Helping Commerce City Homeowners Turn All That Square Footage Into Something Real

Why Commerce City Homeowners Choose Christie's

Because Every Commerce City Basement
Holds More Living Space Than You've Been Using

For more than 25 years, Christie’s has helped Commerce City homeowners stop staring at a concrete slab and start stepping into a lower level that actually changes how the whole house feels. The custom bar where Saturday nights finally have a home. The theater room your kids will never want to leave. The guest suite with a real en-suite bath, and a permitted egress window that makes it a legal bedroom on the appraisal. That is what makes basement finishing personal.

At Christie’s Design/Build Remodeling, we know what Reunion, Fronterra Village, and Turnberry gave you, a thousand square feet or more of uninterrupted slab, genuinely enough room for a bar, a theater, a gym, and a guest suite under one roof. We walk that concrete before we quote it, we flag moisture before it becomes a problem, and we handle every permit through Commerce City’s Community Development office so the finished square footage counts. From program-rich multi-room designs to the built-ins that make a space feel custom, we bring the full picture.

What Makes Basement Finishing & Remodeling Different In Commerce City

A Finished Commerce City Basement
Should Show Up On The Appraisal, Not Just Look Good

Basement finishing in Commerce City has a starting point most Denver-area markets genuinely can’t match, the master-planned communities in Reunion, Fronterra Village, and Turnberry delivered homes with 1,000 to 1,400 square feet of uninterrupted concrete slab, which means there’s real room for a custom wet bar, a home theater, an egress-compliant guest suite, and a gym without the layout feeling forced or compromised. That square footage also carries a practical question homeowners here ask early: will a finished basement show on the appraisal as a legal bedroom? At Christie’s Design/Build, we bring the egress window well conversation into the very first layout discussion, because a permitted bedroom addition is a concrete line item on an appraisal, and that matters when you’re building equity in this market. We walk Commerce City’s ePlans permit process, coordinate HOA architectural review for exterior window wells, and resolve any moisture at the slab before framing begins, so nothing surfaces mid-project that catches you off guard.

.01

Commerce City Homes, Master-Planned to Established

Commerce City basements in Reunion, Fronterra Village, and Turnberry are some of the most generous unfinished slabs in the metro, often 1,000 to 1,400 square feet of open concrete, which means the entire design conversation can focus on program richness rather than fighting for space.

.02

Columns, Mechanical Chases, and Slab Realities

Commerce City’s Reunion-era builds hand you a wide-open slab, but support columns, low ductwork runs, and the mechanical chase still shape every room boundary in ways that have to be solved together, not worked around.

.03

Prior Finishes That Need a Full Rethink

In Commerce City’s older neighborhoods near Quebec Parkway and Chambers Road, finishing a dated basement regularly uncovers builder-grade carpet laid directly on concrete, drop-tile ceilings, undersized egress windows, aging electrical panels, and moisture at the slab that all need to be fully resolved before any new framing or finishes can begin.

.04

Commerce City Family Life and Equity

Commerce City’s clay-heavy soils and freeze-thaw cycles make moisture at the foundation a real pre-construction conversation, not an afterthought. Vapor assessment and subfloor planning happen before framing begins, so your finished space stays comfortable through every Colorado season.

Commerce City, CO Neighborhoods

Your Commerce City Basement
Is a Full Floor Waiting to Happen

Commerce City’s master-planned communities, Reunion, Fronterra Village, Buffalo Highlands, and Turnberry, were built with something most homeowners haven’t fully reckoned with yet: 1,000 to 1,400 square feet of clean, uninterrupted concrete slab sitting untouched beneath the main floor. Basement finishing in Commerce City is a different conversation than most markets, because the footprint is genuinely large enough to hold a custom wet bar, a home theater, a guest suite with an egress-compliant bedroom, and a home gym all under one roof without crowding a single one. A family in Reunion might be weighing the stay-vs.-move decision and wants to know the finished space will show up on the appraisal as a legal bedroom, not just a nice room. At Christie’s Design/Build Remodeling, we look at your mechanical chase location, ceiling clearances, and how your household actually plans to live in the space before we put a single wall on paper. The neighborhoods below reflect the homes, and the homeowners making real equity decisions, that we work with here.

