Green Building Design Group is inspired by the Protea flower — a plant that thrives in harsh conditions and complexity. We were founded in South Africa to help the built environment navigate the complexity of sustainability regulation, resource efficiency, and ESG reporting.

We support infrastructure, real estate, and manufacturing clients to meet sustainability regulations, improve energy and water performance, and align with ESG goals through practical advisory services and digital solutions.

Through the GreenBDG Foundation — a 100% black women-managed non-profit — we reinvest in skills development and inclusive growth in Africa's green economy, supporting youth employment, learnerships, and SMME development.
