This 1.5 story plan has 2,280 sq ft of living space, not counting the garage, within a 54'-2" × 37'-1" footprint. The front porch opens to a 5'-5" × 11'-11" foyer. Beyond it, the 16'-2" × 22'-0" great room joins the 6'-10" × 18'-2" dining area and the 10'-9" × 16'-10" kitchen with pantry, so cooking, eating and sitting share one open space.
The primary suite is on the main floor: a 15'-4" × 11'-11" bedroom with an 8'-10" × 6'-8" walk-in closet and a 7'-0" × 11'-11" ensuite. The 10'-9" × 5'-6" laundry, the powder room and the 17'-2" × 22'-9" two-car garage are grouped off the hall. Upstairs, the stair lands in an 8'-4" × 13'-9" hall that serves Bedroom 2 (8'-4" × 13'-11"), Bedroom 3 (10'-4" × 10'-8"), a shared bath and a 10'-4" × 18'-2" loft.

Who this plan suits
This plan suits households that want the primary bedroom on the main floor, with two bedrooms and a loft kept upstairs for children, guests or an office. It needs a lot at least wide and deep enough for the 54'-2" × 37'-1" footprint plus local setbacks.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “1.5-story house: main floor with the primary suite (walk-in closet, ensuite), open kitchen, dining and great room, laundry, powder room, 2-car garage; smaller upper floor with 2 bedrooms, a bath and a loft. About 2,300 sq ft of living space.” 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 1.5 story house plans?
A 1.5 story house plan puts the main living areas and often the primary suite on the first floor, with a smaller second floor above. In this plan, the upper level holds two bedrooms, a bath and a loft, while the rest of the living space is on the main floor.
What affects the lot and building cost for this plan?
The 54'-2" × 37'-1" footprint sets the minimum lot size once setbacks are added. Cost drivers include the 2,280 sq ft of living space, the two-car garage, the front porch, the stair and the stacked bath and plumbing locations. Local labor, materials and site conditions also matter.
Can I change this plan by chat?
Yes. You can ask for changes such as resizing rooms, moving the garage to the other side, or fitting a narrower lot. The plan is regenerated so the rooms stay connected after each change.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with a builder or lender. The DXF opens in CAD software for drafting and edits, and the IFC imports into BIM tools such as Revit or ArchiCAD. Have a local engineer or architect check the plan against your site and building codes before construction.
