What was the surname of the architect who designed Balfron Tower in the East End of London?

Balfron Tower is a 26-storey residential building in Poplar, a district of the London Borough of Tower Hamlets in the East End of London. It forms part of the Brownfield Estate, an area of social housing between Chrisp Street Market and the A12 northern approach to the Blackwall Tunnel. It was designed by Ernő Goldfinger in 1963 for the London County Council, built 1965–67 by the GLC, and has been a Grade II listed building since 1996.

Balfron Tower was designed by architect Ernő Goldfinger and is associated with the Brutalist style of 1960s architecture. Goldfinger himself was pleased with the design and moved into flat 130, on the 25th floor, for two months in 1968. He and his wife threw champagne parties to find out what the residents liked and disliked about his design. He applied what he learnt to his design for the similar and more famous Trellick Tower in West London. Goldfinger's studio later added Glenkerry House on the same estate, complementing Balfron Tower and Carradale in style.
