David Richmond & Partners has lost the commission to extend its storage building for the Tate galleries after it suggesting expanding the scheme.
The Tate decided to appoint higher profile practice Nicholas Grimshaw & Partners for the project after David Richmond won outline planning permission for his scheme in London's Southwark.
In the original masterplan, David Richmond added an extra 12,000 m 2to the brief by raising the height of the building to 11 storeys. But the changes raised the cost of the project and the gallery was obliged to advertise through the Official Journal of the European Communities.After interviewing a number of practices, it chose competing practice Nicholas Grimshaw & Partners.
'It's a huge waste of time and knowledge, ' David Richmond said. 'We know that store inside out. It's our own fault - we should have said we couldn't make the scheme any bigger. I'd like to think that maybe they're a little embarrassed.'
However, a spokesperson for the Tate said it had no choice but to advertise the project and that, although David Richmond had been a strong candidate to take the project forward, Nicholas Grimshaw & Partners offered them 'what we needed'.
