This two-story plan offers 2,510 square feet of living space, not counting the garage, within a 55'-5" × 30'-10" footprint. The ground floor puts the kitchen with island (18'-4" × 9'-0"), the dining area (8'-10" × 19'-6") and the living room (18'-4" × 19'-6") along one open run with large glazing. A foyer and mudroom connect the entry porch and the 2-car garage (17'-10" × 19'-6") to the main rooms. The office (7'-4" × 19'-6"), powder room and laundry sit off the main space.
The stair rises from the ground floor to an upper hall (18'-4" × 5'-2") that serves all four bedrooms. The primary bedroom (18'-4" × 13'-11") has a primary bath (8'-4" × 11'-3") and a walk-in closet (11'-3" × 6'-4"). Bedrooms 2 and 3 are each about 15 feet long and share the hall bath (8'-4" × 7'-10"). Bedroom 4 measures 11'-3" × 12'-9".

Who this plan suits
This plan suits families who want shared living space downstairs and bedrooms grouped upstairs, with a dedicated office. It needs a lot at least about 55'-5" wide for the footprint, plus setbacks, with garage access from the front.
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 baths, ground floor open kitchen with island, dining and living as one room with large glazing, office, powder room, laundry; upstairs primary suite and 3 bedrooms, attached 2-car garage, about 2,600 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 open concept modern house plans?
They combine the kitchen, dining and living areas into one connected space instead of separate walled rooms, and usually pair that with large windows and simple rooflines. In this plan the three spaces run along the ground floor, with the office and utility rooms kept apart.
What affects the lot and cost of building this plan?
The 55'-5" × 30'-10" footprint sets the minimum lot width, and the two-story form keeps the foundation and roof area smaller than a single-level plan of the same size. Large glazing, the island kitchen, three bathrooms' worth of plumbing and the garage are the main cost drivers. Local codes, soil and finishes will change the final figure.
Can I change this plan by chat?
Yes. You can ask for changes such as moving the garage to the other side, resizing or adding rooms, or fitting a narrower lot. The plan is updated and the room sizes are recalculated so you can review the revised layout.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with contractors or a permit office. The DXF opens in CAD software for editing and drafting, and the IFC loads into BIM tools for coordination. A licensed architect or engineer should review the files before you submit for permits.
