Greatwood is a master-planned community where adding an ADU means something different than it does almost anywhere else in the Houston metro. The subdivisions here, most of them built after 1990, run on strict deed restrictions and HOA design reviews that control everything from roofline to driveway width, so the work is less about raw construction and more about getting the design approved the first time. We help homeowners in Greatwood plan detached ADUs, garage conversions, and room additions with honest pricing, written quotes, and a crew you can verify before they ever step onto your property. Call us at (940) 242-3207 to talk through what your lot can support.
Why Greatwood Homes Are Different
Greatwood’s housing stock is overwhelmingly brick-and-Hardie suburban tract homes on lots that are generous in the back but tight on the sides. That layout pushes most ADU projects toward rear-yard detached units or garage conversions, because the side-yard setbacks simply don’t leave room for a separate structure alongside the house. The two-story traditional style that dominates the neighborhood also matters: a detached ADU has to sit behind the primary structure without making the original home feel crowded out, which is a design and sight-line problem as much as a square-footage problem.
The climate is the other half of the equation. Greatwood gets hot, humid summers and heavy spring and fall rain. Any detached ADU we build here goes onto an elevated foundation with moisture-resistant materials at the base, hurricane-rated roof ties, and an HVAC system sized honestly for the heat, not just for the square footage. And because Greatwood has no municipal zoning, only private deed restrictions, the same plan that clears one street’s HOA can get rejected on the next block for a roofline detail. We handle that paperwork and design documentation up front, because it’s the part of a Greatwood project that actually determines whether the project happens at all.
Our Main Greatwood Services
Most homeowners in Greatwood reach out to us about one of three things: adding square footage to the main house, building a detached ADU in the backyard, or converting underused space inside the existing footprint. Here’s how each one works in Greatwood.
Home Addition Contractor in Greatwood
A home addition in Greatwood means working against the same deed restrictions that shape every other project here. Whether you’re extending the kitchen, adding a primary suite, or building out a sunroom, the HOA design review will look at the exterior elevation, the roofline, and the setback from your property line. We prepare those submissions as part of the build, so there are no surprises after framing starts. The climate matters here too: an addition needs to tie into your existing foundation properly and get an HVAC plan that handles August heat without overworking the system.

ADU Builders in Greatwood
A detached ADU in Greatwood usually lands in the rear yard, where the lot has room and the side setbacks don’t limit the footprint. The deed restrictions in many Greatwood subdivisions cap the unit’s height, dictate exterior materials that match the primary home, and sometimes limit the driveway approach. We’ve worked with homeowners through those reviews, and we’re fluent in the prefab ADU product lines that clear HOAs more easily, including Dvele and Plant Prefab, because their exterior packages are built to look intentional rather than temporary.

Room Addition Contractor in Greatwood
A room addition in Greatwood often means converting space that already exists but isn’t counted as living area, like a garage, a bonus room, or underused attic space. Because these projects usually don’t change the exterior footprint, the HOA review is simpler in some Greatwood subdivisions, though a garage conversion can still trip the design review if you change the driveway or the facade. We’ll tell you honestly whether your room addition will trigger a full design review or a lighter administrative approval before you commit to the build. Room Addition Contractor in Greatwood.

We give you a written price that locks all of that in before any work starts, so the number you sign off on is the number you pay unless you change the scope yourself.

FAQs About ADU Company in Greatwood
Yes, in nearly every Greatwood subdivision you’ll need design review approval from your HOA before you can build. Greatwood has no municipal zoning, but the private deed restrictions function like zoning, and they control size, placement, exterior appearance, and sometimes driveway access. We prepare the submission documents as part of the project and handle revisions if the board requests changes.
Most Greatwood HOA design reviews take 30 to 60 days from submission to decision, depending on the committee’s meeting schedule. That timeline is outside our control, but we sequence the build so foundation and site work begin immediately after approval, which keeps the total project time as short as possible. Call (940) 242-3207 and we’ll walk through the likely timeline for your specific section.
Sometimes, yes. A garage conversion that keeps the garage door in place and doesn’t change the exterior often receives lighter review or no review at all in some Greatwood sections, while converting the garage facade into a wall with windows will almost always trigger full design review. The answer depends on your specific HOA’s rules, and we’ll find that out before you spend money on plans. Call (940) 242-3207 for a free estimate.
