Children's rooms are storage problems that change every two years

Treat the sections below as a sequence. With children's rooms, getting the early decisions right makes the later ones much easier.

The requirement turns over faster than furniture does

A cot lasts three years, a toddler bed two, and floor-level play space becomes desk space around the point a child starts having homework. Buying built-in joinery sized to a current stage is the most common way to spend a lot on something that becomes wrong. Freestanding, modular and secondhand pieces suit the timescale better because they can leave without demolition.

The exceptions worth building in are the ones tied to the room rather than the child: a full-height wardrobe, a window seat, a bed platform in a low-ceilinged space.

Storage only works at reachable height

Children tidy into containers they can see into and reach, which means low open boxes rather than high closed cupboards. The upper metre of a wardrobe is adult storage in a child's room and should be planned as such rather than left empty.

Fewer, larger categories work better than many labelled ones, because sorting is the step that gets abandoned. Rotating a portion of toys out of the room entirely reduces both mess and boredom, which is well observed by anyone who has tried it.

Anchoring is not optional

Tall chests of drawers and bookcases tip forward when drawers are opened and climbed on, and this causes serious injuries to small children every year. Wall restraint straps come with most flat-pack furniture and are frequently left in the bag. Fixing into a masonry wall needs the right plug for the substrate, and fixing into plasterboard needs a fixing rated for the load, which the supplied screw often is not.

The quieter point is that if you are unsure what the wall is made of or how to fix into it safely, get someone competent to do it rather than guess.

Floor is the most valuable surface

Young children play on the floor, so clear floor area is the functional equivalent of worktop in a kitchen. Furniture pushed to the perimeter, and a bed that can be against a wall rather than in the middle, both buy playing space. A warm, forgiving floor finish — cork, a thick rug over a hard floor, or carpet — matters more here than in adult rooms.

Underfloor draughts are felt by someone lying on the floor long before they are felt by an adult standing up.

Light for two different activities

Children need bright, well-rendered light for drawing and reading and very low warm light for settling, and one ceiling fitting delivers neither well. A dimmable main light plus a small warm night light covers the range for almost nothing. Blackout blinds matter for early summer mornings at northern latitudes, and blind cords are a strangulation hazard that must be secured out of reach or avoided by using cordless blinds.

A reading light at the bed that the child can operate builds a habit worth more than the fitting cost.

Budgets and buildings differ, and old buildings differ most.

Surfaces that survive

Wipeable paint at child height, an accepted wall for drawing or pinning, and washable rugs remove a recurring source of conflict. Choosing finishes that are repairable rather than perfect means the room can be restored rather than replaced. Involving the child in one or two decisions — a colour, a shelf of their own — reliably increases how much they look after it.

The room will be redecorated more than once, so spending less per round is the rational allocation.

The takeaway

Buy things that can leave, fix the tall ones to the wall, and protect the floor space.

Buy slowly. The gaps are not a problem.
