Office leasing tools

Three practical tools help you estimate space, leasing cost, and fit-out budget before requesting options or visiting buildings. Results are planning inputs; GRES should confirm the final brief against the actual building.

Plan your office brief from real numbers.

Three connected tools help you estimate space, calculate total leasing cost, and frame a fit-out budget before requesting options or visiting buildings.

Space

Estimate office space

Estimate the space requirement from team size, attendance and room needs. This is an initial planning guide and does not replace a test-fit plan.

Peak daily attendance

For a hybrid model, use the number of people typically present at the same time on the busiest day, not the weekly average.

Space standard

Support-space needs

Adjustments

If the building already quotes Gross/Rentable area, set the Net-to-gross allowance to 0% to avoid double counting.
