This two-story plan has 3,590 square feet of living space, not counting the garage, on a footprint of 45'-7" × 54'-2". A front porch leads to a 12'-7" × 7'-0" foyer. The living room (21'-2" × 19'-7") anchors the main level, with the kitchen (12'-1" × 16'-10") and dining room (8'-8" × 16'-10") alongside and a 5'-6" × 9'-8" pantry.
A mudroom (13'-3" × 5'-6") and laundry (9'-4" × 5'-6") sit on level one with the 3-car garage (22'-1" × 26'-5"). The office (7'-4" × 14'-11"), a guest bedroom (9'-4" × 13'-7") and a guest bath complete the main floor. Upstairs, the primary bedroom (19'-0" × 13'-7") has a 13'-7" × 6'-6" walk-in closet and a primary bath. Three more bedrooms open off the upper hall, and a 27'-0" × 10'-4" media loft adds shared space.

Who this plan suits
This plan suits households that want five bedrooms, a home office and a three-bay garage in one two-story house. It needs a lot that fits the 45'-7" × 54'-2" 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, 5 bedrooms, 4 baths, open kitchen, dining and living, laundry, office, mudroom, attached 3-car garage, front porch, about 3,500 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 3500 sq ft house plan include?
A 3500 sq ft house plan usually describes a large two-story home with four to five bedrooms and several baths. This version measures 3,590 sq ft of living space, excluding the 3-car garage, and has 5 bedrooms, 4 baths, an office, a mudroom and a media loft.
What affects the cost and lot requirements of this plan?
The 45'-7" × 54'-2" footprint, two levels, four baths and a 3-car garage are the main drivers of construction scope. Your lot needs room for that footprint, setbacks and a driveway, and local labor, materials and soil conditions will set the final cost.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as moving the garage to another side, resizing rooms, adding or removing a bedroom, or fitting a narrower lot. The plan is regenerated with the new layout and updated room sizes.
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 lenders. The DXF opens in CAD software for drafting and site layout, and the IFC imports into BIM tools for coordination with an architect or engineer.