Turnberry

A Lower Level That Finally Earns Every Square Foot

Homes in Turnberry were built by KB Home with modern floor plans and energy-efficient systems, and most came with a generous unfinished basement that’s been waiting quietly since move-in day. That concrete slab is your opportunity: enough room to build a custom wet bar for weekend hosting, a home theater designed from the framing stage, and a guest suite with an egress window that shows up on the appraisal as a legal bedroom rather than just a bonus room. A basement finish here might also include a home gym, built-in shelving, and durable LVP flooring that handles Colorado’s seasons without complaint. The goal is a lower level that feels as intentional and connected as everything KB Home handed you upstairs.

Reunion

Turn Your Large Unfinished Basement Into The Multi-Room Space You Have Been Sitting On

Homes in Reunion were built with generous unfinished basements, often 1,000 square feet or more of clean concrete slab that’s been waiting since move-in day for someone to finally make a plan. That’s enough room for a custom wet bar anchoring a full entertaining zone, a dedicated home theater with proper acoustics, and an egress-compliant guest suite with its own en-suite bath, all under one roof without fighting for every inch. Because these homes reflect 2000s–2010s master-planned construction, the bones are solid and modern-code-ready, which means the conversation moves quickly to what you actually want rather than what the structure can handle. The finished space that comes out of a Reunion basement project isn’t just comfortable, it shows up on the appraisal the way it should.

Fronterra Village

The Basement Fronterra Village Homes Were Always Built to Have

In Fronterra Village, the homes built between 2002 and 2017 came with something most older neighborhoods never had, genuinely generous unfinished basements, clean concrete slabs ready to become whatever your family actually needs. The bones here are newer, which means the finishing conversation starts with design rather than problem-solving, turning that open footprint into a custom wet bar anchored to an entertaining space, a guest suite with an egress window and its own full bath, or a home theater built for the experience from the framing stage up. Homeowners here are deliberate about this investment, they want the finished space to show up on the appraisal and feel like it belongs to the home above it, not like a renovation someone bolted on later.

Buffalo Mesa

The Square Footage Is Already There, Let's Make It Count

Buffalo Mesa homes were built after 2000 on a plan that assumed families would eventually finish what the builder left behind, clean slabs, modern framing, and the kind of generous footprint that fits a wet bar, a guest suite, and a home gym without anyone having to compromise. That’s exactly what we hear from families here: plenty of room, just none of it finished yet. What most Buffalo Mesa homeowners are after is a lower level that earns its square footage with a real design, defined zones, thoughtful lighting, and finishes that feel like they belong to the rest of the home rather than a contractor’s afterthought.

Buffalo Run

The Space Below That's Ready to Work as Hard as You Do

Buffalo Run is a neighborhood where families settled in for the golf course and the breathing room, and the basement quietly became the most underused square footage in the house. Homes here across Villages at Buffalo Run West tend to have the slab, the ceiling clearance, and the footprint to support a real multi-zone finish, a custom bar, a proper guest suite, or a dedicated media room, without fighting for every linear foot. That’s exactly the kind of open canvas where Christie’s does its best work.

Our Commerce City Basement Finishing Process

The Basement Downstairs Is Ready to Become the Home Up Here

Finishing a basement in Commerce City comes with a genuinely different starting point than most of the metro, if your home is in Reunion, Fronterra Village, or Turnberry, you’re most likely sitting on 1,000 square feet or more of uninterrupted concrete slab with real room for a custom bar, a home theater, an egress-compliant guest suite, and a gym all under one roof, plus the equity logic of a legal bedroom showing up on your next appraisal. Our process moves your project through every phase, moisture assessment, space planning, Commerce City ePlans permitting, HOA review for any egress window wells, construction, and final walkthrough, so the finished lower level feels like a natural, well-planned part of the home you’ve been building equity in all along.

