The iconic Barbican Handrinse Basin was designed for the Barbican Estate in London. Chamberlin, Powell and Bon were appointed architects for the Barbican scheme in 1960. The construction of the residential estate commenced during the 1960's and the first building, named Speed House, officially opened in 1969. The construction of the housing development continued throughout the 70's and the Barbican Centre was finally completed in 1982. The complex houses around 4000 people over 2014 flats.
