The BCO commissioned Savills and Arcadis to answer this and to consider the role the BCO has played in driving, facilitating or supporting changes in the office.

The full report is clustered around five broad themes:

• design, fit-out, technology and the worker

• performance and sustainability

• specification and construction

• planning, design and place

• the office as an asset.
