Not just a tower

Damp in East London today, but went out for a walk after work. Sometimes you can guess what inspires architects.
The ventilation tower is Grade II listed, and the listing describes it as ‘the principal work of Terry Farrell when he was briefly employed at the LCC between September 1961 and March or April 1962. Their curved form was inspired by Oscar Niemeyer's work at Brasilia, then first appearing in the architectural press. Farrell compares the romantic structure of these very industrial buildings with the rugged machine aesthetic subsequently adopted for housing and office buildings in the Poplar area’.
