This two-story plan has 2,800 sq ft of living space, 4 bedrooms and 3.5 baths on a 50'-6" × 43'-8" footprint. The garage is not counted in the living area. A front porch leads into an 8'-2" × 10'-0" foyer. The living room (16'-9" × 20'-10"), dining room (8'-8" × 15'-0") and kitchen (10'-1" × 20'-6") share one open zone, with an 8'-8" × 5'-1" pantry beside the kitchen.
Daily entry runs from the attached 3-car garage (14'-3" × 41'-8") into a 7'-6" × 11'-7" mudroom. The laundry, a powder room and a 6'-8" × 15'-7" office are also on the main level. Upstairs, a 33'-11" × 5'-6" hall connects the primary suite, three more bedrooms and a hall bath. The primary bedroom is 21'-11" × 10'-4" with a 6'-2" × 10'-4" walk-in closet and a 14'-3" × 6'-0" bath. Bedroom 2 has its own 5'-5" × 8'-4" bath.

Who this plan suits
This plan suits families who want four bedrooms upstairs, a main-level office and a mudroom for a 3-car garage. It needs a lot that fits the 50'-6" × 43'-8" footprint plus setbacks, and a garage front or side that works with your street.
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, open kitchen, dining and living, laundry, office, mudroom, attached 3-car garage, front porch, about 2,800 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 are 2800 sq ft house plans?
They are home designs with about 2,800 sq ft of heated living space, usually 4 bedrooms and 3 to 4 baths. This plan measures 2,800 sq ft over two levels, and the 3-car garage is not included in that figure.
What affects the lot and building cost of this plan?
The 50'-6" × 43'-8" footprint sets the minimum lot width and depth once setbacks are added. Cost depends on your region, foundation type, finishes and the long 3-car garage (14'-3" × 41'-8"), so get local builder quotes.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing rooms, moving the garage to the other side, or fitting a narrower lot. The layout is regenerated so the rooms still connect, and you can review the new sizes before downloading.
How do I use the PDF, DXF and IFC files?
The PDF is for review and sharing with builders or permit offices. DXF opens in CAD tools for drafting and edits, and IFC imports into BIM software such as Revit or ArchiCAD. Have a local engineer or architect check the plan against your code and site.
