If you bought a house in Round Rock built after about 1998, there’s a good chance your backyard came with a 10-by-10 or 12-by-12 concrete slab off the back door and nothing else. Here’s why, and the project that turns it into the room you’ll use most.
Why builders pour small slabs
Production builders price homes to compete on the base model. A patio is an easy place to cut: pour the minimum that satisfies the plan, leave the rest as sod, and let the buyer decide later. Multiply that by the thousands of homes in Teravista, Forest Creek, Behrens Ranch, Paloma Lake, Siena, Stone Canyon and Chandler Creek, and you get a city of backyards waiting for “later.”
What “later” usually looks like
Most Round Rock homeowners get to the backyard three to seven years after moving in. By then they know exactly what’s wrong with it: the slab is too small for a table and a grill, the afternoon sun makes it unusable from May to September, and the mosquitoes make it unusable after dark the rest of the year.
The three-step project
- Extend the slab. Widen it to the width of the house, or at least to the width of the cover you actually want. Slope it away from the house, place footings where the cover’s posts will go, and finish it plain, colored or stamped. See decks and concrete.
- Cover it with insulated aluminum. Attached below the second-floor windows, spanning the new slab with few posts, in a wood-grain finish that matches the trim. The insulated panel is what keeps the space cooler than a shingle roof would. See aluminum patio covers.
- Add the things that make it a room. A ceiling fan or two, recessed lights, an outlet, and screens if you’re near a creek or greenbelt. Wired during the build, not afterward. See screen rooms.
What it costs and how long it takes
For a typical two-story Round Rock home, the three steps together commonly land in the mid five figures depending on size and finishes; the cover is the largest line, the slab and electrical are smaller. HOA approval and the city permit take two to five weeks; the build itself takes a few days once materials arrive. Our cost guide has ranges.
The mistakes to avoid
- Covering only the existing slab. The cover ends up too small to live under, and extending later costs more.
- Skipping the fan. Shade without air movement isn’t enough in July.
- Skipping conduit. Adding lights after the cover is up means surface wiring or opening the roof.
- Building without a permit or HOA approval. It shows up at sale time.
