7 Bedroom House in Benmore Gardens

A Landmark Modernist Estate by Anthony Nol Slaven | Sandton, Johannesburg

This exceptional mid-century modern estate, designed, owned, and built by Anthony Nol Slaven, one of South Africas most respected modernist architects, represents a rare acquisition opportunity for international buyers and institutions seeking architectural significance, scale, and strategic positioning.

Set on approximately 4,500 sqm of established, landscaped grounds, the property offers approximately 870 sqm under roof, located minutes from Sandtons financial and diplomatic hub, yet enjoying a level of privacy and tranquillity seldom found so close to a major global business district.

Architectural Significance

Influenced by Frank Lloyd Wrights principles of organic architecture, the residence is characterised by strong horizontal lines, generous spatial volumes, and a deliberate integration with its natural surroundings. The design prioritises privacy, adaptability, and longevityqualities that resonate strongly with both institutional occupiers and long-term investors.

Anthony Nol Slavens international recognition is anchored by his design of the Regina Mundi Cathedral in Soweto, a globally acknowledged landmark of cultural, political, and spiritual significance. His private residence reflects the same disciplined architectural thinking, translated into a highly functional and refined living environment.

Now in its sixth decade, the property remains an exceptionally intact example of South African mid-century modern architecture, having been carefully maintained over the past 14 years.
