Some readers may be aware that we have outgrown our palatial offices at 16 Hanbury Street in London's fashionable east end, and as a result we're taking additional space directly opposite on the other side of the road. The extra room will be great – working conditions currently resemble the London Underground during rush hour – but being split across two buildings isn't ideal. So we wanted to find a way to link the two buildings. Our first idea was a bridge across the street. But we couldn't get planning permission for that. So instead a team of W+K 'moles' has started work on a tunnel beneath Hanbury Street, linking the two sites at basement level. Work is progressing well:

Our plan is for the tunnel not just to be a functional throughfare but to be a feature that reflects our  values and way of working: a portal, if you will, representing the journey from idea to execution. The finished thing will look something like this:

But it will be in colour.
