When the Tate Gallery split in half at the turn of the millennium, John Miller was the architect who turned its original Millbank home into Tate Britain. The new development, Tate Modern, carved out of the brick cliff of the former Bankside power station by Herzog & de Meuron, attracted larger crowds. But in architectural terms the remodelling of the somewhat underpowered classicism of Tate Britain by Miller and his wife and architectural partner, Su Rogers, was equally significant.
Miller, who has died aged 93, was allergic to the idea of iconic architecture. His approach to creating spaces for art was the opposite of the wave of attention-seeking and aggressive signature designs that have come to be associated with 21st-century museum building. Miller and Rogers added a sequence of new galleries to Tate Britain, increasing its size by a third, and created a handsomely proportioned new entrance, but made it seem as if almost nothing new had happened.
