How to organise a storage unit you can actually walk into

There are two ways to fill a storage unit. One is to pack it like a lorry, front to back, floor to ceiling. The other is to treat it as a very small room you will have to walk around in.

The first fits more. The second is the one you can actually use.

Leave a walkway down the middle

Give up a corridor about two feet wide from the door to the back wall. On a standard ten by ten unit that is roughly fifteen percent of the floor.

In exchange, every box in the unit becomes reachable without unloading anything. If you have ever emptied a unit onto the car park to reach one box at the back, you already know that fifteen percent was cheap.

Put the things you will want along the walkway

Sort by how often you expect to want something, not by size or weight:

• Along the walkway, at eye level: anything seasonal or in active rotation
• Back wall, high: furniture, things going into long-term storage, the boxes you genuinely will not open
• Back wall, low: heavy things you will not move often
• By the door: whatever you brought last and will collect first

Most people do the exact opposite by accident, because the first things carried in go to the back — and the first things carried in are usually the things you were most eager to get out of the house, which are the things you will want back first.

Never stack directly on the concrete

Concrete floors sweat. A cardboard box on a concrete floor will wick moisture out of it for months, and the bottom box in every stack is the one that fails.

Pallets are ideal and often free from the storage facility itself. Failing that, timber battens, a layer of rigid plastic, or even a cheap plastic shelving unit will do. The point is an air gap.

Plastic bins beat cardboard for anything staying more than a season

Cardboard is cheaper, lighter and fine for a move. For anything that is going to sit for a year, plastic bins with lids are worth the money:

• They do not collapse when stacked
• They survive damp
• They keep out insects and mice, which cardboard actively invites
• They stack squarely, which means you can go higher safely

The exception is books and paper, which do better in cardboard because sealed plastic traps moisture against them.

Label the side facing the walkway

This sounds trivial and it is the difference between a useful unit and a frustrating one. Whatever numbering system you use — and a number beats a description every time — make sure it faces the corridor you left yourself.

A stack of twelve identical boxes with their labels facing the wall is a stack of twelve identical boxes.

Take a photograph of the unit before you close it

Stand in the door and take one wide photograph every time you leave. It takes four seconds and it answers the question you will actually have in three months, which is not "what is in bin 14" but "is the thing I am looking for even in this unit".

Keep the index somewhere other than the unit

The failure mode of a well-organised unit is that the organisation only exists in your head. A numbered stack with no lookup is just a tidier version of the same problem.

Keep the record on your phone. Waoo Storage does this specifically for units — each bin gets a printed QR label, and scanning it shows what is inside. It works with no signal too, which matters, because most storage units are concrete boxes with steel doors and no reception whatsoever.

A layout that works for a ten by ten

• Two-foot corridor from door to back wall
• Pallets or battens across the whole floor
• Furniture and long-term boxes against the back wall, stacked high
• Seasonal and active bins along both sides of the corridor, labels facing in
• A small clear patch by the door for whatever you bring next
• One wide photograph from the doorway every time you leave

You will fit perhaps fifteen percent less. You will spend perhaps ninety percent less time in there.
