To find larger office spaces for corporate teams in London, start with a clear brief covering headcount, growth plans, budget and preferred locations, then search well beyond the advertised market. Larger requirements, typically 10,000 sq ft and above, are often secured through off-market deals and pre-lets on buildings still under construction. Because these moves usually take 12 to 24 months from first search to moving in, starting early is the single biggest advantage you can give yourself.
How Much Space Do Corporate Teams Need in London?
| Team Size | Typical Space Needed | Realistic Lead Time |
|---|---|---|
| 50 people | 4,000–6,000 sq ft | 9–12 months |
| 100 people | 8,000–12,000 sq ft | 12–18 months |
| 250 people | 20,000–28,000 sq ft | 18–24 months |
| 500 people | 40,000–55,000 sq ft | 24 months or more |
These figures assume roughly 80–110 sq ft per person, which is typical for a Central London corporate office with a healthy share of meeting and breakout space. Hybrid working can bring this down, but only if you are confident about attendance patterns.
Before viewing anything, it is worth working through how to calculate the right office size for your team, including desk ratios and expected growth over the length of the lease.
When Should You Start Searching for a Larger Office in London?
You should start searching for a larger office in London at least 18 to 24 months before you need to move. Large, high-quality floorplates are in short supply across Central London, and the best buildings are often let long before they complete.
Timing is also tied to your current lease. Check your expiry date and any break clause carefully, as notice periods of six to twelve months are common. Missing a break date can leave you paying for two offices at once, or locked into a space your team has outgrown.
A realistic timeline for a 20,000 sq ft move looks something like this:
- Months 1–3: Agree the brief, budget and workplace strategy.
- Months 3–6: Shortlist buildings, view and compare options.
- Months 6–9: Negotiate heads of terms and instruct solicitors.
- Months 9–12: Complete the lease and design the fit-out.
- Months 12–18: Build out the space and plan the move.
Where Are the Best Large Floorplates in London?
The best large floorplates in London are concentrated in areas with modern or comprehensively refurbished stock, including King’s Cross, Paddington, Victoria, Fitzrovia and the City. Each offers something different.
- Victoria and Westminster: Large, efficient buildings close to government and with excellent rail links. Pilcher London is currently marketing Greencoat & Gordon in Victoria, offering from 20,000 up to around 107,000 sq ft.
- Fitzrovia: A West End address with more realistic rents than Mayfair. Middlesex House on the edge of Fitzrovia offers 20,000–46,935 sq ft.
- King’s Cross: Modern campus-style buildings popular with tech, life sciences and media occupiers.
- Paddington: Strong value and direct Elizabeth line and Heathrow Express connections.
- The City: The deepest supply of large, highly specified floorplates in London.
You can browse current availability in our large office spaces to rent in London listings, although many of the most suitable options never appear online.
What Should Corporate Occupiers Look for in a London Building?
Corporate occupiers in London should look for efficient floorplates, strong building services and good environmental credentials. The BCO Guide to Specification is a useful benchmark for what a modern, well-specified office should provide.
Key points to check include:
- Floorplate efficiency: Regular, column-light floors are easier to plan and waste less space.
- Lift capacity: Large teams arriving at 9am can overwhelm undersized lifts.
- EPC and ESG ratings: Many corporates now have net-zero commitments, and minimum energy standards for commercial buildings continue to tighten.
- End-of-trip facilities: Showers, lockers and cycle storage are now expected rather than a bonus.
- Contiguous space: Keeping a team on connected floors makes a big difference to culture and collaboration.
Why Use a Tenant Representation Agent For Corporate Offices in London?
A tenant representation agent may be good to use when looking for a corporate office in London, because a tenant representation agent acts solely for you, rather than for the landlord, and gives you access to buildings that are not openly marketed. For larger requirements, this can be the difference between a good deal and a great one.
A tenant representation agent will typically:
- Search the full market, including off-market and pre-let opportunities.
- Run a competitive process so landlords bid for your business.
- Negotiate rent, rent-free periods, capital contributions and break clauses.
- Coordinate solicitors, surveyors and fit-out teams.
On a large corporate letting, landlord incentives can be substantial. A strong negotiator can secure meaningful rent-free periods or a contribution towards fit-out, which often outweighs the cost of advice many times over.
Should You Consider a Pre-Let For Corporate Offices in London?
A pre-let can be an excellent option for large corporate teams in London that plan well ahead. By committing to a building before it completes, you can often influence the specification, secure the best floors and negotiate more favourable terms.
The trade-off is risk. Construction programmes can slip, so your lease on your current office needs enough flexibility to cope with a delay. Your agent and solicitor should build protections into the agreement for lease.
How Can Pilcher London Help Your Corporate Team Find a Larger Office?
Pilcher London helps corporate teams find larger offices by acting as their dedicated adviser from the first brief to the day they move in. We are a niche London commercial agency specialising in offices of every size across Central London and beyond.
What sets us apart for larger requirements:
- London-wide knowledge: We know the buildings, the landlords and the developments in the pipeline, including space that has not yet reached the open market.
- An architectural eye: Our partners include an honorary fellow of the RIBA and a partner trained in architecture, so we assess how a floorplate will actually work for your team, not just its headline size.
- Commercially sharp negotiation: We have agreed some of London’s record-breaking office rents and know how to secure the rent-free periods, capital contributions and break clauses that matter on a large deal.
- A joined-up process: We bring tenants, landlords, architects and designers together, so the search, the lease and the fit-out all point in the same direction.
Our clients range from fast-growing businesses to established international firms. When The Blair Partnership needed room to grow, our team searched the entire market, vetted every option and secured 15 Fitzroy Street, a modern building that fitted their plans perfectly.
We are also currently marketing large-scale opportunities such as Greencoat & Gordon in Victoria and Middlesex House in Fitzrovia, alongside a wider pipeline of off-market space. Call us on 020 7399 8600 or request a callback to talk through your requirement.
Final Thoughts
Finding a larger office for a corporate team is a strategic project rather than a property search. Defining your brief early, understanding your lease position and seeing the whole market will give you far more choice and stronger negotiating power.
