[2] Following the Dissolution of the Guilds in 1547, ownership of the building passed to Thetford Corporation when it received its royal charter from Queen Elizabeth I in 1574.

The doorway within the porch was flanked by Doric order columns supporting a frieze, while the bays to the left and right contained round headed sash windows which were also flanked by Doric order pilasters supporting the frieze.
