This single-story plan fits a 39'-8" × 52'-6" footprint, so it stays within a 40 ft wide lot while providing 1,620 sq ft of living space, not counting the garage. The 2-car garage, 18'-0" × 20'-10", faces the front, and a front porch leads into a 9'-4" × 7'-0" foyer.
Past the foyer, the living room (11'-1" × 23'-5"), dining area (8'-8" × 12'-11") and kitchen (8'-8" × 16'-0") run together as one open space. A 4'-5" × 10'-5" mudroom and a 4'-5" × 10'-0" laundry support everyday traffic from the garage. Bedrooms 2 and 3, both about 10'-8" wide, open off a 6'-2" × 21'-11" hall shared with the hall bath. The primary suite measures 14'-7" × 11'-9" and includes an 8'-8" × 8'-8" bath and a 5'-6" × 8'-8" walk-in closet.
Layout highlights
- Open living (11'-1" × 23'-5"), dining and kitchen (8'-8" × 16'-0") share one continuous space.
- Primary suite is 14'-7" × 11'-9" with an 8'-8" × 8'-8" bath and walk-in closet.
- Bedrooms 2 and 3 are 10'-8" × 10'-5" and 10'-8" × 10'-4", off a 21'-11" hall.
- Mudroom (4'-5" × 10'-5") and laundry (4'-5" × 10'-0") sit between the garage and the living areas.
- Footprint of 39'-8" × 52'-6" holds a front 2-car garage of 18'-0" × 20'-10".

Who this plan suits
This plan suits households that want three bedrooms and two baths on one level, with a front-loading garage and no stairs. It needs a lot at least 40 ft wide, plus room for setbacks and about 52'-6" of depth.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story house at most 40 ft wide: 3 bedrooms, 2 baths, open kitchen, dining and living, laundry, 2-car garage at the front, about 1,550 sq ft of living space.” An AI architect drafted the room program, a layout solver placed every wall and door, and the plan was checked automatically for room sizes, circulation and daylight. The same project produced the PDF sheets, layered DXF, IFC model and 3D model you can download above.
Frequently asked questions
What are 40 ft wide house plans?
They are house plans designed so the full width of the building, including the garage, stays at or under about 40 ft. This one measures 39'-8" across, which makes it workable on narrow and infill lots. Setbacks vary by municipality, so the lot itself usually needs to be wider than the house.
What affects the cost and lot requirements for this plan?
The 39'-8" × 52'-6" footprint sets the minimum lot size, and local side and front setbacks decide how much extra width you need. Cost drivers include foundation type, roof complexity, finish level and regional labor rates. A single-story layout spreads the foundation and roof over more area than a two-story plan of similar size.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing a bedroom, moving the garage to the other side, or adjusting the plan for a narrower or wider lot. The layout is updated and the room sizes are recalculated. Check the revised dimensions against your setbacks before you build.
How do I use the PDF, DXF and IFC files?
The PDF is for reading and sharing the plan, including with your builder or permit office. The DXF opens in most CAD programs for drafting and site layout. The IFC file imports into BIM software so you can review the model in 3D or continue detailing. Local code review and engineering are still required before construction.
