Free Granny Flat Floor Plan

About this plan

A granny flat floor plan is step-free, bright and self-contained, ideal as a backyard home for a parent or a tenant. This free plan fits a 7 × 5 metre footprint (about 23 × 16 feet) and gives 35 m² (377 sq ft) of enclosed floor space once the walls are in place. It includes no separate bedroom and 1 bathroom. Open it in the editor to move walls, swap furniture or walk through it in 3D.

Room-by-room layout

The layout is split into 2 rooms. The main room is 28.8 m² and combines sleeping, living and cooking; bathroom covers 6.3 m² with a toilet, a basin and a shower. The largest space is the studio at 28.8 m², and the smallest is the bathroom at 6.3 m². Altogether the plan counts 2 doors, 4 windows and 29.0 m (95 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?

This size suits a single person, a guest unit or a weekend retreat, and it is quick and affordable to build. Use the free editor to adapt the plan to your plot: drag the wall handles, add doors and windows, and drop in any of the 100 furniture models.
