Tate Modern extension gave boss 'sleepless nights'

摘要

Tate director Nick Serota has spoken of the sleepless nights the delayed £260m Herzog & de Meuron-designed and Mace-built extension has caused him, writes Elizabeth Hopkirk. The twisted, 10-storey Switch House will open on 17 June next year, he announced last week, four years later than originally planned. Serota also confirmed the project cost has jumped £45m to £260m, attributed to build cost inflation. "This is a complex building, designed by a team who are, in my view, one of the best architects in the world," he said.
