Who and when built the mansion is not precisely known, but it was owned by 15 proprietors, all prosperous, before it was purchased by the provincial government.[citation needed]
On 22 October 1693, Governor Simon van der Stel granted the 12 ha near Table Mountain as a homestead to the businessman Guillaume Heems. After just 2.5 years, the farm was sold to the Company's Garden botanist, surveyor, and gardener Henrik Bernard Oldenland. Upon his death, his widow sold it to the Fiscal Joan Blesius, who probably built the first house on the farm. In 1764, Johan Bräsler, originally from Copenhagen, purchased the farm. He built the current mansion from 1764 to 1788, planting native trees and growing fruits and vegetables there. Capt. Johannes Zorn owned it from 1799 to 1836. He expanded the farm by annexing adjacent land until it reached 79 ha, becoming a successful farmer who owned dozens of slaves and planted large vineyards. In 1809, Zorn was appointed magistrate.[citation needed]
On 21 December 1936, the Cape Province Administration (Afrikaans: Kaapse Provinsiale Administrasie (KPA) purchased the house as the official residence of the Administrator of Cape Province. The KPA repurchased the adjoining land from the historic estate.[citation needed]
