Long & Narrow rooms

What the condition actually does

Past about 2.5 lengths to 1 width, a room stops working as one space no matter how it is furnished. The answer is zones: two arrangements with their own centres, backs to each other, sharing the room like flatmates. The zone break needs to be physical enough to read — a rug edge, the back of a sofa, an open shelf — but never a wall, which would make two corridors from one.

The first move

Place a rug at each end and nothing in the middle third. The two-room reading appears immediately, and the furniture then has two small easy rooms to solve instead of one impossible long one.

Light under this condition

Light each zone as its own room with its own switch. The unlit middle third at night is not a flaw — the compression between two warm pools is what makes each end feel like somewhere.

What fights it

• One giant rug unifying what should be two territories
• Furniture spread evenly down the length like a waiting room
• A single pendant centred on the room’s midpoint, which belongs to neither zone
