Start with the team
List current headcount, expected attendance, growth assumptions and the kinds of work each team performs. A desk count alone misses meeting rooms, support areas and the space between them.
Test the whole floor
Ask for alternative layouts that show circulation, visitor routes, meeting capacity, storage and pantry provision. Compare how the building core and daylight affect each option.
Check the building requirements
Request fit-out guidelines, access arrangements, services information and submission procedures from building management. Record the assumptions that still need a site survey.
