This single-story L-shaped plan offers 1,850 sq ft of living space, not counting the garage, on a footprint of 61'-0" × 42'-0". One wing holds the three bedrooms and two baths. The other holds the open living areas. The two wings meet at right angles and wrap around a back patio in the corner of the L.
From the foyer (10'-0" × 6'-4"), the plan opens to the great room (12'-3" × 31'-0"), with the dining area (12'-3" × 8'-8") and kitchen (8'-6" × 18'-2") alongside it. A pantry, laundry and mudroom sit between the kitchen and the 2-car garage (17'-6" × 21'-5"), so groceries and laundry stay on one short route. A 27'-8" bedroom hall leads to the primary suite and two secondary bedrooms, away from the main living space.
Layout highlights
- Great room runs 12'-3" × 31'-0" and connects directly to dining and kitchen.
- Primary suite: 10'-4" × 16'-0" bedroom, 4'-5" × 12'-7" walk-in closet, 6'-0" × 12'-7" bath.
- Bedrooms 2 and 3 measure 8'-6" × 15'-3" and 8'-2" × 15'-3", sharing a 6'-3" × 6'-4" hall bath.
- Mudroom, laundry (each 8'-8" × 6'-6") and a 8'-8" × 4'-5" pantry sit beside the garage.
- Front porch and a back patio in the inside corner of the L.

Who this plan suits
This plan suits households who want one-level living with the bedrooms separated from the living areas. It needs a lot at least 61 feet wide with enough depth for the 42-foot footprint, ideally with the back yard facing the patio corner.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story L-shaped house: bedroom wing (3 bedrooms, 2 baths) at right angles to the living wing (open kitchen, dining, great room), laundry, 2-car garage, back patio in the corner of the L, about 1,900 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 L shaped house plans?
An L-shaped house plan arranges two wings at right angles instead of one rectangle. Here, the bedrooms form one wing and the kitchen, dining and great room form the other. The inside corner creates a sheltered outdoor space, which in this plan is the back patio.
What affects the lot and building cost of this plan?
The 61'-0" × 42'-0" footprint sets the minimum lot width and depth, plus required setbacks. The L shape has more exterior wall and roof corners than a rectangle of the same area, which can add to framing and roofing work. Local labor, materials, foundation type and finishes will drive the final cost more than the layout alone.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing or adding rooms, moving the garage to the other side, or fitting a narrower lot. The plan updates to match, and you can keep refining it until the layout works for you.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plan with builders or family. The DXF opens in CAD software for drafting and measuring. The IFC opens in BIM tools for 3D coordination. Have a local architect or engineer review the plan before applying for permits.
