People use "coliving" and "colocation" like they mean the same thing. A shared kitchen, a few bedrooms, strangers becoming roommates. From the outside, sure.
The difference that actually matters is on page one of the contract, and almost nobody checks it before signing.
The one clause that changes everything
In a classic Brussels colocation, everyone on the lease is jointly and severally liable for the whole rent. Not just their share. The whole thing.
That word, "solidaire", shows up in nearly every Belgian colocation contract. It means if your flatmate stops paying, or leaves without notice, the landlord can legally come after you for the full amount. Not their third. The full rent, until a new tenant is found and added to the lease. Droits Quotidiens, a Belgian legal-info service, confirms this clause isn’t legally required, but it’s included in nearly every colocation contract because it protects the landlord, not the tenants.
Most people who’ve done a colocation in Brussels have a story about this. A roommate who left with two months’ rent unpaid. A ghosted deposit split. An avenant (lease amendment) that took six weeks to sort out with three signatures and a landlord who wasn’t in a hurry.
None of that makes colocation a bad option. It makes it an option with a specific kind of risk that most people don’t think about until it happens to them.
Coliving vs colocation, side by side
| Colocation | Coliving | |
|---|---|---|
| Contract | One shared lease, all names on it | Individual contract per resident |
| If a flatmate stops paying | You can be liable for their share | Not your problem |
| Bills | Split informally or via a house kitty | One invoice, all-inclusive |
| Minimum stay | Tied to the shared lease | From 1 month |
| Who manages repairs | You, calling the landlord | A management team |
How colocation actually works in Brussels
You’ll usually find these on Facebook groups (Erasmus Housing Brussels, Colocation Bruxelles, that kind of thing) or on listing sites where a current tenant is looking for a replacement roommate.
What you’re signing up for:
- One shared lease, usually a standard Belgian rental contract, with everyone’s name on it
- A deposit split between roommates, sometimes via Belgium’s official e-deposit system, sometimes just handed to whoever manages the flat
- Utilities and internet billed separately, or informally split by whoever’s turn it is to deal with it
- No professional management. If the boiler breaks, you’re calling the landlord yourself, and waiting
The upside is real: it’s usually the cheapest way to get a private room in a good neighbourhood, and you get to pick, or inherit, your own flatmates.
The part that catches people off guard is the admin. Setting up a Belgian bank account, registering at the commune, sorting the internet contract in your name or someone else’s, working out who owes what for the electricity bill from March. If you’re arriving for a 5-month traineeship with two weeks’ notice, that’s a lot to take on for a room you’ll live in for one semester.
How coliving is built differently
Coliving takes the same physical setup, private room, shared kitchen and living room, and puts a single operator behind the contract instead of a group of individual tenants.
At TwentySeven, that means one contract in your name only, so your flatmate’s rent has nothing to do with yours. One monthly invoice covering rent, WiFi, utilities and weekly cleaning of shared spaces. Contracts starting from 1 month, not a multi-year Belgian lease. A management team you can actually reach when something breaks, instead of a landlord you’ve never met.
You’re still sharing a kitchen with other people. You still don’t get full apartment-level privacy. What disappears is the shared financial exposure and the DIY admin.
Rooms in our co-living properties in Ixelles, Etterbeek and Saint-Gilles start at €595/month, all-inclusive.
So which one should you pick
If you’re staying under six months, arriving from abroad, or you don’t want your housing situation to depend on a roommate you’ve never met, coliving removes the risk that colocation carries by design.
If you’re staying long-term, already have a group of friends lined up, and you want the lowest possible monthly cost, a colocation can work. Just read the "solidaire" clause before you sign, and know exactly who you’re sharing a lease with.

FAQ
Is coliving more expensive than a colocation?
Usually, yes, per month. But a colocation deposit, agency fees, and the risk of covering a flatmate’s unpaid rent aren’t part of the sticker price. Factor those in before comparing on rent alone.
Can I leave a coliving contract early?
TwentySeven co-living contracts start from 1 month, so you’re not locked into a multi-year Belgian lease. Terms depend on your specific contract; check with our team before signing.
Do I need a Belgian guarantor for co-living?
Not always. It depends on your contract length and nationality. Our team checks this with you individually.
What happens if my roommate in a colocation stops paying?
Under a standard joint-liability ("solidaire") clause, the landlord can pursue any tenant on the lease for the full rent, not just their share. This is the main structural difference from coliving, where each resident has their own contract.
