A storage unit provides space for permitted furniture, audio equipment and other ordinary goods you cannot temporarily keep at home. Check what you plan to store first: artworks, collectibles, irreplaceable items and items of emotional or special value are prohibited.
For an indefinite-term rental: a minimum of one month, then terminable on the monthly anniversary with notice received at least 15 days beforehand. An expressly agreed fixed term remains binding; check your contract.

When is renting storage the right strategic choice?
Sometimes the best place for your things isn't your own home, but a controlled environment where they're safe and protected. When is external storage worth the investment?
Temporary storage for ordinary goods
Consider replaceable furniture, permitted equipment or seasonal items. Make an inventory and check the storage rules before booking. Jewellery, cash, artworks, collectibles and items of emotional or special value are not permitted, even when insured.
Furniture from an inheritance
Not every inherited object belongs in a storage unit. Ordinary replaceable furniture may be suitable, but irreplaceable or emotionally valuable heirlooms are prohibited under article 2.9. Sort your items beforehand and ask Cobalt Box if in doubt.
Seasonal luxuries
Think ski gear, quality camping equipment, outdoor toys, that extra set of garden furniture. These deserve a safe place out of season, so your home stays spacious year-round. Seasonal storage is also a cheap way to keep your home uncluttered every month of the year.
Your home should be a place where you relax, not a depot for things you keep 'just in case'.
Protection: why your home is often NOT the ideal storage spot
Many people try to cram valuables into the garage or attic. Most homes just aren't built for long-term storage of valuable items.

Climate control
In climate-controlled storage the environment is stable. That's crucial for textiles, electronics, photos, paper archives and wooden furniture — all vulnerable to mould or warping in swinging humidity. Attics and garages see daily temperature swings of 15°C or more, disastrous for fine wood or leather.
Security and surveillance
Valuables deserve more than a simple padlock on a shed. With professional camera surveillance, individual access control and our unique Box Alarm, your belongings are safer than anywhere else. Access is easy via a personal code or app, 7 days a week.
Overview and accessibility
In an organised storage unit you find everything at a glance. No hunting through dusty boxes in a half-dark garage — everything neatly stacked and instantly reachable when you actually need it.
Create calm at home, keep the value in your box
By moving what you don't need daily into a secure storage unit, you turn your home from a cluttered space into a calm, liveable environment. It's the smartest way to maximise your living area while protecting your belongings from outside influences.
Do the maths: what does an extra room in your house cost versus a few cubic metres rented month-by-month? Storage rental is often dramatically cheaper than moving to a bigger home.
