This single-story plan has 1,140 square feet of living space, not counting the garage, on a footprint of 35'-1" × 41'-4". A front porch leads to the 12'-3" × 18'-10" living room. The living room opens to the 10'-0" × 9'-9" kitchen and the 10'-0" × 8'-8" dining area, so cooking, eating and sitting share one connected space.
An 11'-9" × 6'-2" hall connects the three bedrooms to the shared rooms. The primary bedroom measures 10'-0" × 13'-7", Bedroom 2 is 8'-6" × 13'-7", and Bedroom 3 is 9'-4" × 10'-4". The 8'-6" × 6'-2" full bath serves the bedrooms, and a 4'-9" × 6'-2" half bath handles guests. A 7'-0" × 6'-2" laundry and a 13'-11" × 13'-7" attached one-car garage complete the plan.

Who this plan suits
This plan suits small households, first-time builders and downsizers who want three bedrooms and one level of living in about 1,140 square feet. It needs a lot that fits the 35'-1" × 41'-4" footprint plus setbacks and a driveway to the one-car garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story house, 3 bedrooms, 1.5 baths, open kitchen and living, dining, laundry, attached 1-car garage, front porch, about 1,300 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 3 bedroom 1.5 bath house plans?
They describe homes with three bedrooms, one full bathroom and one half bathroom. This version is a single-story layout with 1,140 square feet of living space. The half bath keeps a second full bathroom out of the budget while still giving guests a separate option.
What affects the cost and lot requirements of this plan?
The footprint is 35'-1" × 41'-4", so the lot must fit that size plus local setbacks. Cost depends mainly on your region, foundation type, finishes and site work. The attached garage and front porch add to the footprint and should be included in your estimate.
Can I change this plan by chat?
Yes. You can ask for changes such as different room sizes, the garage on the other side, or a layout adjusted to a narrower or wider lot. The plan is updated to match your request, and you can review the new layout before you use it.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the layout, sharing it and discussing it with a builder or designer. The DXF opens in CAD software for drafting and editing. The IFC imports into BIM tools so you can work with the model in 3D.