.01

Initial Consultation

We start by walking your unfinished Commerce City basement with you and taking an honest look at what’s actually down there, concrete slab, ceiling clearances, mechanical chase footprint, moisture conditions, and whether the layout can support the multi-room program you have in mind. Those details shape every design decision before a wall gets framed. From there, we build a plan that works around your home’s real structure and moves toward the bar, theater, guest suite, or gym you’ve been thinking about since you moved in.

.02

Planning & Budgeting

Every Commerce City basement finish starts with an honest conversation about the space you already have and everything you’ve been imagining it could be. We talk through your wishlist, the wet bar, the theater room, the guest suite, alongside what your home’s structure actually allows, including column placement, mechanical chase location, and whether egress makes sense for that spare bedroom count. The plan that comes out of that conversation is built around your specific home in Reunion or Fronterra Village, not a layout borrowed from anywhere else.

.03

Design & Layout Planning

Once we know how you want to use the space, we start designing the details of your finished Commerce City basement around that picture. Layout, ceiling treatments, lighting, custom millwork, and every zone, wet bar, home theater, guest suite, gym, gets planned with real intention and your appraisal goals in mind. The result is a lower level that feels connected to the home above it rather than like a finished room nobody planned for.

.04

Permitting & Preparation

Before construction begins, Christie’s handles the coordination that keeps your Commerce City basement project on track from the start. That means submitting through the city’s ePlans portal, pulling a separate plumbing permit for your bathroom, coordinating HOA architectural review for any exterior egress window wells, and lining up materials and trades in the right sequence. Getting all of that organized before the first crew arrives is what turns a well-designed plan into a build that actually moves.

.05

Construction

This is where your Commerce City basement starts becoming the space you’ve had in your head since you bought the house. Our crews work carefully through framing, insulation, drywall, flooring, carpentry, and finish work, keeping you informed at every phase so nothing feels like a surprise. Whether your project is built around a custom wet bar and home theater, a guest suite with an egress window, a dedicated gym, or all of it together, every phase is coordinated so the finished lower level comes together the way it was designed.

.06

Final Walk-Through

When construction is complete, we walk the finished basement with you and go through every detail together. We want it to feel exactly the way you pictured it, the bar ready for company, the guest suite genuinely comfortable, the theater room dark and dialed in, the gym yours from day one. The goal is a lower level that feels like a permanent, natural part of your Commerce City home the very first time your family steps into it.

What Commerce City Homeowners Want From Their Basement Finish

A Commerce City Basement That
Actually Shows Up On The Appraisal

What Commerce City homeowners want from a finished basement is shaped by the housing stock they bought into, large, open concrete-slab footprints in master-planned communities like Reunion and Fronterra Village that were always meant to become something more. The conversations here consistently land on program richness: a wet bar anchoring the entertaining zone, a home theater designed from the framing stage, and a permitted egress suite that adds a legal bedroom to the appraisal count. The goal is a lower level that works as hard as the rest of the home and proves it when it’s time to refinance or sell.

Egress Suites & Full Bathrooms

More Room For What Matters

Commerce City's Reunion-era homes sit on some of the most generous unfinished footprints in the metro, often 1,000 to 1,400 square feet of open concrete. A legal guest suite, a full bath, and a real entertaining zone can turn that slab into square footage your whole family genuinely counts on.

Multi-Room Layouts That Deliver

1,400 Square Feet, Fully Lived In

Reunion and Fronterra Village basements come with a mechanical chase, at least one support column, and ductwork that all need a home in the layout. Bringing those constraints into the design conversation before a single wall is framed means the finished space flows the way you imagined it, not around obstacles you discovered too late.

