This two-story modern plan has 2,700 square feet of living space across two levels, not counting the attached garage. The footprint measures 40'-4" × 47'-3". A front porch opens to an 11'-7" × 5'-5" foyer, and a 21'-7" × 4'-2" ground hall leads back to the stair. The 2-car garage, 21'-7" × 17'-6", connects through a mudroom (4'-5" × 11'-1") and a laundry (4'-5" × 10'-8"), so coats and groceries stay near the entry.
The main living space is a 16'-10" × 22'-9" living room beside an 11'-5" × 14'-3" dining area and a 9'-4" × 18'-4" kitchen with a 9'-4" × 4'-1" pantry. A 6'-8" × 15'-7" office and a powder room finish the ground floor. Upstairs, the stair lands on a 10'-9" × 12'-5" hall that serves all four bedrooms. The primary bedroom is 16'-2" × 12'-5" and has a 13'-7" × 7'-4" ensuite and a 7'-4" × 9'-4" walk-in closet.

Who this plan suits
This plan suits families who want four bedrooms on one floor, plus a home office and a mudroom entry from the garage. It needs a lot that fits the 40'-4" × 47'-3" footprint plus setbacks, with the 2-car garage and front porch facing the street.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story modern house, 4 bedrooms, 3.5 baths, ground floor open kitchen, dining, living, office, powder room, laundry; upstairs 4 bedrooms including primary suite, attached 2-car garage, front porch, about 2,700 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 4 bedroom modern house plans?
They are home designs with four bedrooms and a contemporary layout, usually open living areas and simple rooflines. This version has 2,700 sq ft of living space on two levels, with all four bedrooms upstairs and the kitchen, dining, living room and office on the ground floor.
What affects the cost and lot requirements for this plan?
The 40'-4" × 47'-3" footprint, two stories and attached 2-car garage set the lot size and the foundation and roof scope. Cost also depends on your local labor, finishes, site conditions and structural requirements, so get local builder quotes before you commit.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing or moving rooms, switching the garage to the other side, or fitting a narrower or wider lot. The layout is then regenerated so rooms and circulation stay consistent.
How do I use the PDF, DXF and IFC files?
The PDF is for review, printing and sharing with your builder or contractor. The DXF opens in CAD software for drafting and detailing, and the IFC imports into BIM tools such as Revit or ArchiCAD. Have a licensed local professional review the plans before permit submission.
