Nine bills, or one.
Run a 15-desk office yourself and rent is just the first of nine line items every month. Flex folds all of them into a single subscription.
+ €1,280/mo for a lean in-house coordinator — the space runs the rest.

This is the market view. We’ll put together your exact lease-vs-flex numbers for 15 desks in Berlin — with real, negotiated flex offers, not estimates.
Access to 1,300+ flex spaces across Europe — WeWork, Mindspace, Design Offices, Regus & more.
Rent less. Use more.
Build your own and every room — meeting, kitchen, breakout — sits inside your lease, paid for and half-empty most of the week. In flex, the big rooms are shared, so your private space shrinks while what you can use multiplies.
Every dashed room is capex + sqm you carry — used a few hours a week.
You rent the purple box. You use everything around it — no sqm, no fit-out.
Assumes ≈13 m²/desk for a self-built office (your own meeting rooms + kitchen) vs ≈7 m²/desk private in flex with shared amenities — about 45% less space to rent. An estimate; adjust to your own plan.
One signature vs. a project plan.
Same 15 desks. The difference is everything that stands between today and your team’s first working Monday.
The lease isn’t always the loser.
Set the amenities aside for a moment. On money alone, a long lease can win — its big upfront cost spreads over the years. The catch: it only works if your team stays put and stays the same size.
Assumes a lease run lean at €380/desk/mo (no shared amenities) plus €16k/desk fit-out, vs. flex at €475/desk all-in. Team change modelled at ±15%/yr.
Same team. A bigger office. €2,480/mo lighter.
For a 15-desk team, flex isn’t just cheaper on paper — it removes the capex, the months, and the long lease entirely.
Office space costs, explained
- How much does office space cost?
- A traditional office isn't a single rent line — it's a stack of nine: rent, fit-out, furniture, IT, utilities, cleaning, insurance, security and management. Counted in full, that's roughly €700–1,200 per desk a month in the bigger German cities. The calculator above shows the real figure for your city and team, next to an all-inclusive flex office that bundles it into one per-desk rate.
- How much office space do you need per person?
- Plan for about 10–15 m² per person in a traditional office once meeting rooms, kitchen and circulation are included — this tool uses roughly 13 m² per desk. In a flex office or coworking space those shared areas are shared, so you rent around 45% less private space for the same team. Change the team size above to see the footprint for your headcount.
- Is a flex office cheaper than a traditional lease?
- Per desk per month a flex office can look more expensive — but a lease also needs capex (fit-out, furniture, deposit) and months of rent before move-in, plus running costs a flex rate already covers. Once the full stack and set-up time are counted, flex is often cheaper overall, especially under ~30 desks or when your headcount is uncertain. The break-even chart shows where the lines cross for you.
- What's included in a traditional office lease — and what isn't?
- The rent is only the start. On top come fit-out and furniture, IT and connectivity, utilities, cleaning, insurance, security and office management — and you carry the whole footprint, including rooms used only part of the week. A flex office or coworking membership rolls all of that into one predictable per-desk price with no upfront capex.
