Small-space storage advice usually amounts to “buy fewer things”, which is true and unhelpful. The more practical observation is that most apartments have a surprising amount of unused volume, and almost none of it is a standard size.

The dead zones

Walk around and look for these: the gap beside the fridge, the space above a door frame, the dead corner of a kitchen cupboard where the shelf is deeper than your reach, the 15cm beside a washing machine, the vertical space above a hanging rail. Every one of them holds something and none of them fits a shop-bought box.

Go up before you go out

Floor space is what you are short of; wall and vertical space usually is not. Wall-mounted shelves, hooks and organisers convert unused wall into storage, and printed ones are light enough for adhesive fixings if you rent. Our wall shelf guide covers the fixings.

Shelf risers double a cupboard

A cupboard shelf with 30cm of height and 12cm of plates is wasting more than half its volume. A riser creates a second level instantly. This is the highest-return change on this list and it costs almost nothing.

Divide every drawer

An undivided drawer becomes a bin within a week regardless of how carefully you arrange it. Dividers work because everything gets an assigned slot, and assigned slots are the only reason things get put back. Printed dividers can be sized to the exact internal dimension of your drawer rather than the nearest available – which matters, because drawers are never a standard size.

Stack, do not spread

Modular boxes that interlock let you build up to fill a height. Stackable boxes beat one large container because you can reach the bottom one without unpacking the top.

Measure three times

Before ordering anything, measure the width at the front and the back, and the height at both ends. Older buildings are not square. A box that fits at the front and jams at the back is the most common storage disappointment there is.

When to go made-to-measure

For a gap you look at every day, a box sized exactly to it costs a little more in design time and nothing in setup, because there is no mould. Send us the measurements and a photo, and we will tell you honestly whether a stock size would do the job first.
