Our Team
Gustav de Necker
As a professional architect with over 13 years of experience, I bring a deep understanding of design, construction, and client needs. I know firsthand the challenges homeowners, developers, and business owners face when sourcing aluminium doors and windows. My role at SiON is to bridge that gap, helping clients make the right product choices for their projects, with confidence and clarity.
Beyond my architectural background, I hold an MBA from Henley Business School, which strengthens my ability to align great design with sound business practices. This combination of expertise means clients not only get excellent products, but also clear guidance through the entire procurement journey.
Supported by In2itive (Pty) Ltd, SiON Advanced Apertures' aim is simple: to supply products of outstanding quality, backed by reliable service and lasting client relationships.
