The house derives its historical significance from its association with its previous owner, Thomas Spence Leask, well known as the "Father of Wolmaransstad". The alteration which were made in the 1880s and after 1900 to the original house which was bult in the 1870s, add to the architectural value of the house. The visits to the house by important political figures such as President Paul Kruger and General JC Smuts, also enhanced the historical importance of the building, presently known as the Thomas Leask House Museum.
