Does any company preside over an uglier set of buildings than BT? Well, there’s now one less hideous eighties monolith to marvel at, with the complete refurbishment of the Angel Building in Islington. It’s almost unrecognisable with its glass and exposed concrete, and a new facade that restores the old line of the Georgian terraces. It’s also very sustainable, with a BREEAM “excellent” rating. Architect AHMM kept the project’s carbon footprint low by keeping the old concrete frame – which made it an ideal cover star for the Spring issue of Concrete Quarterly magazine, which I edit.
