Home Addition Contractor
Your family outgrew the house, but you love the street, the schools, and the neighbors. GM Tile Designs is a family-owned home addition contractor in The Woodlands, TX, and we build the extra room, the bigger primary suite, or the in-law space you need without the cost and stress of moving. Skilled craftsmen are on site for every job, the estimate is in writing before we break ground, and one accountable crew carries your project from permit to final walk-through.
Add the space instead of buying a new house
Moving is expensive and slow. Agent fees, a new mortgage rate, a higher tax bill, and the hunt for a home that still needs work add up fast. For a lot of families around The Woodlands, the smarter move is to stay put and grow the house you already own. A well-built addition gives you the square footage you need and adds real value to a home in a neighborhood you already like.
We build additions for the reasons people actually call us. A new baby means a bedroom and a second bath. Aging parents move in and need a private suite on the ground floor. A remote job needs a quiet, finished office. The kids need a real living room instead of a crowded one. We sit down, listen to how you live, and design the addition around that, not around a template.
Because we are a full general contractor, you get one company for the whole build. We frame it, we run the trades, and we finish it. You are not hiring a framer, then chasing a tile setter, then begging an electrician to show up. Uriel Gutierrez and his brothers Uzziel and Ulises Jr. are taking on more of a leadership role, backed by their father and founder Ulises, whose decades in the trade taught the family that a single accountable crew is what keeps a project on schedule and on budget. The sons run the jobs, so the family answers the phone and stays accountable, while skilled craftsmen do the build.
Additions we build across Montgomery and Harris counties
We keep our additions focused on the projects families ask for most, so the same hands build every part in house, day in and day out.
Room additions
A bump-out for a larger kitchen, a new family room, a sunroom, or a first-floor bedroom. We tie the new roofline, siding, and floor height into the existing house so the addition looks original, not bolted on. The new space matches the home you already love.
Second-story and primary-suite additions
When the lot is tight, the room to grow is up. We add second-story space and oversized primary suites with a spa-style bath, a walk-in closet, and the light you have been missing. Ranges vary widely by size and finish, and we put real numbers in your written estimate before any work starts. Pair it with a custom bathroom remodel and the suite feels like a retreat.
Garage conversions
Turning a garage into a heated, cooled, and finished room is one of the fastest ways to add living space without changing your footprint. It works for a game room, a home gym, a fifth bedroom, or a rental-ready suite. We insulate it, finish it, and make it feel like part of the house instead of a parking spot.
In-law and guest suites
A private bedroom, full bath, and sometimes a small kitchenette give parents or guests room of their own. We design these for comfort and easy access, with the finishes you want and the privacy everyone needs. It is one of our fastest-growing requests as families bring relatives closer to home.
We build all of these from our home base in Magnolia out across The Woodlands and into Memorial, with the same crew and the same written estimate no matter where you live.
Every trade your addition needs, under one roof
An addition is not one job. It is a dozen jobs that have to happen in the right order. The advantage of hiring a family general contractor is that we self-perform the trades that matter most, so the quality stays consistent from the slab to the paint.
- Slab, framing, and a roofline that ties into your existing roof so it sheds water and looks original.
- Tile, stone, and masonry from our flagship craft. Our tile and stone work is the same skill behind the Chick-fil-A build-out we tiled in Tomball.
- New flooring in hardwood, tile, or epoxy that matches or complements the rest of the house.
- A kitchen or wet bar in the new space, plus patios and covered outdoor areas through our kitchen and outdoor living team.
- Interior and exterior painting so the addition blends in and the whole exterior matches.
One crew, one point of contact, one written estimate. That is how a small family company keeps its reputation across Montgomery County and into Harris County.
Permits, timeline, and what to expect in Montgomery County
A real addition needs permits, and that is a good thing. Permitting protects you. It means an inspector checks the work, the structure stays sound, and the value holds up when you sell. In Montgomery County, the county typically permits and inspects additions outside city limits, while homes inside a city follow that city's process, and most neighborhoods around The Woodlands also run an HOA review for anything that changes the exterior.
We handle that paperwork as part of the job. We pull the permits, schedule the inspections, and keep the build to code so you are not stuck deciphering county forms on a weekend. You stay informed, but you do not have to chase anyone.
On timeline, a straightforward room addition or garage conversion often runs several weeks, while a second-story or large primary suite can run a couple of months once you finish design and permitting. We give you a firm schedule with your written estimate, protect the rest of your home during construction, and keep the site clean every evening. We carry insurance, and a Gutierrez walks the finished addition with you before we ask you to sign off. Get started in Magnolia, The Woodlands, or anywhere in our service area.
