Office Area Per Person: A Practical Guide to Getting the Numbers Right

Most businesses size their office based on headcount. They count the people, find a space that fits them, and sign the lease. The problem is that headcount alone doesn’t tell you how much space each person should have. It doesn’t account for how your team works, what mix of spaces they require, or whether everyone will be in on the same day. Get the number wrong in either direction and the cost shows up quickly: wasted floor area on one end, an environment that quietly undermines productivity on the other.

This guide is written for businesses planning a new office, renegotiating a lease, or weighing up whether a conventional lease still makes sense against flexible workspace alternatives.

Start With Strategy, Not Square Footage

Getting office sizing right starts not with a floorplate but with a clear picture of what the business needs now and where it’s headed. Working through four reasonable questions before any square footage calculation begins will put that picture in focus.

Organisational Strategy

Is the business centralising its workforce into a single location, or distributing teams across multiple sites? Does the office need to function as a permanent headquarters, a collaboration hub that people come to for specific purposes, or a drop-in base for a team that’s largely remote? Each of those models implies a different floorplate, a different ratio of desk to meeting space, and a different total area requirement.

Business Objectives

A company in active growth mode needs different space than one that is consolidating, restructuring, or managing headcount carefully. The lease should reflect the trajectory of the business, not just the current number of people in it. Signing for a space that fits today’s headcount without accounting for where the business will be in two years is one of the most common and expensive planning errors in commercial real estate.

Future Needs

Factor in planned hiring, the possibility of contraction, and the likelihood that hybrid or remote policy will shift within the lease term. An office space in Singapore that fits well today can become a constraint or a cost within 18 months if neither growth nor flexibility was built into the decision.

Layout Requirements

Before translating anything into square footage, determine what types of space the business actually needs. The ratio of private offices to open desks, the number and size of meeting rooms required, the provision of collaboration zones and breakout areas: these decisions shape the floorplate calculation significantly, and they should be made before a single building is shortlisted.

What the Minimum Office Space Per Person Looks Like?

While Singapore doesn’t prescribe a statutory minimum office area per person, international workspace standards such as Germany’s ASR A1.2 (Technical Rules for Workplaces) are widely referenced as a practical baseline by space planners and occupiers globally. Under ASR A1.2, the recommended minimum is 8 sqm of floor space for the first workstation and 6 sqm for each additional one. Environments designed to the minimum tend to be functional on paper and difficult in practice: compliant enough to pass inspection, but not productive enough to retain the people working in them.

The figure applied in practice sits between 10 and 12 sqm per workstation, which represents a realistic working range for most business types. That per-desk number, however, is only part of the calculation. An additional 25 to 40% should be added on top of the per-person figure to account for traffic routes, communal areas, and shared infrastructure.

This is where most businesses underestimate. Corridors, kitchens, reception areas, bathrooms, and meeting rooms aren’t free space. They consume significant floor area that must be factored into the total before a floorplate is selected. A business that calculates for 20 desks at 10 sqm each and stops at 200 sqm will find itself short the moment shared space needs are mapped against a real building plan.

The Factors That Move the Number Up or Down

Office Layout

Layout is a deliberate design choice with direct space implications. These four primary configurations each carry a different per-person footprint.

• Open Plan (70–100 sqft Per Person): The most space-efficient layout, suited to collaborative, high-density teams. Acoustic management is the key trade-off; without quiet zones and soundproofing areas, the density that makes it efficient can also make it counterproductive.
• Traditional Office (120–150 sqft Per Person): Individual enclosed offices with shared corridors and meeting rooms. The higher per-person footprint reflects the privacy and focus that certain roles and industries require as a baseline, not a preference.
• Hybrid Workspace (50–80 sqft Per Person): The most efficient option for businesses with a genuine hybrid policy, designed around activity-based working where not all staff are in simultaneously. It only works if attendance is genuinely distributed; applied to a full-time team, it will be undersized from day one.
• Executive-Heavy (150–200 sqft Per Person): Reflects organisations where senior leadership occupies dedicated private suites and headcount is weighted toward management rather than operational staff.

Industry

Industry type is one of the strongest predictors of actual space requirements, because it determines the mix of private, collaborative, and client-facing areas a business genuinely needs.

• Banking and Finance (150–180 sqft Per Person): Private offices, client-facing meeting rooms, and compliance-sensitive areas that cannot be open plan all push the per-person figure well above the desk count alone.
• Legal Firms (150–200 sqft Per Person): Partner offices, large consultation rooms, and document storage consume considerable floor area beyond what a headcount-based calculation would suggest.
• Tech and Startups (80–120 sqft Per Person): Open plan configurations with hot-desking and collaborative zones are the norm. Space efficiency is a priority in environments where culture tolerates density.
• Trading and Sales (80–100 sqft Per Person): Dense open floor configurations with minimal private office allocation, reflecting a model that prioritises desk density and real-time team communication above individual workspace.
• Corporate Headquarters (150–200 sqft Per Person): Executive suites, boardrooms, formal reception areas, and visitor facilities all add substantial floor area to the per-person baseline before a single operational desk is counted.
• General Commercial (100–140 sqft Per Person): A mixed model of open plan and enclosed offices that suits businesses without a single dominant space type, offering a practical middle ground across functions.

JustCo: Right-Sized Workspaces Across Singapore’s CBD

Once a business has worked through the sizing framework, a second question follows: does a conventional lease actually serve that need, or does a flexible workspace produce a better outcome?

A conventional lease fixes the sizing decision at signing. If the business grows faster than expected, the space constrains it. If it grows slower, surplus floor area costs money every month. JustCo removes that risk. Flexible membership structures mean businesses can scale up or down without renegotiating a lease, and the footprint in use can reflect actual attendance rather than a headcount assumption made at signing.

The workspace options across JustCo’s Singapore CBD locations cover the full range: hot desks, private offices, dedicated suites, and meeting rooms bookable on demand. The JustCo app ties this together operationally, allowing members to book desks and reserve rooms directly so space in use on any given day matches who is actually in. For businesses that need a prime CBD address without committing to a full floor, JustCo puts that address within reach at a fraction of the conventional lease obligation.
