This single-story plan provides 1,360 sq ft of living space (garage not included) on a footprint of 56'-9" × 31'-10". The front door opens to an 8'-2" × 6'-4" foyer. From there the 12'-9" × 20'-6" living room connects directly to the 10'-9" × 9'-0" dining area and the 8'-2" × 16'-10" kitchen, so cooking, eating and sitting share one open zone.
The three bedrooms sit off a 13'-1" × 8'-2" hall. The primary bedroom, 11'-7" × 11'-11", has a 7'-10" × 4'-9" walk-in closet and a 6'-4" × 8'-2" bath. Bedrooms 2 and 3 measure 11'-1" × 9'-0" and 10'-4" × 9'-0" and share the 7'-10" × 6'-10" hall bath. The 8'-2" × 5'-10" laundry and the attached 12'-11" × 29'-10" garage complete the plan.

Who this plan suits
This plan suits small families, couples who want a guest room or office, and downsizers who prefer one level with no stairs. It needs a lot at least about 57 ft wide to fit the 56'-9" footprint, plus setbacks required locally.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story house, 3 bedrooms, 2 baths, open kitchen, dining and living, laundry, attached 2-car garage, about 1,400 sq ft of living space (garage not included).” 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 1400 sq ft 3 bedroom house plans?
They are compact single-family layouts that fit three bedrooms and two baths into roughly 1,400 sq ft of heated living space. This version measures 1,360 sq ft of living area, not counting the garage. It keeps the shared rooms open and the bedrooms off a short hall.
What affects the lot size and building cost of this plan?
The 56'-9" × 31'-10" single-story footprint spreads the foundation and roof over one level, which affects cost more than the room count does. Lot width, local setbacks, soil, foundation type and finish choices also drive the total. Get quotes from local builders for your site.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing or moving rooms, switching the garage to the other side, or narrowing the plan for a tighter lot. The layout is regenerated so room sizes and connections stay consistent.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the layout and sharing it with others. The DXF opens in CAD software for drafting and measuring, and the IFC loads into BIM tools. Have a licensed architect or engineer review and stamp the plans for your site before applying for permits.