Custom Bars & Built-In Millwork

Every Room, Every Need

In Commerce City's larger floor plans, an unplanned basement fills back up with gear and overflow faster than you'd expect. Integrated built-ins, dedicated closets, and intentional shelving keep that contained so your bar, your theater, and your living zones stay exactly what you built them to be.

Home Theaters, Trim & Crafted Details

That Concrete Slab, Finally Finished

A custom bar with quartz counters and under-cabinet lighting hits different than a basement that just has drywall. Built-in media walls, coffered ceilings in the theater zone, and consistent trim details throughout are what make your Commerce City basement feel designed from the ground up, not just finished.

Slab-Ready Flooring That Performs

Designed For How You Live

Commerce City's clay-heavy soils mean moisture can migrate through a concrete slab long before you notice it, and your flooring choice has to account for that from the start. Waterproof LVP over a proper subfloor system handles Colorado's freeze-thaw swings and busy households without buckling, making it the floor that stays looking great through everything.

What To Consider When Finishing Your Basement In Commerce City

Live Beyond The
Unfinished Concrete

Your Commerce City basement is likely one of the largest blank canvases in the whole house, sometimes 1,000 square feet or more of uninterrupted slab just waiting. What shapes it from here are the decisions you make before framing begins: how moisture gets addressed, whether egress is planned in for a legal bedroom, and how the mechanical chase, permit process, and HOA review get sequenced so nothing surprises you mid-build.

What do you actually want to be doing down there on a Friday night?

It sounds simple, but this question shapes everything. A basement built around hosting feels different from one built around a home theater or a quiet home office, different lighting, different acoustics, different traffic flow. Before you talk layout, get honest about how your family spends evenings and weekends, because the best basement is the one you actually use, not the one that looked impressive in a photo.
There’s a meaningful difference between a space that functions like a guest room and one that legally counts as a bedroom on your appraisal. If aging parents, an adult child, or long-term guests are part of your picture, an egress-compliant window well isn’t optional, it’s what separates a bedroom from a finished room on every comp that follows. Think through who you’re designing for, and you’ll know whether that conversation needs to happen early.
Commerce City’s clay-heavy soil doesn’t announce itself; it shows up quietly as efflorescence on the walls or a smell you’ve learned to ignore. Framing over a moisture problem doesn’t make it disappear, it hides it until it’s a much bigger issue. Before you commit to a layout, spend time in the space after a heavy rain or a hard freeze, and be honest about what you see. Catching it at planning is a small item; catching it after drywall is not.
The kids using it as a playroom today are teenagers in a few years, and the guest suite you’re not sure you need right now might be the most-used room in the house when your parents need to stay longer. Open zones with defined purposes age better than a series of small closed rooms you can’t reconfigure. Think about the household you’re building toward, not just the one you have right now, it’s the kind of decision that pays off without a single renovation.

Commerce City Basement Finishing Frequently Asked Questions

Everything You're Asking Before You
Finish That Space Downstairs

Commerce City homeowners come to us with a starting point most families in the Denver metro would envy, a large, open concrete slab in Reunion, Fronterra Village, or Turnberry that’s been sitting untouched since the builder handed over the keys. The square footage is genuinely there: enough room for a custom wet bar, a home theater, a guest suite with its own bath, and a gym without bumping into one another. The question we hear most isn’t “can we do this?”, it’s “how do we make sure the bedroom actually counts on an appraisal?” These FAQs address what Commerce City homeowners most commonly ask before starting a basement finishing project with Christie’s Design/Build Remodeling.

Still Have Questions?
We're Here To Help.

Do I need a permit to finish my basement in Commerce City?

