This single-storey plan places two mirrored dwellings side by side on a 66'-3" × 33'-6" footprint, joined by a single party wall. Together they provide 1,960 sq ft of living space, 4 bedrooms and 2 bathrooms. There is no garage. Each home has its own entry porch and a 6'-8" × 7'-8" entry that opens to an 8'-10" × 7'-2" hall.
Inside each dwelling, the kitchen (9'-4" × 12'-11"), dining room (9'-4" × 10'-0") and living room (13'-1" × 13'-7") form one open area. A covered alfresco extends the living space outdoors. Bedroom 1 (11'-11" × 10'-0") and Bedroom 2 (9'-5" × 10'-0") are served by the hall, which also reaches the bathroom (6'-8" × 7'-2") and the laundry (5'-6" × 7'-2"). The second dwelling repeats the same arrangement in reverse.

Who this plan suits
This plan suits owners who want two separate households on one site, such as a family with a relative, or an owner-occupier with a rental unit. It needs a lot that can take a 66'-3" × 33'-6" footprint plus setbacks, with room for parking elsewhere on the site.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-storey dual occupancy home: two mirrored side-by-side dwellings sharing one party wall, each with its own entry, 2 bedrooms, bathroom, open kitchen, dining and living, laundry and covered alfresco; about 95 m² (1,020 sq ft) per dwelling, 190 m² (2,045 sq ft) of living space in total.” 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 dual occupancy house plans?
Dual occupancy house plans describe two separate dwellings on one lot. Each has its own entry, kitchen, bathroom and living space. In this plan the two homes are mirrored and share one party wall, so each household keeps its own front door and alfresco.
What affects the lot and cost of building this plan?
The main factors are the 66'-3" × 33'-6" footprint, local setbacks and zoning rules for two dwellings on one lot, and the cost of separate utility connections for each home. The single-storey form and shared party wall keep the structure simple. Soil conditions, slope and local requirements also affect the final cost.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as adding a room, resizing a bedroom, moving the entries or fitting a narrower lot width. The plan is then regenerated with the new layout. You can ask for a garage, but it would change the footprint.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with family, lenders or a builder. The DXF opens in most CAD programs for drafting and site layout. The IFC can be imported into BIM software to check the model. Have a local designer or engineer confirm the plans meet your local code before you submit for a permit.
