Semi Detached House Plans
Semi-detached plans show one half of a pair of houses that share a party wall. The shared side is drawn as a real party wall (a hatched REI 90 fire wall with no windows or doors), so the rooms take their light from the front, the rear and the open side. Building in pairs cuts land and building cost per home. Full duplex plans with both halves are in the duplex collection.
This collection has 7 plans from 930 to 2,074 sq ft of living space, 2 with an attached garage and 4 on two stories. Every plan is a real measured drawing: walls, doors and windows are placed, room sizes add up to the total, and you can download the PDF plan set, a DXF for AutoCAD and an IFC model at no cost. To change one, open it in Plan Chat and describe the change; the rest of the house stays as it is.

Frequently asked questions
How big are these semi detached house plans?
The plans in this collection range from 930 to 2,074 sq ft of living space (garage, porches and patios not included). The median is 1,714 sq ft. Each plan page lists every room with its inside dimensions.
Are the dimensions real?
Yes. Each plan is a measured model, not a picture: the room table is computed from the walls, and the same model produces the PDF, DXF, IFC and 3D files. They are concept plans, so a local designer or engineer still has to adapt them to your site and code before you build.
Can I change one of these semi detached house plans?
Open the plan in Plan Chat and describe what you want, for example "add a home office", "move the garage to the left" or "fit a 45 ft wide lot". Plan Chat changes only what you ask for and keeps every version. Changes use credits from a paid plan.
