Today I visited the View at the Shard – fantastic views from the centre of Southwark (and a wonderfully historic cathedral to visit as well).
Lend Lease (yes, the Australian property development company) has established an impressive European HQ at Regent Place. They occupy three floors in a new corporate precinct and have based their design on the theory of activity-based workplaces. It was both beautiful and very smart in the decisions that have been made. The CEO and all of the  leadership team have desks and workspaces in the open place desk area. I will let the images speak for themselves.
… and they do have desk areas (note the proliferation of vegetation -very controversial in the world of office design due to cost of upkeep) and bright surfaces to ensure strong, even light for all desks.
