Explore this service →How a design-build remodel works
The reason remodels turn into horror stories is a broken hand-off: you hire a designer, then a separate contractor bids the drawings, then nobody owns the number or the schedule. Design-build fixes that — the people who design your project are the people who price it and build it. Here’s exactly what to expect, and roughly how long each step takes.
We come to your home, look at the space, and talk through what you actually want to change and roughly what you want to spend. You leave with an honest budget range — before anyone asks you to sign anything.
Our designer develops the plan, 3D layouts, and material selections with you — cabinets, tile, counters, fixtures — until the drawings match the way you live. You approve a fixed-price proposal with no surprises baked in.
We pull the permits, order long-lead materials, and build the real schedule. A pre-construction walkthrough sets expectations: where the crew parks, how we protect your floors, and which days matter.
One lead carpenter runs your job start to finish and you get a weekly schedule update. We dust-wall the work zone, protect the paths, and clean up every day — you keep living in the house.
We walk the finished project with you, build a punch list of anything that isn’t perfect, and close it out fast. Nothing is “done” until you agree it’s done.
You get a written workmanship warranty and a real number to call. Settling, a sticky drawer, a caulk line — we come back and make it right.
Financing
A kitchen, an addition, or a whole-home project is a $40k–$300k decision, and most homeowners would rather keep their savings working than write one big check. Qualified homeowners finance the project with fixed monthly payments through our lending partner — apply in minutes, and we’ll frame the design to a monthly number that actually fits, not just a total.
Service area
From the older homes of Brookside and Prairie Village to new builds in Overland Park and Lee’s Summit — we know how these houses are put together, what’s behind the plaster, and how to build without wrecking the character of the street. Local designers, local crews, subs we’ve trusted for years, and one point of contact from consultation to the day we hand you the keys.
Book a consultationOur crews, our trucks
When a Cornerstone Builders truck pulls up, you get our lead carpenter and crews we’ve built with for years — plus licensed subs we schedule and supervise. Same faces every day, one person accountable, across the Kansas City metro.
The team
Owner & Lead Designer
Class A General Contractor · 21 years in design-build
Daniel started Cornerstone after two decades of watching remodels go sideways at the hand-off between the designer and the builder. His whole model is design-build under one roof: the person who dreams up your project is the person who prices it and stands behind the number. He still runs the first consultation on most projects himself — and he’d rather talk you out of a bad idea than sell you a good-looking mistake.
Design Director
Kitchen & bath designer · 14 years · selections lead
Sara runs the design studio and the selections process — the part where a remodel either comes together or falls apart. She’s the one who turns a Pinterest board and a budget into drawings you can actually build, and who keeps cabinets, tile, and counters arriving in the right order so the schedule holds. Homeowners tend to describe her as the person who finally made the decisions feel manageable.
Production Manager & Lead Carpenter
Lead carpenter · 18 years on the tools
Marcus runs the crews and the job sites, which means he’s the reason a Cornerstone project stays clean, on schedule, and communicative. He assigns one lead carpenter to own your job start to finish — the same face every day — and he’s a stickler about dust walls, floor protection, and cleaning up before the crew leaves. It’s your house, and he treats it like it.
A word from the owner
I started Cornerstone after two decades of watching projects go sideways at the hand-off between the designer, the builder, and the subs. Here, one team owns your project — the person who prices it is the person who stands behind the number, from the first sketch to the punch list.
When you call Cornerstone Builders, you reach a local, family-run team — not a call center. Watch a quick hello, then book with someone you've already met.

Reviews
“We were terrified of a kitchen remodel — every friend had a nightmare story. Cornerstone gave us a fixed price up front, one lead carpenter we saw every day, and a weekly schedule. They opened a load-bearing wall and it still finished on time. It’s the room the whole family lives in now.”
“The design process is what sold us — Sara turned our vague ideas into real drawings and a budget that didn’t move. Our primary bath is genuinely a spa now, and the waterproofing and ventilation they kept talking about mean it still looks brand new. Worth every dollar.”
“They added a primary suite onto our house and you honestly cannot tell where the old house stops. Same brick, same rooflines, seamless. One team from the first sketch to the final walkthrough, and they came back to fix a settling crack a year later without a fuss. We’d hire them again tomorrow.”
FAQ
It starts with a free consultation — we walk the project, listen to what you actually want, and talk honest budget ranges on the spot. Then you get a written, itemized proposal: scope, materials allowances, timeline, and a fixed price. Not a one-line number that doubles later. If you’re comparing bids, we’ll even tell you what to look for in the other guys’ proposals — missing line items are where “low bids” hide.
Yes — licensed, insured, and bonded, and we carry both liability and workers’ comp, which protects you if anyone gets hurt on your property. We pull every permit and schedule every inspection ourselves; it’s part of the job, not an extra. A contractor who asks the homeowner to pull the permit is asking you to carry his risk — that’s the biggest red flag in this trade.
Here’s the honest answer: surprises exist — that’s construction. What we control is how they’re handled. You get a written schedule before we start, a fixed price for the defined scope, and any change gets priced and signed off in writing before the work happens — never invoiced as a surprise after. You’ll know where your project stands every week, from one person whose name you know.
You coordinate nobody. As your general contractor we run the whole job — our crews plus our licensed plumbing, electrical, and HVAC subs, all scheduled, supervised, and held to the same standard. One contract, one schedule, one person to call. That’s the entire point of hiring a GC instead of juggling five trades yourself.
Kansas City and the surrounding metro on both sides of the state line — Overland Park, Leawood, Prairie Village, Olathe, Lee’s Summit, Mission Hills, and the towns between. Local crews and local subs we’ve worked with for years. Not sure if you’re in our area? Call and we’ll tell you straight.
Yes. A kitchen, an addition, or a whole-home renovation is a $30k–$300k decision, and qualified homeowners can finance it from around $250/mo with $0 down — apply in minutes with our lending partner and we handle the build. We’ll also help you sequence a bigger vision into phases if that fits the budget better. Either way, you see the real numbers before anything starts.
