Ernö Goldfinger’s Balfron Tower has been upgraded to a Grade II* listing.

The block was built in 1965 as part of a move towards high-rise living - with Ernö living at Flat 130 for two months in 1968 to prove the desirability of the block.

The upgrade from a Grade II listing comes shortly after The Wharf reported that Poplar HARCA has been accused of trying to push businesses and social tenants out of its Brownfield Estate properties.

A National Trust spokesman said: “Balfron Tower, along with its younger sister Trellick Tower, is a testament to a particular moment in time when a vision of a utopian post-war Britain coincided with Brutalism – an architectural movement that indelibly changed the landscape of our urban environment. This was intended to be a heroic architecture that sought to offer the best of design to the masses and to free people from the condemned slum housing and poor conditions still prevalent in 1960s Britain.”

Reasons given for why it has been upgraded:

Authorship: It is part of a major exponent of the European Modern Movement in Britain and built by an architect of international standing

Architectural interest: It is the precursor and model for Erno’s modernist high-rise towers, and a manifestation of his rigorous approach to design and of his socialist architectural principles.

Materials and construction: concrete aggregate, exceptionally fine bush-hammered concrete finishes

Planning interest: Corbusian-inspired interlocking arrangement of flats and maisonettes, three per bay, served by enclosed access galleries at every third floor, linked to a separate service tower which included community facilities, sports and hobby rooms.

Degree of survival: A little-altered building that demonstrates le Corbusier’s views on spatial planning, where Balfron Tower has a particularly strong planning, visual and aesthetic relationship with Carradale House and Glenkerry House

Social and historic interest: Phase one of an London County Council mixed development, principally of high rise blocks, designed to re-house a local community within a carefully planned integrated landscape

Group value: Balfron Tower has strong group value with the low-rise and high-rise elements of the estate, most notably with Carradale House, and the space within which it stands.
