How Much Office Space Do You Actually Need?

One of the first questions that comes up when planning an office move or refurbishment is:

How much space do we actually need?

It sounds straightforward, but it’s often answered too quickly—and based on assumptions that don’t fully reflect how a business operates.

Traditionally, space was calculated around headcount.

A certain number of desks, a few meeting rooms, and the rest would follow.

In practice, it’s far more nuanced than that.

1. Why Headcount Alone Isn’t Enough

Headcount can be a useful reference point, but it should never be the primary driver of space planning.

On its own, it doesn’t reflect how a business actually functions.

Different companies, and even different teams within the same company, operate in very different ways.

Some require:

• quiet, focused work environments

• dedicated individual workstations

• secure storage and support areas

Others rely more heavily on:

• collaboration

• informal interaction

• regular team sessions or town hall-style gatherings

Some teams are highly interactive and energetic. Others are more structured and task-focused.

These differences have a direct impact on the type and amount of space required.

2. How Work Patterns Shape Space

The way people use the office today is more varied than it used to be.

There is often a mix of:

• in-office and remote work

• individual and collaborative activity

• formal and informal interaction

This means that space needs to be flexible enough to support different ways of working, rather than being based on a fixed formula.

3. What Should Drive Space Decisions

A more effective approach is to start with how the business operates at both a company and team level.

Instead of asking:“How many people do we have?”

The better questions are:

• How do different teams work day to day?

• What types of spaces do they actually need?

• How often are people in the office?

• What balance is required between focus, collaboration, and shared space?

When these questions are properly considered, the space can be shaped around real usage.

4. The Cost of Getting It Wrong

When space is not aligned with how a business actually functions, the impact goes beyond layout inefficiencies.

It affects how the business performs.

A workspace that does not properly support the way teams operate can:

• slow down productivity

• limit effective collaboration and communication

• create friction in day-to-day workflows

• impact staff wellbeing over time

These effects are not always immediate, but they build over time.

The space begins to work against the business rather than supporting it.

That’s where the real cost sits.

Not just in how the space looks or feels, but in how it affects the overall success of the business operating within it.

5. A More Considered Approach

Before committing to a space, it’s worth taking the time to properly understand how it will be used.

This can include:

• reviewing how teams currently operate

• identifying different types of space required

• testing layouts against real working scenarios

When this is done properly, decisions around size, layout, and configuration become far more aligned.

Office space should not be defined by a single metric.

It should be shaped by how the business and its teams actually function.

When that thinking is done upfront, the result is not just a space that fits, but one that works.
