An office move almost never fails on moving day. It fails because the old lease ends on a fixed date and the new space is not ready on that date. The short answer on how to move offices without business interruption: do not plan backwards from moving day, plan backwards from the end of the fit-out — and have a solution ready for the gap in between before you need it.
The critical path is the fit-out, not the logistics. Crates, movers and cabling can be handled over a weekend. A fit-out cannot.
Why moving day is not the problem
For a mid-sized office of 500 to 1,500 square metres, a typical tenant fit-out takes around 12 to 20 weeks according to project managers. Roughly four to eight weeks go to planning and tendering, six to twelve weeks to construction, and one to two weeks to handover.
Two details matter most. First, more than 70 percent of the eventual cost is locked in during detailed planning and tendering — long before the first contractor sets foot on the floor. Rushing that phase to save time saves it in the wrong place.
Second, those 12 to 20 weeks assume nothing goes wrong. Permits, lead times for partition walls or ventilation equipment, and variation orders routinely push the date by weeks. And because the old lease ends on a fixed date, every delay hits operations directly — or the budget, in the form of double rent.
How much lead time is realistic
The lead times used in the relocation industry run considerably longer than most teams first assume:
| Team size | Recommended lead time | What sets the pace |
|---|---|---|
| Up to 20 people | 4 to 6 months | Search and contract negotiation |
| 20 to 50 people | At least 6 months | Fit-out becomes the critical path |
| 50 to 200 people | 9 to 12 months | Permits, tendering, IT concept |
| Over 200 people | 12 months and up | Phased move, change communication |
The most common planning error is not undershooting these windows — it is counting them from the wrong point. Many teams count from contract signature. The right start is the day the search begins. Between a first viewing and a signature-ready contract, four to eight weeks often pass in the flex office market, and considerably more for conventional commercial space.
The gap between the old lease and the new one
This is where a move either hits the business or does not. Three constellations are possible, and they differ substantially in cost:
| Scenario | What it costs | When it makes sense |
|---|---|---|
| Overlap Old space runs on | Double rent for the overlap period | When the extension is short and the premium is calculable |
| Interim space Temporary solution | Rent for a few months, no investment | When the gap is three months or more |
| Phased move Teams relocate in sequence | Higher coordination effort | When the new space completes in sections |
The interim option is regularly considered too late. Yet it is the only one of the three that still works when the fit-out slips unexpectedly — and it is usually cheaper than extending the old space, where service charges and maintenance keep running alongside the rent. How to cut such a period cleanly in contract terms is covered in our article on temporary office space.
“In over nine years in the market I have barely seen a move go wrong on moving day. The ones that went wrong were those where the fit-out finished six weeks later than planned and nobody had a plan B. Six weeks without a working office costs more than any interim rent.”

Why most moves today are downsizes
An office move used to mean taking more space. That has reversed. In the study Adaptive Spaces — 2026 Global Workplace & Occupancy Insights, 57 percent of corporate real estate teams expect a footprint reduction within the next three years. The main reason, cited by 67 percent, is lower space demand from hybrid working models.
How much room there is shows in the Desk Sharing Index 2026: average desk utilization in German offices sits at 31 percent. Moving one-to-one carries that under-utilization to the new location — and pays for it there for the next five to ten years.
In practice: a move is the one moment when floor area can be corrected without breaking a contract. That opportunity passes unused when space requirements are derived from the old floor plan rather than from actual attendance. How to work that through is in our article on calculating the office space you need.
What actually goes down on moving day
The space is rarely the bottleneck. Downtime arises in three other places, and all three can be defused in advance.
IT. The business internet connection at the new site has lead times that have nothing to do with your moving date. Depending on provider and building, several weeks can pass between order and activation. Order it only after signing and you often have an office without a line. A mobile stopgap carries a small team, but not video calls for thirty people.
Reachability. Number porting, call forwarding and mail redirection do not always take effect to the day. That gets critical wherever customers call or deadlines depend on incoming post. A business address with a professional mail service bridges this phase more reliably than a private forwarding order — see our article on the business address in a business centre.
People. A move costs productivity even when everything works technically. New routes, new seating, missing cables. One to two days of reduced output is realistic even with good planning. Teams that plan for it rather than argue it away put the move on a weekend with a quiet following week — not before quarter end.
How to bridge the transition
When a gap sits between move-out and move-in, flexible space is the obvious bridge. Furniture, internet, reception and meeting rooms are already there, the term can be cut to a few months, and no investment arises that would have to be written off after move-in. How the model works is explained in our article on renting a flex office in Germany.
Three points to settle before signing. First, the extension option: if the fit-out slips, you need the ability to extend month by month — otherwise you trade one deadline problem for a second. Second, the commute: interim space that is hard for the team to reach produces exactly the downtime you were trying to avoid. Third, the notice period, so the stopgap does not run longer than needed. Which clauses count is covered in our checklist on reviewing a coworking office contract.
CoWorking Capital compares available space across Germany, filters by realistic availability on your target date, and negotiates term and conditions up to signing readiness — commission-free on the tenant side. With a fixed move-out date in particular, what counts is that the options proposed are genuinely free on the day. Location overviews are available for Berlin, Munich, Frankfurt and Hamburg.
An office move without business interruption is ultimately not a question of which removal firm you hire. It depends on whether the fit-out date was set realistically and the gap in between solved beforehand. Both are decided months before moving day.
