This story-and-a-half plan provides 2,070 square feet of living space across two levels, not counting the garage. The footprint measures 57'-5" × 32'-2". From the front porch, the foyer (6'-4" × 7'-4") opens toward the great room, which measures 14'-11" × 20'-10" and holds the fireplace. The kitchen (17'-0" × 9'-0") and dining area (10'-0" × 9'-0") sit alongside it, so cooking, meals and seating share one connected space.
The main-floor primary suite includes a 7'-10" × 11'-1" bath and a 7'-10" × 5'-5" walk-in closet. The plan also has a mudroom (7'-10" × 6'-4"), a laundry room and an attached 2-car garage. Upstairs, the stair leads to an upper hall, a 10'-11" × 19'-10" loft, Bedroom 2 (10'-0" × 12'-3"), Bedroom 3 (10'-11" × 10'-0") and a shared bath.

Who this plan suits
This plan suits households that want the primary suite on the main floor, with two bedrooms and a loft upstairs for children, guests or a home office. It needs a lot that can fit a 57'-5" × 32'-2" footprint plus driveway access to the attached 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 mountain house, 3 bedrooms, 2.5 baths, great room with fireplace, kitchen, dining, mudroom, main-floor primary suite; 2 bedrooms and a loft upstairs, attached 2-car garage, front porch, about 2,100 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 3 bedroom mountain house plans?
They are home designs with three bedrooms that use mountain-style features, such as a front porch, a fireplace in the main living space and a story-and-a-half form. This plan has 2,070 square feet of living space, 3 bedrooms and 2.5 baths, with the primary suite on the main floor.
What affects the cost of building this plan and the lot it needs?
Cost depends mainly on your site, foundation type, local labor and materials, and the finishes you choose. The footprint is 57'-5" × 32'-2", so check setbacks and slope, and allow room for the garage driveway.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as moving the garage to the other side, adjusting room sizes or fitting a narrower lot. The layout is then updated to match your request.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with builders or contractors. The DXF opens in CAD software for 2D drafting and edits, and the IFC imports into BIM tools for 3D coordination. Have a local professional check the plan against your site and building code before construction.
