The Tea Building is in East London and part of a group of warehouses on the edge of the City that have been lovingly refurbished. This former Lipton Tea warehouse dates back to the nineteenth century and was purchased by a company called Derwent for £22m in 2000, then given a £6m makeover. It's now worth more than £50m.
The design strategy was to create high-style and high-quality public spaces, then do as little as necessary - allowing creative tenants to take advantage of the possibilities which the tough industrial spaces offer.
I love the big "TEA" sign atop the building!
