The Multi-Purpose Storage Unit Style Map of Britain

Multi purpose storage sells because British homes have lost their cupboards. Older housing hid its clutter in an under stairs cupboard, a larder and a boxroom. Newer housing and converted flats often have none of these, and the storage that used to be built into the fabric of the house now has to be bought as furniture and stood against a wall.

No national dataset records how much built in storage British dwellings contain, so a genuine style map cannot be drawn from measurement. What can be mapped is the relationship between property type and storage deficit, and that relationship is consistent enough to plan from. It also explains why the same unit is bought for entirely different reasons in a Victorian terrace and a new build flat.

Key findings at a glance

• Storage units are most often bought to replace a function the building does not provide, rather than to add capacity to a room that already has cupboards.
• The Nationally Described Space Standard sets internal floor area and built in storage requirements for new dwellings, which is the published context for how tightly storage is planned in newer homes.
• Unit depth of 35cm to 40cm holds most household items including box files, folded textiles and standard storage baskets, while 30cm suits books and display only.
• Anything above about 150cm tall should be secured to the wall, and in rented homes that requirement conflicts with restrictions on fixings.
• Open cube storage costs nothing in perceived space but shows everything, so it works only where the contents are contained in matching boxes or baskets.
• Combination units with a closed base and open top perform best in rooms visible from a doorway, because clutter sits below eye line.

Older housing: the storage exists but it is in the wrong place

Victorian and Edwardian terraces typically have an under stairs cupboard, deep alcoves either side of a chimney breast and sometimes a small third bedroom used for storage. The problem in these homes is not total volume but distribution. The alcoves are awkwardly proportioned for standard furniture, and the under stairs space is a triangular void that swallows items and never gives them back.

Our advice in this kind of property is usually to work with the alcove rather than against it. A unit sized to the alcove width, even if it means a narrower piece than the household wanted, keeps the chimney breast reading as a feature and avoids the gap that collects dust either side of a standard width unit. Where the alcove is deep, shelving from shelving units and storage UK often makes better use of it than a cabinet with a fixed carcass depth.

New build and flats: the deficit is structural

In newer housing, room sizes are planned closely and the storage provided is generally the minimum the design requires. Converted flats are frequently worse, because a conversion divides a house that had one set of cupboards among several dwellings. The result is that furniture has to provide the entire storage function for coats, shoes, cleaning equipment, bedding and everything seasonal.

This is where the multi purpose unit earns its name. A single piece that offers closed cupboards for the things nobody wants to see, drawers for small items and open shelving for display is doing the work of three separate pieces in a room that only has wall for one. Households in this position often compare a general purpose piece from modern storage furniture UK against a sideboard, and the sideboard frequently wins on the ground that a flat top at around 75cm to 80cm is usable surface as well as storage.

Height, depth and the physics of a tall unit

Two specifications determine whether a storage unit works: depth and stability. Depth is the more commonly misjudged. A 30cm carcass holds books and ornaments but will not take a standard storage basket or a box file laid flat. At 35cm to 40cm, most household items fit, which is why that band dominates general purpose units. Going deeper than 45cm rarely helps, because items at the back become invisible and therefore forgotten.

Stability is a safety matter rather than a preference. A tall unit with weight loaded high has a genuine tipping risk, particularly where children climb. Any unit above roughly 150cm should be fixed to the wall with the supplied bracket, and load should be distributed with heavy items low. In a rented home where fixings are restricted, the honest answer is to choose a lower, wider unit rather than a tall one left unsecured. Two units of 90cm high side by side give similar volume to one of 180cm with none of the risk.

Matching a unit to the room and the property

The table below sets out what different unit configurations hold and where they suit, based on standard furniture dimensions and the storage needs of specific room types.

Use it to identify the configuration before shopping for a finish, since configuration is much harder to change later.

What this means for UK homes

Audit before you buy. Write down what actually needs a home and measure the largest awkward item, whether that is a vacuum cleaner, a folding chair or a set of ring binders. Buying a unit and then discovering the vacuum does not fit is the most common storage disappointment, and it is entirely avoidable with one measurement.

Decide what must be hidden. Open shelving is cheaper in perceived space but only works if contents are uniform. If the household reality is mixed packaging, paperwork and children’s things, choose closed doors for the bulk and keep open shelving for a small deliberate display. A closed base with an open top is the compromise that survives real life in most rooms.

Use vertical space where floor is scarce, but secure it. In a small flat the wall above waist height is usually the only unused space left, so a taller unit is often the right call. Fix it to the wall, put the heavy things at the bottom, and where fixings are not permitted go wider and lower instead. In bedrooms, the same audit frequently points towards a proper modern wardrobes UK solution rather than more shelving, and in living rooms a piece from modern sideboard furniture UK gives storage plus a working surface for lamps and daily items.

Methodology

This 2026 report is an editorial assessment by the Furniture in Fashion team as a UK modern furniture retailer, drawing on the storage problems customers describe to us and the guidance we give in practice. All measurements are standard furniture dimensions, given in centimetres with imperial equivalents where useful. Housing context is drawn from named published UK sources where genuinely applicable, principally the Nationally Described Space Standard for internal floor area and built in storage requirements in new dwellings, and the English Housing Survey for the age profile of the stock. No national dataset records the amount of built in storage in British dwellings, so the patterns described by property type are structural inferences rather than measured findings, and this report contains no proprietary sales data, search data, customer data or survey fieldwork. Our full range is available at Furniture in Fashion.

Please describe it as our editorial assessment of how British property types create storage deficits, supported by standard furniture dimensions, rather than as a measured survey.

Frequently asked questions

How deep should a storage unit be?

Between 35cm and 40cm for general household use, which takes standard storage baskets and box files laid flat. A 30cm carcass suits books and display only. Beyond 45cm items at the back become invisible and stop being used.

Do I need to fix a storage unit to the wall?

Any unit above roughly 150cm tall should be fixed with the supplied bracket, and load should be kept low in the carcass. Where fixings are not permitted, choose two lower wide units rather than one tall unit left unsecured.

Is open or closed storage better?

Closed for bulk, open for a small deliberate display. Open cube storage only looks calm when contents are uniform, so it needs matching boxes or baskets to work. A closed base with an open top is the configuration that copes best with real household clutter.

Why do new build homes need more storage furniture than older houses?

Because their storage is planned to the minimum the design requires, and they rarely have the under stairs cupboard, larder or boxroom that older housing used. Converted flats are often tighter still, since a conversion splits one house’s cupboards between several dwellings.
