Shop Houses in Houston, TX

Shop houses are barndominiums where the shop is the point: a big clear-span bay for trucks, a tractor, a boat or a business, with a home attached under the same roof. On acreage around Houston, from the pine country in Montgomery County to the prairie in Waller and Fort Bend, a shop house lets owners keep equipment out of the weather and close to the back door.

Sizing the bay

We start with what has to fit. Overhead door height and width come from the tallest vehicle, often an RV, a bass boat on a trailer or a tractor with a loader. Depth comes from the longest one plus room to walk around it and a workbench. The living side is then laid out around that bay, not the other way around.

Separating shop and home

A shop is dusty, noisy and often unconditioned, while the home is sealed and cooled. We put a mudroom, laundry or storage room between them, use an insulated wall and door, and give the shop its own air conditioning or ventilation plan so the house's system is not fighting Houston heat through a roll-up door.

Concrete and drainage

Shop slabs take heavier loads and need to stay level. On expansive clay like the Lake Charles soils of the Houston prairie, which crack deep when dry and swell when wet, slab design matters more under a loaded shop floor. We also slope the shop apron so rainwater runs away from the bay doors.

Power and water

Welders, compressors and lifts need electrical capacity planned from the start. Utility runs, a hose bib and a shop sink are easier to place before the slab is poured. HomeGuide puts bringing power from the road at about $5 to $15 per square foot overhead or $10 to $25 underground, so the distance from the road to your shop matters.

Who builds shop houses

Shop houses suit people whose work or hobbies need space: contractors with trucks and trailers, families with boats for Lake Conroe or the Gulf, ranchers with tractors and hay equipment, and hobbyists who restore cars. The common thread is wanting the shop steps from the kitchen instead of across town.

Wells, septic and the shop apron

A shop house usually sits on enough land for its own well and septic system. In unincorporated Harris County a private well generally needs an approval letter from the County Engineer, including a diagram of its distance from any septic system within 100 feet, and the well permit itself comes from the Harris-Galveston Subsidence District. A driveway that crosses a roadside ditch in the county right-of-way needs its own permit. We place the well, the septic field and the shop drive together so trucks and trailers never cross the drain field.

Shop doors and flood lines

Roll-up doors sit at slab level, so they are the first opening water reaches. In the Harris County 100-year floodplain, sealed drawings have to show the garage threshold elevation along with the finished floor, and in Santa Fe the lowest floor in a special flood hazard area must be at least 12 inches above the base flood elevation. The shop floor height comes from your flood data, not from the lot next door.
