Who this plan suits
This plan suits households that want the primary bedroom on the main floor and two bedrooms set apart upstairs, such as empty nesters with visiting family or families with younger children. It needs a lot that fits the 47'-3" × 41'-0" footprint plus room for the front porch and driveway to the 2-car garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Story-and-a-half house, 3 bedrooms, 2.5 baths, main-floor primary suite, kitchen, great room, dining; 2 bedrooms and a bath under the roof upstairs, attached 2-car garage, front porch, about 2,000 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 story and a half house plans?
A story and a half house has its main living areas and often the primary bedroom on the first floor, with additional rooms under the roof on a partial upper level. This plan follows that pattern: the primary suite, kitchen, great room and dining are on level 1, and two bedrooms and a bath are upstairs.
What affects the lot requirements and building cost of this plan?
The 47'-3" × 41'-0" footprint sets the minimum lot size, and the garage and porch add to the area you need for setbacks and the driveway. Cost depends on your region, foundation type, roof framing over the upper level and the finishes you choose, so get local bids before you commit.
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, and the plan is updated to match. Changes affect the layout and measured sizes, so review the revised room dimensions before you use the plan.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the drawings with your builder or lender. The DXF opens in most CAD programs for 2D editing, and the IFC imports into BIM software for 3D work. Have a local engineer or architect check the plan against your site and building code before construction.
