Common Office Space Mistakes Businesses Should Avoid
Last Update: 22 September, 2026•Read: 7 minutes
Many businesses choose an office based on first impressions without closely reviewing what the lease actually entails. The space photographs beautifully, the rent looks competitive, and the location seems workable. Six months later, the commute is wearing on the team, additional costs have pushed the monthly spend well beyond the original budget, and the business is tied to a space it is already beginning to outgrow.
That is what makes choosing an office space deceptively difficult. The most expensive office mistakes are rarely visible during an initial viewing. They emerge once the space is being used every day: when meeting rooms are constantly occupied, the building struggles at peak times, employees find the journey harder or longer than expected, or the agreement leaves little room to respond when headcount changes.
The financial margin for error on these decisions is shrinking. JLL's 2026 Global Office Fit-Out Costs Guide found that office fit-out costs increased by roughly 2% to 6% globally over the previous year, with final costs also varying considerably by layout and specification. Meanwhile, CBRE's 2026 workplace benchmarking recorded 53% average office utilization but 80% at peak, a reminder that neither average attendance nor a simple employee-to-desk ratio tells you whether a space will actually work on its busiest days.
The real risk, then, is not simply making a poor choice. It is committing before you understand how the location, total cost, amount and type of space, building performance and agreement terms work together. The seven mistakes below are the ones worth catching before a promising office turns into an expensive constraint.
