This two-story plan has 3,900 square feet of living space, not counting the garage, on a footprint of 52'-10" × 45'-11". It has six bedrooms and 4.5 baths. A guest suite (9'-0" × 14'-4") with a guest bath sits on the ground floor, and five bedrooms are upstairs. The 3-car garage (18'-4" × 27'-0") opens into a 19'-2" × 5'-2" mudroom, which keeps shoes and bags out of the main rooms.

The kitchen (20'-11" × 10'-11") has an island and a pantry. It sits between the dining room (13'-7" × 10'-11") and the 15'-4" × 25'-9" family room. A homework room is also on the ground floor, along with a powder room. Upstairs, a 33'-1" hall serves the primary suite, four more bedrooms, a laundry room and a 13'-9" × 24'-5" playroom. A front porch marks the entry.

Who this plan suits

This plan suits households that need many bedrooms, a place for homework and play, and a guest or multigenerational room on the ground floor. It needs a lot wide enough for the 52'-10" footprint plus setbacks, with garage access from the street or drive.

How this plan was made

It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story house, 6 bedrooms, 4 baths, ground floor guest suite, kitchen with large island, family room, dining, homework room, mudroom; upstairs 5 bedrooms and laundry, attached 3-car garage, front porch, about 3,800 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 makes a good house plan for a large family?

Large families usually need enough bedrooms, a private bedroom on the ground floor, and a clear route from the garage to the house. This plan has six bedrooms, a mudroom beside the 3-car garage, a homework room and an upstairs laundry.

What affects the cost and lot needs of this plan?

The 3,900 sq ft of living space across two levels, the 3-car garage and the front porch are the main drivers of cost. The footprint is 52'-10" × 45'-11", so your lot width, setbacks, soil and local labor rates decide the final figure. A local builder should price it.

Can I change this plan by chat?

Yes. You can describe changes in chat, such as moving the garage to the other side, resizing the family room, changing a bedroom count or fitting a narrower lot. The layout is regenerated with the new room sizes.

How do I use the PDF, DXF and IFC files?

The PDF is for reading and sharing the drawings. The DXF opens in CAD software for editing or tracing, and the IFC opens in BIM tools for 3D review. Your builder or designer should check them against local code before construction.
