Home Addition Contractor Windsor, CO
You like your street, your neighbors, and your commute. You just need one more bedroom, or a primary suite that isn’t down the hall from the kids. Instead of selling and starting over, add the space onto the house you already have. We design additions that match your home’s rooflines and finishes, so nobody can tell where the old house stops. And our nationally recognized, Chrysalis Award-winning team plans every detail before construction begins.
Stay in the Neighborhood You Love, Get the Space You Need
Running out of room in your Windsor home? Before you start touring houses and bidding against three other offers, look at what an addition could do.
An extra bedroom for a growing family. A main-floor suite for a parent moving in. A kitchen big enough for everyone who shows up at Thanksgiving. An addition gets you there without the moving truck.
We build additions that look like they were part of the original plans, not an afterthought stuck on the back.
When Your Home No Longer Fits Your Life
Been in your Windsor house a while? Still meaning to get to the upgrades you planned when you moved in? Maybe the kids moved out and a bedroom became a treadmill and a guest bed. Or maybe your family is growing and every room feels a little smaller each year. Either way, if the house doesn’t fit your life anymore, we can fix that.
Design a Home That Grows With You
Your house should change when your life does. Most people don’t need a new house. They need the one they have to catch up.
Whether you’re in a newer build in Water Valley or an older home closer to downtown, you don’t have to move to get more room. Add the bedroom, open up the wall between the kitchen and living room, build the space your household is actually short on.
Bedroom, office, playroom, in-law suite, whatever’s missing. Or pair it with a full remodel. Either way, we handle it.
What We Offer
Home additions and full renovations, built to fit your Windsor home and your actual budget, not a one-size-fits-all package.
Space for the Way You Live Now
A bedroom for a growing family, a main-floor suite for a parent moving in, a studio, gym or home office. Your addition is designed to match your home’s style inside and out, so it never reads as an add-on.
Better Function, Not Just More Square Footage
We often pair additions with kitchen and bathroom updates so the whole house works better together, not just the new part.
A Smart Investment
An addition pays you back twice: in resale value, and in not having to sell, move and start over. From a bump-out to a full second story, it adds real, lasting value to your home.
More Square Footage, More Resale Value
Finished square footage is one of the first things Windsor buyers look at. Adding on raises your home’s total living space and its value along with it.
5-Year Manufacturer's Warranty
An addition has to tie into your existing roof, foundation and systems perfectly, and we stand behind every connection. Your addition is covered by our 5-year workmanship warranty, plus the manufacturers’ warranties on the materials we install. Warranty calls are rare because everything is planned before we build, but if anything covered ever isn’t right, we’ll make it right.

The standout feature of this kitchen is the warm, rich wood center island paired with the matching natural accents, such as the custom plaster-style range hood and light oak flooring. Set against the crisp, full-height white backsplash and clean shaker cabinetry, these natural wood elements ground the space and bring effortless warmth, texture, and contrast to an otherwise bright, modern aesthetic.
This modern, transitional kitchen features contrast-toned cabinetry: deep navy lower cabinets paired with soft white upper cabinets with glass-front detailing. It is anchored by a warm white oak kitchen island and wide-plank hardwood floors, complemented by light quartz counter surfaces, a metallic range hood, a herringbone tile backsplash, and elegant brass hardware.
With light colored wood tones, a dreamy blue backdrop, tons of natural light, and a gorgeous vaulted ceiling, this masterpiece is warm, inviting, and entirely functional.
The rich, warm-wood open beams running across the new vaulted ceilings instantly draw the eye upward, giving the open-concept layout a sense of height, warmth, and character.

Why Choose Us?
Here’s what actually matters when you’re picking who builds your addition.
We've done this - a lot.
Second-story additions, kitchen bump-outs, full living space overhauls. We’ve spent years figuring out how to add real square footage without wasting an inch of it.
Built Around What You Actually Need
Every addition starts with your situation, whether that’s more natural light, a guest room with real privacy, or a main-floor suite for aging in place. No template, no default plan.
Worth What You Pay
We’re not the most expensive remodeler in Northern Colorado, and we’re not the cheapest. We believe we’re the best value. The lowest bid often ends up costing the most in the long run. With us, you get work that holds up, a fixed price before construction that doesn’t change as long as the scope stays the same, and a process that never leaves you guessing.
You'll Know What's Going On
Our client portal shows your timeline, budget, and progress photos, so you’re not waiting on a phone call to find out where things stand.
Craftsmanship That Actually Holds Up
Before your addition ever reaches construction, our designers and Preconstruction Manager complete the design, every selection, every drawing, every number and the full schedule. Then our own install team and hand-picked trade partners build it to tie seamlessly into the rest of your home, so the new space looks like it was always there.
Home Addition Investment
Every addition is different. Most of our home additions range from $175,000 to $750,000+, depending on size, whether it’s a bump-out or a second story, and the finishes you choose. We’ll talk through a realistic range early, and you’ll receive a fixed price after design that doesn’t change as long as the scope stays the same.

FAQ
How long does a home addition project typically take?
It depends on the size. A bump-out moves quickly, and a second-story addition takes longer. Because the design, selections, drawings and pricing are all complete before construction starts, the build moves efficiently, with no waiting on decisions halfway through. You’ll get a clear schedule after design, and you can see it anytime in your client portal.
Do I need a building permit for an addition in Windsor?
Yes. Additions require permits through the Town of Windsor, and some neighborhoods also have HOA design review. We handle the permits and inspections as part of the project.
How do you make sure the addition matches the rest of my home?
We match rooflines, siding, windows, and interior finishes to what’s already there, and you’ll see the full design in 3D before construction starts.
What should I consider before adding a second story?
Whether your foundation and existing walls can carry the extra weight, how the new stairs will affect your main floor, and what HOA or town height limits apply. We check all of that during design.
Will my HOA need to approve the addition?
In a lot of Windsor neighborhoods, yes. We’ll help you put together the drawings and material selections your HOA typically asks for so approval doesn’t stall the project.
Are there other ways to add space without a full addition?
Yes. Finishing a basement, converting part of a garage, or a smaller bump-out off the kitchen or primary bath can each add usable space without a full addition.
Does an addition add resale value?
Usually, especially when it adds a bedroom, a primary suite, or a bigger kitchen. The key is keeping the cost in line with what homes in your neighborhood sell for, and we’ll talk through that honestly.
Can I stay in my home during an addition?
Most of the time, yes. Much of the work happens outside the existing house until the tie-in. For larger projects that touch the kitchen or your only bathroom, we’ll plan around it with you.
