Designing a kid's room they won't outgrow in two years

A room built around a cartoon has a shelf life of about eighteen months. A room built around how a child actually uses space lasts until they leave for college. The trick is knowing which parts to fix and which to leave loose.

Fix the expensive things. Keep the cheap things changeable.

Joinery, flooring and lighting are expensive and disruptive to redo, so keep them plain, well made and neutral. Bedding, wall art, paint on one wall, desk accessories and knobs are cheap, so let those carry the personality — and let them change every couple of years without a carpenter.

Put the theme on the things you can replace in an afternoon.

Design for the child they're becoming

• A desk from the start, even at five. It becomes homework, then a laptop, then everything. A 24-inch-deep worktop the length of one wall outlasts three separate desks.
• An adjustable hanging rail in the wardrobe, low now, raised later — one drill, ten years.
• Storage at their height. A child tidies what they can reach. Open bins at floor level, closed cupboards above for the things you'd rather they didn't.
• A full-size bed early, if the room takes it. Toddler beds are outgrown almost immediately.

Bunks and lofts

Built-in beats bought. A bunk made as joinery lets the ladder, the guard rail and the step depth be done properly, and the space underneath becomes storage or a desk rather than a place things get kicked. It also gets fixed to the wall, which matters at 2am.

Check the ceiling height before you commit: you want a clear sitting-up height on the top bunk, or nobody will use it twice.

The unglamorous specifics

1. Round every corner on joinery below adult waist height.
2. Wipeable paint — a washable emulsion, not a flat finish, on every wall to about four feet.
3. Sockets high and switched, and more of them than you think: chargers, a lamp, a fan, later a monitor.
4. Two lighting circuits — a bright one for the desk, a soft one for bedtime. Same argument as anywhere else in the house, more useful here.
5. Blackout curtains. Sleep is the actual brief.

Done this way the room quietly grows up on its own, and the only thing that dates is a poster.
