This two-story plan has 2,940 square feet of living space, not counting the garage, on a footprint of 41'-0" × 48'-7". The ground floor holds the shared rooms. The foyer (8'-6" × 8'-8") leads toward the family room (16'-6" × 19'-0"), with the kitchen (7'-4" × 18'-2"), pantry and dining room (8'-10" × 13'-7") alongside. An office (8'-4" × 8'-8") and a guest suite (13'-7" × 8'-8") with its own 9'-8" × 5'-10" bath complete the main level, and a powder room serves guests.
A mudroom (14'-11" × 4'-6") connects the 3-car garage (22'-1" × 26'-5") to the main floor. Upstairs, the primary bedroom (12'-3" × 16'-4") opens to a primary bath (11'-11" × 9'-0") and closet (8'-4" × 9'-0"). Bedroom 2 (13'-7" × 8'-8") and Bedroom 3 (8'-0" × 16'-4") share the floor with a hall bath (8'-4" × 5'-6"), a laundry room (8'-4" × 5'-6") and a 17'-2" × 24'-7" bonus room, all reached from the upper hall.

Who this plan suits
This plan suits households that want a guest or multigenerational bedroom on the ground floor and the family bedrooms upstairs, with room for a home office. It needs a lot that fits the 41'-0" × 48'-7" footprint plus setbacks and driveway access to the garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story house, 4 bedrooms, 3.5 baths, ground floor guest suite, open kitchen, dining, family room, office; upstairs primary suite, 2 bedrooms, bonus room, laundry, attached 3-car garage, about 3,000 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 does a 3000 sq ft 4 bedroom house plan usually include?
Plans at this size typically combine open living areas with a primary suite, secondary bedrooms and flexible space. This one has 2,940 sq ft of living area, 4 bedrooms and 3.5 baths, plus an office, a bonus room and a 3-car garage that is not counted in the living area.
What affects the cost and lot requirements of this plan?
The two-story form keeps the footprint to 41'-0" × 48'-7", which helps on narrower lots, but the three-car garage, five bathrooms and powder room, and the large bonus room add to framing and plumbing scope. Local codes, soil, finishes and site work will drive the final cost, so get bids from local builders.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as swapping the office for another bedroom, moving the garage to the other side, or fitting a narrower lot. The layout is regenerated so room sizes and connections are updated together.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the floor plans and sharing them with family, builders or designers. The DXF opens in CAD software for further drafting, and the IFC imports into BIM tools. Have a licensed professional review the plans before permitting or construction.
