100,000 or more. We’ll walk you through every line before you sign anything.
Common Upgrades
Most of our custom home clients come in knowing the basics they want. A handful of upgrades come up over and over again. We’ve built all of these into recent homes.
Built into a dedicated room with the ceiling height, depth, and lighting the swing demands, wired for the launch monitor and screen setup you want.
Fitted to whatever your training looks like, with reinforced flooring for heavy lifts, rubber matting where it counts, and the ventilation a working gym actually needs.
Built around how you actually work, with soundproofing for calls, the lighting your eyes need, and the door that closes when the day demands it.
Lighting controls, automated shades, and Sonos speakers throughout, all routed to a hidden equipment rack so the tech stays out of sight and your living rooms stay clean.
The cost has come down enough that this is less of a stretch than it used to be, and the comfort of warm floors in winter is hard to undo.
Underpinned foundations and raised ceilings when the game demands it, with the flooring, hoop, and sightlines worked out before a single wall goes up.
Drawn with you and built to your specifications, with Shaker styling, integrated lighting, and the storage your real life actually needs, not the generic version.
Specific people, hobbies, and routines drive the plan, whether that’s a mudroom for the dogs, a reading nook for your kid, or a craft room for you.
Tell us what’s on your list. We’ll figure out how to weave it into the rest of the build.
Our network
Matched to your taste, budget, and the kind of home you want to build.
Architecture & Design
What we have is a deep network of architects and civil engineers across Chester County. We’ll match you with the right partner based on your taste, budget, and the kind of home you want to build.
The McComsey difference
Three things make a McComsey custom home different from the competition.
We’re licensed real estate agents through Cheska Realty. Before you commit to a piece of land, we evaluate zoning, setbacks, easements, septic feasibility, utility access, and driveway permitting. On one project, we caught a missing PennDOT driveway permit on a state highway during plan review. The client’s own civil engineer had missed it.
If the math says buying an existing home and renovating it makes more sense than building new, you’ll hear that from us first. We’ll walk you through the soft costs most builders gloss over before you sign anything, so the budget you sign is the budget you live with.
The earlier we catch a problem, the less it costs you. We know our trade partners and what they need to do their best work. We know what each township will and won’t approve. We bring all of that to your project before the first concrete is poured.

About a year of pre-construction (lot evaluation, civil engineering, septic, well, driveway, architectural plans, permits) before we break ground. From there, build time is typically 12 to 18 months depending on size and complexity.
Civil engineering, architectural fees, sewer or well or septic installation, driveway, stormwater management, PennDOT permits if your driveway is on a state highway, and electrical service upgrades. Soft costs can run $100,000 or more before construction begins. We map every one of them out before you sign anything.
Yes. We’re licensed real estate agents through Cheska Realty. We evaluate buildability before you commit, including zoning, setbacks, easements, septic feasibility, utility access, and driveway permitting.

Bring them. We’ll review them and flag any issues we see. The earlier we catch a problem, the less it costs you.
That’s one of the first questions we’ll answer with you. Sometimes building is the right call. Sometimes a serious renovation gets you most of what you want at a fraction of the cost and timeline. We’ll be honest with you about which one your situation calls for.
