Modern 3-Bedroom Compact Small House Plan, 1150 sq ft, with 20’ x 31’ footprint only!
If you are concerned about eco-friendly living, or just want to build a small detached guest house at the back of your property, this compact small house design might be suitable for you.
This 3-bed small house plan has only 20′ x 31′ footprint and also potentially be built in modules. So the construction and maintenance costs can be significantly reduced, making this house super affordable.
General house specification:
- 1,150 sf 2-story structure
- 3 Beds + 1 Small Den
- 1.5 Baths⠀
- 20’-0” W x 31’-0” D
- Laundry / utility storage room
- Outdoor porches
- Attic spaces for future development
This small house plan is suitable for a very tight and small plot of land. You can also build this as an off-grid independent cabin or secondary unit / detached ADU / granny suite.
The original design comes with a slab foundation. You can also opt for either basement structure (with extra living space) or with a crawl space – depending on the existing site condition where you are planning to build.
Despite its tiny shape, this house has ample natural lights. The interior looks spacious due to its compact and efficient layout and its modern full-height windows.
We use natural material finishes with modern touch for the exterior, e.g. stucco / cement finish, stones, metal roof, wood slats or siding clapboard (optional) and black frame door windows.
