Short answer: yes, a desk belongs in a living room as long as you hold three numbers. Keep a 90 cm walkway behind the chair, use a desk no deeper than 60 cm, and leave 45 cm between the chair back and the nearest sofa. Hit those and the corner reads as a deliberate study nook; miss them and you have rebuilt the office cubicle you were working from home to escape.

The reason most living-room desks look wrong is not the desk. It is the chair. A desk pushed into a corner takes up 120 × 60 cm, but the moment a human sits down the footprint triples: 75 cm of pull-out, elbows out, a coffee cup migrating towards the keyboard. Plan the chair's territory first and the desk becomes easy.
The walkway test: 90 cm
Ninety centimetres is the width at which two adults pass each other without either turning sideways, and it is the same figure building codes use for a habitable corridor. Below 90 cm, every trip to the kitchen becomes a negotiation with a chair.
| Room width | Desk you can fit | Walkway left | Verdict |
|---|---|---|---|
| Under 300 cm | Wall-mounted 100 × 45 cm, no chair | 90 cm+ | Standing or stool-only desk |
| 300–340 cm | 100 × 50 cm against the short wall | 90–110 cm | Works, chair tucks fully under |
| 340–400 cm | 120 × 60 cm | 110 cm+ | Comfortable for daily use |
| 400 cm+ | 140 × 70 cm or a return | 120 cm+ | Full-time work without a study |
Note that a 45 cm deep desk is fine for a laptop and miserable for a monitor. Depth is not a style choice, it is a sightline: 60 cm is the shallowest top that lets a 27-inch screen sit 60–75 cm from your eyes without your nose touching the bezel.
Placement: three spots that work
Behind the sofa. The classic. A 120 cm desk behind a 200 cm sofa uses floor that was already dead space, and the sofa back does the zoning for free. You need 110 cm between the sofa back and the wall — 45 cm of desk plus 65 cm of chair — which most rooms have if the sofa is not jammed against the skirting.
The window wall, turned sideways. Perpendicular to the glass rather than facing it. You get daylight without screen glare, and the radiator stays clear. Sitting square-on to a window in winter means staring into a black mirror from 4 pm onwards.
The alcove. A chimney breast recess of 100–130 cm is a ready-made office. Add a shelf above the desk at 145 cm and the desk stops needing drawers, which buys back 10 cm of legroom.
The 45 cm sofa rule
Forty-five centimetres is the gap at which a dining-style chair can be pushed back and stood up from without banging the sofa. Sixty centimetres is nicer. But there is a second constraint people forget: sightlines. If your chair faces a wall 45 cm behind a sofa, you are working while staring at the back of a sofa at eye level, which is exactly as motivating as it sounds. Face the desk along a wall instead, so the sofa sits in peripheral vision rather than dead ahead.
Zone it without building walls
Three cheap cues do more than a room divider. A rug sized 200 × 140 cm under the desk and chair marks the work zone and absorbs the chair-roll noise that makes downstairs neighbours creative with a broom. A single tall lamp behind the desk at 160 cm gives a pool of light rather than competing with the ceiling fixture. And books or a low 90 cm shelf against the desk's back edge create a visual 10 cm wall that costs nothing and blocks the cable spaghetti.
What to avoid: a desk angled diagonally in a corner. It looks dynamic in photographs and steals 30 cm of usable floor from both walls, and no chair ever sits straight at it.
Cable management, because this is a living room
Budget 10 cm behind the desk for a cable tray plus 5 cm of clearance from the wall, so a 60 cm desk needs 65 cm of floor. Run one extension lead along the skirting to the nearest socket rather than three cables across the rug. If the desk has a back panel, drill nothing — route cables through the 8 cm gap under the top; if it does not, a £12 clamp-on tray under the rear edge hides 95% of the mess in ten minutes.
When it does not work
If the only free wall is the one the TV faces, do not put the desk there. Two screens in one sightline means you will watch neither properly. And if your flat has a 280 cm-wide living room with a 220 cm sofa already in it, the honest answer is a folding wall desk 80 × 50 cm and a stool you store behind the sofa — a permanent desk in that room would eat the only walkway you have.
