[4] After high demand for the product led to expansion of the business, the directors decided to procure a social club for the workforce to be known as the Ronuk Hall and Welfare Institute.

[6] The social club was designed by Gilbert Murray Simpson in the Neo-Georgian style, built in red brick with stone dressings and completed in 1928.

The central section of three bays, which also slightly projected forward, featured a doorway flanked by Doric order pilasters supporting an entablature.

[10] In the late 1950s the directors of Ronuk entered into negotiations to dispose of the company's assets and business; the social club was bought by Portslade Urban District Council, which was seeking larger offices.

The Ronuk business was sold to Newton, Chambers & Co.[11] After appropriate conversion work had been carried out, the building was re-opened by the chairman of the council, Robert Shields, as Portslade Town Hall on 2 September 1959.
