Architectural Systems Designed for Modern South African Homes
At SION Advanced, we believe the systems behind a building should be as refined as the architecture itself.
We specialise in premium architectural systems including aluminium glazing, garage doors, balustrades, and integrated hardware solutions, carefully selected and developed to meet the demands of contemporary South African homes and developments.
Our focus is not simply on supplying products, but on delivering complete systems that combine aesthetics, durability, functionality, and long-term performance.
Our Story
SION Advanced was created from a simple observation: many architectural systems available locally were not meeting the standards expected in modern residential and commercial projects.
Too often, products lacked consistency, integration, durability, or the refined detailing required for contemporary architecture. Hardware varied from project to project, systems were poorly standardised, and long-term performance was often overlooked.
We saw an opportunity to bring together globally competitive systems and apply them within a South African context — combining premium materials, engineered components, and architectural thinking to create solutions that perform as well as they look.
Today, SION Advanced continues to focus on delivering systems that are carefully considered, technically sound, and aligned with the evolving expectations of modern architecture.
Who We Are.
SiON is led by architect Gustav de Necker, bringing over 13 years of experience in design, construction, and client delivery. With an architect’s understanding of how buildings work, and an MBA-driven approach to execution, Gustav ensures clients receive not only premium products, but also clarity throughout the specification and procurement journey.
SiON is strategically supported by In2itive (Pty) Ltd, an investor in high-end businesses with sound leadership, specialist products, and clearly defined markets. This partnership reinforces SiON’s long-term commitment to premium delivery, disciplined execution, and trusted client relationships.
Gustav de Necker Founder & Lead Architect
Our vision: clarity + performance = confidence for architects.
We translate design intent into performance‑driven apertures so architects can specify with confidence.
What We Believe
We believe quality is found in the details.
We believe architectural systems should enhance the spaces they form part of — not simply fill an opening.
We believe products should be designed with real-world use, longevity, and integration in mind.
We believe premium systems should not only look refined on day one, but continue to perform for years to come.
And above all, we believe thoughtful design, engineering, and consistency create better buildings.
