How to organise a basement storage cage and know what's down there

Start with what is there

A cage is cheap space, and cheap space fills up. Before you buy a single shelf, take everything out into the corridor, or at least everything from one side, and sort it into four piles: keep in the cage, belongs upstairs, give away or sell, throw away.

Be honest about the last two. A box that moved with you twice and was never opened is telling you something. If you could not say what is in it, and nothing in it is a document or a keepsake, open it before you decide. If it turns out to be nothing you would miss, it can go.

While it is all in the corridor, wipe the floor and check the walls and the corners for damp. It is the one moment you can see the whole floor.

Use the height, not the floor

Most cages are small on the floor and tall in the air. Floor-to-ceiling shelving is what turns a cage into a room you can use, but plan it with care:

• Shelves deep enough for your boxes and strong enough for the heaviest one. Boxes should not stick out into the walkway.
• Heavy things low. Tins of paint, tools, tiles, books. Light and bulky things go up high: bedding, seasonal decorations, empty bags.
• Leave a walkway you can walk along without turning sideways, and keep the back reachable. A shelf you can only reach by moving three boxes is a shelf you stop using.
• Everything off the floor. Even a few centimetres is enough to save a box from a small leak.

Open metal shelving is usually better than a closed cupboard here. Air gets through it, and you can see where things are.

Boxes: the same size, one kind of thing

Use boxes of one or two sizes. They stack, they fit the shelves without gaps, and they can swap places without a puzzle. Choose lidded plastic for anything you want to keep, as cardboard is fine for a short stay and poor for years in a cellar.

Pack by kind, not by room or by date: "Camping", "Christmas", "Kids' clothes 2–3 years", "Spare bathroom fittings". A box labelled "misc" is the one you will end up emptying onto the floor. Do not fill a box to the top. Leave a hand's width, so you can add one more thing without starting a new box.

Things that don't fit a box, such as a ladder, a folded pushchair or a rolled rug, get their own spot along the wall, on hooks or standing in a corner.

Label so you can read it from the walkway

Write the label on the short end of the box, the side that faces you on the shelf, and make it large enough to read from a step away. Use the same pattern on every box: a short code, then the contents in a few words, for instance "S12: ski gear, goggles, helmets".

Put a sign on the shelf as well, such as "Left, shelf 2", so a box has an address and not only a name. Then "S12 is on the left, shelf 2" is something anyone in the household can follow.

Keep a record of what is down there

Labels tell you which box is which. A record tells you which box holds the thing you are looking for. It does not need to be detailed: for each box, its code, its shelf and the main things inside are enough. Write it as you pack each box, not afterwards from memory. A list in a notebook or a spreadsheet works. A photo of each open box, taken before you close the lid, works too, and takes moments.

Basements often have no mobile signal, so the record has to work with no connection. A printed copy taped inside the cage door, or an app that works offline, covers it.

Name the cage so it cannot be confused with other places: "Building A, cellar cage 14". If you also have a garage or another storeroom, give each its own name.

Keep it working

A cage stays in order when putting things back is as easy as dropping them. Leave one shelf, or half a shelf, empty for things that arrive. Keep one "to sort" box by the door and empty it every few weeks.

When you take something out for a season, note it. Most things that are "lost" in a storeroom have only been carried upstairs and never came back. Once a year, spend an hour walking through, put wrong boxes in the right place and decide about whatever stayed closed all year. The declutter by a rule guide helps with that last part.

Doing it with Neatkept

In Neatkept the cage is a place in Places, with its shelves and boxes inside, and a thing can sit in a box or right on a shelf. Photograph an open box or a shelf and AI proposes what it sees; you keep or drop each thing with a tap, and nothing reaches AI until you allow it. Boxes and shelves can carry printed QR labels that open them from a scan with everything inside; a box can also carry a code written with a marker, which you type under the scanner. With no signal in the cellar, search, scanning labels, adding and moving still work, and changes sync once you are online (photos wait until then). Later, "where are the kids' skis?" answers with the place, the box and a photo. The storeroom with no signal page shows how.
