This two-story semi-detached plan has a 19'-8" x 23'-7" footprint and 930 sq ft of living space, with 2 bedrooms and 1.5 baths. One long side is a party wall with no windows, so daylight comes from the front and rear. On the ground floor, the entry (5'-5" x 8'-6") leads to the living/dining room at 12'-3" x 12'-11". The kitchen, 10'-11" x 8'-4", is next to it, and a guest WC (5'-5" x 4'-1") completes the level.
A 6'-8" x 8'-4" stair rises to an 18'-1" x 3'-3" landing that serves every room upstairs. Bedroom 1 measures 12'-3" x 9'-4" and Bedroom 2 measures 10'-11" x 8'-4", the same width as the kitchen below it. The bath, 5'-5" x 9'-4", opens off the landing, so both bedrooms share it without crossing the other's space.
Layout highlights
- Living/dining room of 12'-3" x 12'-11" sits on the ground floor beside the kitchen.

Who this plan suits
This plan suits a couple, a small family or a first-time buyer who wants two bedrooms and a compact, efficient footprint. It needs a narrow lot with a shared boundary on one long side, with room for a 19'-8" x 23'-7" footprint.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Small two-story semi-detached house 6 m wide, party wall on one long side (no windows there): ground floor kitchen-living-dining, guest WC; upstairs 2 bedrooms and a bath, about 85 m² (915 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 small semi detached house plans?
Small semi detached house plans describe a home that shares one wall with a neighboring house and stays compact. This plan shares a windowless party wall on one long side. It provides 930 sq ft of living space over two levels.
What affects building cost and lot fit for this plan?
The 19'-8" x 23'-7" footprint and two stacked levels keep the roof and foundation area small. The party wall must meet local fire and sound rules, and the lot needs a shared boundary on one long side. Site conditions, finishes and local labor rates will drive the final cost.
Can I change this plan by chat?
Yes. You can ask for changes in chat, such as moving rooms, resizing bedrooms, adding a garage on a chosen side or adjusting the plan to a different lot width. The layout is then updated to match your request.
How do I use the PDF, DXF and IFC files?
The PDF is for review, sharing and permit discussions. The DXF opens in CAD software for drafting and edits, and the IFC imports into BIM tools for coordination. Your architect or engineer should check the files against local codes before construction.
