Balfron Tower is a 26-storey residential building in Poplar, Tower Hamlets, East London. Built in a Brutalist style, 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 is stylistically similar to Goldfinger's later Trellick Tower in London.
Carradale House (1967–70) is an adjacent, unique, modernist building, also designed by Ernő Goldfinger and Grade II listed. The two buildings appear to be natural extensions of each other, linked by style and design, with the long, low form of Carradale House complementing the height of Balfron Tower. All flats have dual window aspect and large south facing balconies, allowing plenty of natural light, and decorated with natural wood panels on the sides.
Goldfinger's studio later added Glenkerry House on the same estate, complementing Balfron Tower and Carradale in style.
The building was given Grade II listed status in March 1996, followed by Carradale House in 2000 to spare them from demolition. Carradale and Glenkerry Houses were also included in the Balfron Tower Conservation Area, designated in 1998. The listing continues to attract comment, especially in view of the failure of another nearby Brutalist estate, Robin Hood Gardens, to obtain the same protection.
