Who this plan suits
This plan suits households that want four bedrooms upstairs and a connected living area downstairs, with an office for working from home. It needs a lot that fits the 41'-8" × 36'-1" footprint plus setbacks and a driveway to the attached garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story house, 4 bedrooms, 2.5 baths, ground floor open kitchen, dining and family room in one space, office, powder room; upstairs 4 bedrooms, attached 2-car garage, front porch, about 2,500 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 is a 4 bedroom open floor plan house plan?
It is a home design with four bedrooms where the main living spaces are combined rather than separated by walls. In this plan, the kitchen, dining area and family room share one ground-floor space, and all four bedrooms are upstairs.
What affects the lot and building cost for this plan?
The 41'-8" × 36'-1" footprint sets the minimum lot width and depth once setbacks are added. Cost drivers include the 2,480 sq ft of living space, the two stories, the attached 2-car garage, the front porch, and local labor, materials and foundation conditions.
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 then updated, and you can review the revised plan before you download it.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plan sheets. The DXF opens in CAD software for drafting and editing, and the IFC imports into BIM tools. Have a local architect or engineer check the plan against your site and building code before construction.
