This single-story plan fits four bedrooms and two baths into 1,690 square feet of living space, with the garage counted separately. The footprint measures 42'-8" × 49'-10". A front porch leads into an 11'-3" × 5'-5" foyer. Beyond it, a 10'-5" × 30'-4" living room runs alongside the 16'-10" × 7'-8" kitchen and an 11'-3" × 8'-10" dining area.
The bedrooms sit apart from the living zone. A 3'-7" × 25'-9" bedroom hall serves Bedroom 2 (10'-5" × 11'-3"), Bedroom 3 (8'-8" × 12'-7"), Bedroom 4 (8'-8" × 12'-9") and the 10'-5" × 5'-6" hall bath. The primary bedroom is 12'-7" × 11'-9", with a 6'-8" × 9'-8" bath and a 5'-6" × 9'-8" walk-in closet. The 2-car garage (16'-10" × 18'-2") is paired with a 6'-8" × 5'-6" mudroom and a 9'-9" × 5'-6" laundry.

Who this plan suits
This plan suits families or households that want four bedrooms on one level without a large footprint. It needs a lot that can take a 42'-8" × 49'-10" footprint plus driveway access to the garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story small house, 4 bedrooms, 2 baths, compact split layout, open kitchen and living, laundry, attached 2-car garage, front porch, about 1,650 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 small 4 bedroom house plans?
Small 4 bedroom house plans fit four sleeping rooms into a compact footprint, usually by keeping rooms efficient and limiting circulation space. This one provides 1,690 sq ft of living space on a single level, with two baths and an attached 2-car garage.
What affects the cost and lot requirements for this plan?
The footprint is 42'-8" × 49'-10", so the lot must fit that plus setbacks and a driveway to the garage. Cost depends on your region, foundation type, finishes and site conditions, so get local builder quotes before you commit.
Can I change this plan by chat?
Yes. You can ask for changes such as moving the garage to the other side, resizing a bedroom, or adapting the layout to a narrower or wider lot. The plan is regenerated with the updated room sizes.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with builders or your local permit office. The DXF opens in CAD software for drafting and edits, and the IFC imports into BIM tools such as Revit or ArchiCAD. Local code review and engineering are still needed before construction.
