This 3 bedroom 1 bath house plan fits 1,100 square feet of living space on one level, within a footprint of 37'-5" × 31'-6". A front porch leads to the living room, which measures 13'-7" × 14'-9" and is the largest room in the house. The kitchen (7'-8" × 13'-7") sits next to the dining area (11'-1" × 8'-8"), so food travels a short way from counter to table.
A hall measuring 14'-8" × 6'-2" connects the bedrooms and the shared bathroom (6'-4" × 6'-2"). The primary bedroom is 10'-4" × 13'-7". Bedroom 2 is 10'-4" × 9'-0" and Bedroom 3 is 10'-9" × 9'-0". The laundry (11'-1" × 4'-6") is its own room rather than a closet. The plan has no garage, so all 1,100 square feet are living area.

Who this plan suits
This plan suits small households, first-time builders, and anyone who wants three bedrooms with a single bathroom on one level. It needs a lot wide and deep enough for a 37'-5" × 31'-6" footprint plus setbacks and a front porch.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story house, 3 bedrooms, 1 bath, kitchen with dining, living room, laundry, front porch, about 1,100 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 is a 3 bedroom 1 bath house plan?
It is a home layout with three bedrooms that share one full bathroom. This version is a single-story plan with 1,100 square feet of living space. Having one bathroom keeps the footprint compact and reduces plumbing.
What affects the cost of building this plan?
The main drivers are your local labor and material rates, foundation type, soil conditions, and the finishes you choose. The 37'-5" × 31'-6" footprint and single level keep the structure simple, and the plumbing is concentrated around one bathroom, the kitchen, and the laundry. Get local quotes before you commit to a budget.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing rooms, adding a garage on a chosen side, or adjusting the plan for a narrower lot. The layout is then updated to match your request.
How do I use the PDF, DXF, and IFC files?
The PDF is for reviewing the plan and sharing it with builders or permit offices. The DXF opens in CAD software for drafting and edits. The IFC loads into BIM tools so you can inspect the model in 3D and coordinate with other disciplines.
