In the late 1960s, the adjoining cottage–a deceased estate–was purchased for £6,000 and later, in August 1971, a two-storey building at 222 Petrie Terrace was added to the complex for $16,000. The cottage, at number 206, was renamed after Cor Boogaart, a workshop manager for the theatre for 27 years. The property at number 222 housed the theatre's wardrobe department and rehearsal space until its sale in 2011. Cor Boogart Cottage, having previously been used as a rehearsal venue, now houses the wardrobe division and construction workshop downstairs. The previous two rehearsal venues were renovated between 1976 and 1978 at the same time as the construction of the theatre's current office and bar. The Cor Boogaart Cottage was again refurbished following the sale of 222 in May 2011.
