A 1,729-square-foot modern plan built on a 42-foot infill lot in San Antonio, with the primary suite on the ground floor, three more bedrooms upstairs, and a 226-square-foot private roof deck reached by an interior stair.
The street elevation is a carport canopy running the full width of the house, with the upper volume set back above it — grey lap siding on one face, a wood-plank accent panel on the other, and a darker siding below. The wood is deliberately a small quantity: enough to give the elevation something warm at the front door, not enough to move the budget. Roof forms are low-slope sheds with deep flat overhangs, which is what lets a two-storey house sit on a 42-foot lot without the massing turning into a wall, and the whole envelope is documented on its own thermal envelope sheet with the wall and ceiling areas scheduled sheet-by-sheet.
You come in through a 115-square-foot entry with the main stair on your left and the living, dining and kitchen run straight ahead — 191, 144 and 174 square feet, no walls between them. The living end has a linear fireplace on the outside wall; the kitchen end has an island that seats four and a gas cooktop. The back wall opens onto a 258-square-foot covered deck, 26'-6" long, which faces the parking side of the lot rather than the street — on an infill lot that is where the usable outdoor space actually is.
The primary suite is on the ground floor behind the kitchen: 163 square feet, a 62-square-foot bath with twin lavatories and a walk-in shower, and a 43-square-foot closet. That one decision is what makes this plan work three different ways — a family that wants the parents downstairs, a multigenerational household, or an owner who rents the upstairs. Upstairs holds three more bedrooms, two of them with walk-in closets, and a 50-square-foot bath. A 32-square-foot powder room downstairs keeps guests out of the bedroom wing entirely.
Parking is a covered two-car carport off the rear street, so the cars sit under a roof without a garage door dominating an elevation. Storage is a 25-square-foot gypsum-lined space under the stair, the laundry is its own 63-square-foot room, and there is a 46-square-foot patio off the back in addition to the covered deck. The roof deck is reached by the interior stair, and the sections sheet shows exactly how the stair, the deck and the envelope stack up.
We didn't just draw this house — we built it. This is a permitted, constructed project, not a concept: every dimension on these sheets was checked against what actually got framed, and the field revisions from construction are already incorporated into the set you'll receive. Photographs of the finished house are being added to this page.

Ground: entry, living, dining, kitchen, primary suite, toilet, laundry, storage, covered deck, patio. First: three bedrooms, bath, three closets, hallway, stair to the roof deck.

Read this before you buy — it saves everyone a phone call.
These are architectural drawings. Your build will also need a foundation and structural design engineered for your specific soil and site, and MEP drawings if your jurisdiction requires them. Local code review and permit stamping by a professional licensed in your state are your responsibility. We can point you toward what to ask for, and we can do this work directly for projects in the San Antonio area.
Yes. We drew it, so we can modify it — moving walls, flipping the garage, adjusting the footprint, changing the roof. Send us what you want changed and we'll quote it. On the CAD Unlimited + PDF option, adapting the design to what you want is part of what you're buying. If you'd rather have your own designer make changes, any CAD option gives them the editable files.
That depends on the option you buy. The single-build tiers licence one house on one lot. The unlimited-build tiers licence you to build the design as many times as you want, on as many lots as you want, with no further payment. Either licence is yours alone and cannot be resold or transferred.
The PDF is the finished drawing set, print-ready, and it is all most people need. The CAD option adds the editable DWG files on top of the PDF, so you or your own designer can change the drawings directly. Both come in single-build and unlimited-build versions.
Codes vary by jurisdiction, and these drawings were prepared to Texas requirements. Have your local building department or a licensed professional in your area review the set before you pull a permit.
That depends entirely on your lot, your market, and your finish level. We'll give you the square footage breakdown you need to get real bids, but we don't publish a cost-to-build number we can't stand behind.
Once the files have been accessed, no. That's standard across the industry — a delivered plan set can't be returned. That's why the free sample sheets exist: look at the drawing quality before you buy.
Immediately after payment your account is unlocked and the full set is available for download. You can re-download any time.
