A built-in cupboard is only as good as the measurements behind it. The same run of doors can be the most useful thing in a house or a wall of wasted depth, and the difference is decided room by room.
Bedrooms
The bedroom cupboard does the heavy work, and it needs depth to do it. 600mm is the right depth for hanging. A coat hanger is about 450mm wide and needs room to hang without catching the doors. Below 550mm, hangers sit at an angle and the doors rub.
Take it to the ceiling. A cupboard that stops short leaves a dust shelf on top and wastes the space where the suitcases and spare duvets should go. A full-height run, scribed to the ceiling, reads as part of the wall rather than furniture pushed against it.
Mix the interior: long hanging for coats and dresses, double hanging for shirts, and drawers behind the doors for everything folded. We cover the detail in planning a walk-in wardrobe.
Passages and linen cupboards
A passage rarely has 600mm to spare, and a linen cupboard does not need it. Folded sheets and towels sit comfortably on shelves 400–450mm deep, which keeps the passage clear. Make the shelves adjustable, because bedding and towels stack to very different heights.
Entrance halls
The cupboard by the front door takes coats, shoes, bags and everything that arrives with them. Shoes need only about 350mm of depth, so a shallow shoe section beside a deeper coat section often fits where a single deep cupboard would not. A vented door or back keeps it fresh.
Under the stairs
The space under a staircase is usually a dark cupboard with a door. Pull-out drawers on runners, cut to the slope of the stairs, turn it into storage you can actually reach: cleaning equipment, the vacuum, or the things that currently live in the garage.
Children's rooms
Children outgrow a cupboard long before the cupboard wears out. Rails and shelves that move let the same run of doors work for a toddler's clothes now and a teenager's later, without rebuilding anything.
One hand, the whole house
Built-in cupboards look best when they share the same doors, handles and shadow lines from room to room. Drawn together, they read as part of the house rather than a collection of cupboards. See how we approach wardrobes and fitted runs.
