House Plans under 1000 Sq Ft

Plans under 1,000 sq ft are cottages, cabins, tiny houses and backyard ADUs. Most fit on a small or rear lot and are popular as rentals or for aging parents.

This collection has 104 plans from 310 to 997 sq ft of living space, 9 with an attached garage and 6 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 house plans under 1000 sq ft?

The plans in this collection range from 310 to 997 sq ft of living space (garage, porches and patios not included). The median is 704 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 house plans under 1000 sq ft?

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.
