This two-story semi detached plan has 1,360 sq ft of living space, 3 bedrooms and 2.5 baths on a footprint of 24'-7" × 27'-7". The entry (5'-10" × 10'-0") sits next to the stair (5'-9" × 10'-0"). The guest WC (4'-2" × 6'-8") and utility room (6'-0" × 6'-8") are kept close to the circulation. The ground floor then opens to the kitchen (10'-8" × 9'-1"), dining area (10'-8" × 9'-0") and living room (11'-11" × 15'-3") facing the garden.
Upstairs, a 15'-3" × 4'-6" landing connects the primary bedroom (15'-3" × 10'-4") and its ensuite (7'-4" × 5'-9"), Bedroom 2 (11'-3" × 10'-0"), Bedroom 3 (7'-4" × 9'-1") and the family bathroom (5'-2" × 10'-0"). One long side is a shared party wall with no windows, so daylight comes from the front and garden ends of the house.
Layout highlights
- Kitchen (10'-8" × 9'-1") and dining (10'-8" × 9'-0") sit side by side in one open space.
- Living room measures 11'-11" × 15'-3" and sits at the garden end of the ground floor.
- Guest WC (4'-2" × 6'-8") and utility room (6'-0" × 6'-8") keep daily tasks off the living area.
- Primary bedroom (15'-3" × 10'-4") has its own ensuite of 7'-4" × 5'-9".
- Bedroom 2 (11'-3" × 10'-0") and Bedroom 3 (7'-4" × 9'-1") share a 5'-2" × 10'-0" bathroom.

Who this plan suits
This plan suits families or couples who want three bedrooms and a separate utility room in a compact, attached home. It needs a narrow lot that can hold a 24'-7" × 27'-7" footprint, with the party wall built along one boundary.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story semi-detached house (one half of a pair), 7.5 m wide, party wall on one long side (no windows there): ground floor entry, guest WC, open kitchen, dining and living to the garden, utility room; upstairs 3 bedrooms, bath and ensuite, about 125 m² (1,345 sq ft).” 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 semi detached house plans?
Semi detached house plans describe one half of a pair of homes that share a common wall along one side. That wall carries no windows, so the layout puts rooms and glazing on the front, rear and open side. This makes a narrower lot workable without giving up three bedrooms.
What affects the lot and cost of building this plan?
The main drivers are the 24'-7" × 27'-7" footprint, the shared wall with the neighboring home, and the two floors of 1,360 sq ft of living space in total. Local soil, foundation type, finishes and the party wall fire rating will shape the final cost. Check setbacks and the neighbor's boundary agreement before you build.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing rooms, moving the stair, mirroring the plan so the party wall switches sides, or fitting a different lot width. Keep in mind that a garage is not part of this version, so adding one would change the footprint.
How do I use the PDF, DXF and IFC files?
The PDF is for reading and printing the plans and room sizes. The DXF opens in CAD software for drafting and site layout, and the IFC loads into BIM tools for coordination with engineers. Local code review and engineering sign-off are still needed before construction.
