About this plan

A perfectly square twelve by twelve metre plan is efficient to build, simple to heat and easy to divide into well-proportioned rooms. This free plan fits a 12 × 12 metre footprint (about 39 × 39 feet) and gives 144 m² (1,550 sq ft) of enclosed floor space once the walls are in place. It includes three bedrooms and 2 bathrooms. Open it in the editor to move walls, swap furniture or walk through it in 3D.

Room-by-room layout

Bedroom 1 is 13.8 m², a practical size for a double bed and a wardrobe; bedroom 2 is 13.8 m², a practical size for a double bed and a wardrobe; bedroom 3 is 13.8 m², a practical size for a double bed and a wardrobe; bathroom 1 covers 11 m² with a toilet, a basin and a shower; bathroom 2 covers 13.8 m² with a toilet, a basin and a shower. The largest space is the living room at 52 m², and the smallest is the bathroom 1 at 11 m². Altogether the plan counts 7 doors, 8 windows and 88.5 m (290 ft) of wall, numbers you can read live in the editor's stats panel.

Design tips

Before you finalise this plan, keep a few habits in mind. Place the bathroom next to the kitchen or on a shared wall, so water pipes stay short and cheaper to install. Keep the entrance close to the living area so guests never have to cross the bedrooms to reach the sofa. Test two or three layouts in the editor, then compare the stats panel: surface per room and wall length show the real cost of each idea.

Who is this plan for?
