The architect of this impressive, radical and rare piece of English modernism was Owen Williams, part-architect and part-engineer, Williams had designed a number of bridges, factories and office blocks, most notably the Boots Factory in Nottingham and the Daily Express Building on Fleet Street, before embarking on Dollis Hill Synagogue. Using reinforced concrete with the concrete cast in-situ, the building was as technologically advanced as any of William’s engineering projects. He boldy expressed the buildings function through the geometric forms of the fenestration, representative of the Magen David and the Menorah respectively. The building was derided by the congregation and Williams gave some of the fee back to them as a result. Although heavily altered, particularly on the inside, it remains a powerfully singular piece of architecture.
