This two-story plan fits 1,830 square feet of living space into a 30'-10" × 30'-10" square footprint, with no garage. A front porch leads to the foyer. The ground floor holds the living room (23'-0" × 10'-11"), dining room (10'-8" × 9'-1"), kitchen (14'-7" × 8'-0"), laundry and a powder room. A 17'-10" hall links these rooms, and the stair rises from the same floor.
Upstairs, the primary bedroom (11'-11" × 15'-3") has a walk-in closet (7'-6" × 7'-4") and an ensuite bath (5'-9" × 13'-3"). Bedroom 2 (8'-8" × 15'-3") and Bedroom 3 (14'-7" × 8'-0") share a bath (7'-6" × 7'-6"). All three bedrooms open off the 22'-9" upper hall. Putting every bedroom on one floor keeps sleeping space apart from the kitchen and living areas below.

Who this plan suits
This plan suits households that want three bedrooms and 2.5 baths in a compact, easy-to-frame square volume. It needs a lot wide enough for the 30'-10" × 30'-10" footprint plus the front porch and side setbacks. It has no garage, so parking would need to be planned separately.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story square-footprint house, 3 bedrooms, 2.5 baths, ground floor kitchen, dining, living, powder room, laundry; upstairs 3 bedrooms, front porch, about 1,900 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 square house plans?
Square house plans use a footprint with roughly equal width and depth. This one measures 30'-10" × 30'-10". A square shape keeps the exterior wall length short for the floor area it encloses, and it stacks two levels neatly. The trade-off is that rooms are arranged around a central stair and hall rather than in a long open run.
What affects the lot and building cost of this plan?
The 30'-10" square footprint, the front porch and the two-story height set the lot size and foundation. Cost depends mainly on your region, finishes, and the structure and mechanical systems you choose. Because the plan has no garage, parking or a detached structure would be a separate item. A local builder should price it from the final drawings.
Can I change this plan by chat?
Yes. You can ask for changes in plain language, such as resizing or moving rooms, adding a garage on a chosen side, or fitting a narrower or wider lot. The plan is regenerated with updated room sizes and areas. Check the revised drawings against your local setbacks and codes before building.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plan with a builder, lender or neighbor. The DXF opens in CAD software for editing or site layout. The IFC is a BIM format that imports into tools such as Revit or ArchiCAD for coordination with engineers. A licensed professional should review the files before permit submission.
