Office Space for 100 Employees: Avoid Mistakes, Plan Smarter
Planning office space for 100 employees isn’t just about desks. It’s about productivity, comfort, compliance, and cost-efficiency. Whether you’re in Sydney, Melbourne, Canberra or anywhere in Australia, the question is the same: how much space do we actually need to work well?
Let’s break it down based on Australian guidelines, industry best practices, and what works in the real world.
What’s the Minimum Office Space Per Person in Australia?
In Australia, Safe Work Australia and the Property Council of Australia recommend a minimum of 10 m² per employee. This includes not just desks, but circulation and common areas.
For 100 staff, that equals a minimum of 1,000 m².
This figure assumes a very basic, open-plan setup with no private offices, limited meeting rooms, and no breakout zones. It meets compliance but may not support productivity.
Ideal Office Space Requirements by Workspace Type
Depending on your layout and work model, your actual space needs may vary:
| Office Layout | Area per person | Total for 100 people |
|---|---|---|
| Open-plan only (desks and aisles) | 10–12 m² | 1,000–1,200 m² |
| Open-plan with collaboration and storage | 12–15 m² | 1,200–1,500 m² |
| Hybrid (hotdesking with breakout areas) | 8–10 m² | 800–1,000 m² |
| Traditional (private offices and meeting rooms) | 15–20 m² | 1,500–2,000 m² |
Sample Office Layout for 100 Staff (1,200 m²)
If you’re aiming for a functional, modern workplace, here’s a sample breakdown Aurora might recommend:
| Space Type | Area | Notes |
|---|---|---|
| 80 Workstations | 500 m² | 6–8 m² per desk including aisles |
| 20 Hot desks or flex-use | 80 m² | For casual or rotating staff |
| 4 Meeting rooms | 100 m² | Mix of 4-person, 6-person, and 12-person rooms |
| 2 Quiet rooms | 20 m² | For calls or focused work |
| Kitchen and breakout | 150 m² | Communal eating and recharge area |
| Reception | 50 m² | Optional front-of-house space |
| Storage, lockers, print | 100 m² | Includes utility zones |
| Bathrooms | 100 m² | As per building code |
| Circulation areas | 100 m² | Includes aisles and accessways |
Total: approximately 1,200 m²
Factors That Impact How Much Space You Need
Team Size vs. Seating Ratio
Are all 100 employees in the office daily, or do you operate a hybrid model? Hot-desking and staggered attendance can reduce your space needs by 20 to 30 percent.
Office Functions
Do you need client-facing zones, showrooms, warehouse access, or dedicated collaboration areas? These will increase your total commercial office layout footprint.
Growth Plans
Planning for scale? Build in extra space for future staff or modular layouts that can adapt to changing needs.
Workspace Styles
Modern workplaces favour open and flexible layouts with fewer assigned offices and more informal project zones, breakout areas, and quiet rooms.
