How to plan office space: layout, flexibility and future-proofing

From headcount forecast to floor plan, open plan versus cellular offices, expansion routes and the cost of being wrong: the practical guide to space planning for a growing business.

Start with a forecast, not a lease term

The first mistake growing businesses make is renting to match today's headcount. In eighteen months you're either bursting out of the space or paying for excess.

Begin with a three-year headcount forecast: where will you be in 36 months? What teams will you add? How will the work mix change? Build that scenario into your space needs, and choose a lease term and growth options accordingly.

Open plan, cellular or hybrid: the right choice depends on your work

Open plan trades privacy for flexibility and lower cost per person. Cellular offices (private rooms) suit heads-down work, client-facing roles and high-concentration work. Many growing businesses do both: a core open area and a ring of small focus rooms.

Test your team's actual preference before committing to a floor. Remote work has changed what people value — some teams that assumed they'd hate open plan now prefer it for collaboration; others discovered they need quiet.

Growth paths: expansion, consolidation or relocation

When growth outpaces your space, three paths exist: expand on the same floor if available space exists; consolidate to a larger floor in the same building; or relocate. Each has a different cost and disruption.

Before signing, ask: can this building accommodate your growth? What are unused floors nearby? Is there a right of first refusal for expansion? The cost of moving is high — avoiding it once is worth real negotiation upfront.

Hybrid work and flex space: the evolution of office planning

If 30% of your team works from home on any given day, you don't need a permanent desk for every person. Hot-desking and shared focus rooms reduce square metres per headcount and lower rent.

But flex space requires discipline: unassigned seating works only if there's genuinely sufficient capacity, and people accept a mobile workflow. For many teams the result is better use of office space and lower cost per person.

The hidden costs of getting space wrong

Doubling headcount into insufficient space kills productivity: back-to-back meetings in a crowded reception area, no quiet space for concentration, and culture-draining commutes. The cost of that hit to output exceeds the rent saving by multiples.

Over-renting carries an obvious cost, but a smaller hit: wasted space is visible on the balance sheet. Many growing businesses tolerate 10%–15% excess space as insurance against the disruption of a mid-contract move.
