Planning a 3×6 Meter Room
3×6 m is the single garage of European housing (the minimum most planning authorities accept), the lounge of a narrow terraced house, and the standard footprint of a garden room or log-cabin office. Eighteen square metres in a 3-m width is a long room that wants zoning.
A 1:2 ratio, 600 cm long. As a garage it fits a 460-cm family car with 140 cm to spare, but at 300 cm wide a 185-cm car leaves 57 cm per side, which opens one door partly. As a living space it is two 3×3 m rooms end to end.
What this size is best used for
- 1Single garage
A 460×185-cm car centred leaves 57 cm each side (a door opens about 40°) and 600 − 460 = 140 cm at the end for a 60-cm bench and 80 cm to stand.
- 2Garden office with a sofa bed
A 160-cm desk across the far 3-m wall (70 cm each side) and a 200-cm sofa bed on a long wall near the door, 600 − 80 − 200 = 320 cm apart when closed and 320 − 120 = 200 cm when opened.
- 3Long lounge
Sofa (220×90 cm) on a long wall in the far half, a 100×50-cm coffee table, a TV unit opposite (path 300 − 90 − 40 − 50 − 40 = 80 cm), and a 160-cm bookcase plus armchair in the near half.

Furniture sizes are the same true-to-scale pieces in the RoomSketch3D catalog; clearances are what is left after each step.
- Door: a 240-cm sectional door in the front 300-cm wall leaves 30 cm each side; a 250-cm door is the maximum with a 25-cm jamb.
- Car (460×185 cm) parks centred, 57 cm from each side wall, nose 140 cm from the back wall.
- Bench 180×60 cm across the back wall's left portion at 90 cm high, leaving 300 − 180 = 120 cm of the back wall for a 60-cm tall cupboard and a 60-cm bin; 80 cm of standing room in front of the bench.
- Nothing on the side walls below 150 cm along the car's length; 30-cm shelves above that height on one side, and the side door, if any, in the rear 140-cm zone.
Mistakes this size invites
- A 190-cm-wide SUV: 55 cm per side and a door that opens 30 cm, so the driver gets out at the rear zone by pulling forward only if the car is under 460 cm long.
- Shelving along a side wall at hip height: 30 cm of shelf leaves 27 cm beside the car, and no door opens at all on that side.

Maximum Furniture Sizes for a 3×6 m Room
Lists like this can't tell you if it actually works
"A 3-seater sofa fits" is true — until the door swing eats half a meter of wall, the radiator blocks the long wall, or the walkway to the window shrinks to 50 cm. The only way to know your layout works is to see it: draw the 3×6 m room, place real furniture at true scale, and check the flow.
That's exactly what RoomSketch3D does. Drag-and-drop true-to-scale furniture pieces into your exact room and walk through it in 3D — before you buy, move, or assemble anything.
