Gregory Katz proves that three times is a charm with his trio of concrete homes, which challenge the status quo in this quiet Johannesburg suburb. Read Full Article
Gregory and Caryn Katz are dwarfed beneath the cantilevered concrete overhang, which houses the bedroom on the upper level. The stackable glass doors that run beneath allow the house to open completely to the yard and swimming pool, soften the severity of the concrete, and blur the boundary between indoors and out.
The freestanding staircase was built three times before Gregory deemed it structurally sound—a tribute to the architect’s tenacity. The high-tech end result was achieved using small custom-made plastic reinforcing fibers. The galley-style kitchen with its bold use of color was Caryn’s choice. She fell in love with the name of a paint swatch called Canary Yellow and then left it to Gregory to fine-tune the exact hue.
Caryn was thrilled to discover that all her personal details look spectacular when offset against the solemnity of concrete. In profile, the freestanding staircase is the most outstanding design accent.
Cognizant of concrete’s excessive greenhouse gas emissions, Gregory built with the future in mind: The modular structure of his home could just as easily accommodate the demands of a nursery, restaurant, or office, as suggested by the various seating and dining arrangements situated throughout the house, particularly in the dining and living area. The space is outfitted with an Eames chair and an unfinished wood shelving unit and dining table. The room opens to the yard and pool, enhancing the room’s circulation to the outdoors.
