The extension design takes precedent from the detailed existing facade and the recurring theme of diamonds and arches which are present in both the faҫade and decoration. Founded by Joseph Taylor in 1852, Taylor & Challen produced presses for the metal trades including the manufacture of complete plants for the minting of coinage and machinery for the manufacture of guns, cartridges and the processing of gunpowder into various forms. In the 20th century it supplied

goods such as wheels, radiators, clutches and brake drums to the motor trade. Our proposals to revive this Grade II Listed building include a rooftop extension, the restoration and conversion of the four storey manufactory fronting Constitution Hill and the two storey 5 bay workshop building on Henrietta Street.
