On the same site as the present Curator's House, a single-storey timber building was constructed in 1872 for the Christchurch Domain Curator, John Armstrong. By 1919, the original wooden building was in poor condition and the current Curator's House was built in its place in 1920. The Architectural firmCollins and Harman were employed in 1919 to design a two storied brick house with a slate roof. It was finished in 1920 and the house was the residence for the curators of the Botanic Gardens up until 1984. In 2000 it was renovated into a restaurant.
