Craft Homes' Riverstone Wetland Estate earns Edge green certification
The development in Fourways meets Edge standards with projected cuts of 37.5% in energy, 20.8% in water and 36.1% in embodied material energy.
By Felo News Desk · Published
Craft Homes’ Riverstone Wetland Estate in Fourways has secured preliminary Excellence in Design for Greater Efficiencies (Edge) certification from the Green Building Council South Africa, according to a Bizcommunity report dated 14 Oct 2026.
What happened
The Edge certification, an innovation of the International Finance Corporation, recognises projects that achieve at least 20% reductions in energy consumption, water use and embodied energy compared with local standards. Riverstone comfortably exceeds those thresholds, with projected savings of 37.54% on energy, 20.76% on water and 36.07% on embodied energy in building materials. Final certification will be granted after the development is completed.
What the reports add
The article notes that Riverstone is among a small group of South African residential projects to obtain this milestone. It also links the certification to Craft Homes’ recent success at the International Property Awards, where the estate was recognised for sustainability alongside sister projects Iconic Melrose and Bryanston Country Estate.
What was said
Reinier van Loggerenberg, chief executive officer of Craft Homes, said: “Riverstone was built around the idea that you don't have to choose between a beautiful, liveable estate and a genuinely sustainable one. Getting the Edge numbers independently audited and approved is proof that the wetland‑first design decisions we made on paper actually hold up in practice.” He added that the International Property Awards judges recognised the estate’s sustainability and that the certification provides the technical backbone for that recognition.
How it came about
The Edge programme combines an online platform, a green building standard and a certification system used in more than 170 countries to create a financially credible case for sustainable construction. By meeting the programme’s criteria, Riverstone demonstrates how residential developments can integrate environmental considerations—such as rehabilitated wetlands in Magaliessig—while delivering measurable efficiency gains that could unlock financial benefits for qualifying homebuyers.
