New Joburg Development: Thirty Keyes

WORDS Amelia Brown

Thirty Keyes, the new flagship residential development within the Keyes Art Mile in Rosebank, Joburg, is a collaborative partnership between developers Tomorrow Co, architects StudioMAS, interior designers Hesse Kleinhoog, and multidisciplinary designers Fieldworks.

The building, which joins the neighbourhood’s existing architectural landmarks including the Circa Gallery and The Trumpet, also designed by StudioMAS, offers residents access to the restaurants, galleries, boutiques, stores, showrooms and all-round energy of Joburg’s creative high street.

Central to the development is the concept of courtyard living. Drawing on classical precedents of open-air arcades, atria and colonnades, residents can escape from the urban bustle into a lush shared space that is “primed to encourage community, yet invites privacy and pause”.

According to the team, this dialogue between public and private space is at the core of Thirty Keyes’ architecture, interior design and lifestyle. “Thirty Keyes is the essence of a traditional courtyard, reimagined in a contemporary guise. It’s a means for us to connect the public and the private in a way that is both poetic and practical,” says Pierre Swanepoel, partner and architect at StudioMAS Architecture and Urban Design, of the courtyard, which will be planted with indigenous highveld grasses, shrubs and perennials.

Thirty Keyes comprises an initial release of 55 units, followed by 85 second-phase apartments, that cater to different lifestyle and budget considerations. There are compact single-level apartments with a master bedroom and balcony or an additional library room or guest bedroom; others that are double level and have courtyard access; some that feature private roof top gardens and uninterrupted views; and an “Atelier Series”, which facilitates living and working by combining a studio or showroom space with a solo apartment.

The interiors are described as graceful, function-friendly and primed for personal expression. Andrea Kleinloog, partner and interior designer at Hesse Kleinloog, says, “Above all, the interiors have been designed to respond to the everyday realities of living now. These are spaces intended to invite sanctuary, creativity and community.”

From security and smart access control to dedicated concierge support and high-speed connectivity, the Thirty Keyes’ team has considered all aspects of modern city living. To find out more, go to
