D4 Architecture is a client-centred architectural practice based in Benoni, Gauteng, South Africa, led by experienced principal Marc Dufourq, a University of the Witwatersrand graduate with over two decades in the profession. The firm partners closely with clients to deliver thoughtful design solutions across residential, commercial, and high-density building projects, blending practical functionality with contemporary architectural expression.
The studio provides a comprehensive range of architectural services that span new homes, commercial buildings, complex residential developments, additions and renovations, and consultancy services. Beyond traditional architectural design, D4 Architecture also offers 3D renderings and visual fly-throughs, shop fitting and bespoke furniture design, site evaluations and project reports, and can serve as principal agent through the construction process.
Under Marc’s direction, the practice has contributed to projects not only throughout South Africa but also in Swaziland, Malawi, and Nigeria, showcasing design work that is responsive to both local context and client requirements. The firm’s portfolio reflects a balance between functional spatial planning and aesthetic clarity, with residential commissions that optimise light and flow as well as commercial schemes that prioritise efficiency and user experience.
D4 Architecture is increasingly engaged with sustainable design practices, and Marc holds accreditation to support existing building green-star rating assessments through the Green Building Council of South Africa’s tools—adding environmental performance insight to the studio’s architectural expertise.
Located on Starlight Street in Farrarmere, Benoni, D4 Architecture continues to expand its presence in the built environment by delivering projects that combine thoughtful design, technical rigour, and strong client collaboration from concept through completion.