Yes, every time, no exceptions. Commerce City requires a building permit for any basement finishing work through the Community Development office. That means framing, electrical, insulation, drywall, and any bathroom work all require a permit pull and inspection sign-off. You’ll submit your plans electronically through the city’s ePlans system, and if you’re adding a bathroom, that triggers a separate plumbing permit as well. We know it feels like extra steps, but skipping permits is the one decision that genuinely comes back to hurt you at resale, un-permitted finished square footage doesn’t count on an appraisal, and buyers’ lenders catch it. We manage the entire permit workflow for you so nothing falls through the cracks.
It can, and in Commerce City, this is one of the most important questions to get right before you start. A finished basement adds real appraised value when the work is permitted, inspected, and meets code. A legal bedroom addition, which requires an egress-compliant window well, goes directly to your bedroom count, and bedroom count is one of the clearest lines on an appraisal report. That’s why we talk through egress early in every project, even when a guest suite wasn’t in the original plan. The ROI math on a permitted, legal bedroom in Reunion or Fronterra Village is one of the strongest cases for finishing your basement rather than shopping for a bigger house.
An egress window well is the code-required opening that makes a basement bedroom a legal bedroom, it gives someone a way out in an emergency and meets the IRC’s minimum opening size standards. In practice, that means cutting through your concrete foundation wall, installing a properly sized window and well liner outside, and often adding a drainage system to keep the well from collecting water. In Commerce City’s master-planned communities, HOAs in neighborhoods like Reunion may require an architectural review for exterior modifications before we break ground, we handle that submission as part of the project. It adds to the scope, but it’s the difference between a room that counts and a room that doesn’t.
Plan on roughly three to four months from a signed contract to a finished space you can actually use. The front end, design, plan development, and permit review with the City of Commerce City, typically runs three to six weeks. Once permits are in hand, construction runs six to twelve weeks depending on how many rooms and specialty features are in the program. A project with a custom wet bar, a guest suite bathroom with slab-core plumbing, and a home theater is on the longer end of that window. We’re honest about this timeline upfront because the worst surprise in a remodel is a delay you didn’t see coming.
That white chalky residue is efflorescence, mineral deposits left behind when moisture migrates through your concrete. It’s extremely common in Commerce City’s clay-heavy soil conditions, especially after a few years of freeze-thaw cycling. It’s not always a sign of serious structural damage, but it does tell us moisture is moving through the wall, and that has to be addressed before a single stud goes up. We walk every basement before we quote it specifically to identify this kind of issue. Framing over a moisture problem and finishing the walls is the one thing that turns a good project into a very expensive headache two or three years later.
Luxury vinyl plank, LVP, is the right call for most of your finished basement floor. It sits directly over concrete, handles the humidity swings Colorado goes through season to season, and doesn’t telegraph moisture the way hardwood will over time. Large-format LVP at a premium thickness looks genuinely high-end and holds up to real family use. For wet areas, your bathroom, around the bar, large-format tile is standard. Engineered hardwood is an option in low-moisture zones if you love the warmth of wood, but we’ll walk through the moisture picture in your specific basement before recommending it.
Yes, and this comes up constantly in Reunion-era homes where builders didn’t stub in plumbing beyond the basics. Adding a bathroom without existing rough-in means a plumber cores through your concrete slab to set the drain, then ties it into your existing system. It’s real sub-scope, it adds cost and a few days of work, but it’s completely doable and worth it. A finished basement without a bathroom is a space people tolerate. A finished basement with a full tile-surround bath is a space people actually want to live in. We bring the plumbing sub-contractor in during the planning phase so you understand exactly what that scope looks like before anything is finalized.
This is one of the first things we check on-site, because finished ceiling height in newer Commerce City construction isn’t always what you’d expect. Engineered joists, low-profile HVAC runs, and ductwork trunks can drop your finished height to seven feet or less in sections of the space, and IRC code requires at least seven feet of clearance in habitable rooms. The good news is that a well-planned basement design works with those constraints rather than fighting them. Dropped soffits become design elements framing a recessed lighting band. HVAC trunk lines get hidden in a coffered ceiling detail. We see this in almost every Reunion-area project, and there’s a right way to solve it that actually makes the space feel more finished, not less.
