In the heart of Amsterdam South, where railroad lines, subway and city traffic converge, a new landmark has recently appeared: the Amsterdam South Connection. This landmark building connects two branches of the city’s heating system and at the same time forms an architectural beacon for travelers entering the city from Schiphol Airport. The project is conceived as a sculpture: technically sophisticated, but also visually inviting.
On a triangular site completely enclosed by infrastructure, a huge water buffer with associated pumps and pipes was housed in a semi-transparent glass shell. This gives the building an almost ethereal appearance, while perforated metal sheets and substantial steel columns emphasize its industrial function. This creates a tension between lightness and robustness.
The floor plan is shaped like an isosceles triangle with rounded corners. On the roof are solar panels that contribute to the energy supply and reduce the ecological footprint. The control room was strategically placed on the roof and deliberately kept under Schiphol’s radar, underscoring the careful incorporation of the design.
Steel construction and corrosion protection in a demanding environment
Hot-dip galvanized steel, supplemented by duplex systems, was deliberately chosen for the support structure. This choice of material was motivated both aesthetically and technically. Hot-dip galvanizing provides extremely durable protection against corrosion and is essential in a building with highly variable temperatures and humidity levels. It also guarantees a long service life with minimal maintenance requirements. The steel column structure surrounding the water buffer is designed to function independently of the thermal operation of the facilities, ensuring long-term structural integrity.
The consistent use of hot-dip galvanized steel throughout all building parts – from hall to stairwell and buffer – creates a uniform architectural image. Combined with the glass and dark green metal band, this results in a powerful and durable statement. Not surprisingly, the Amsterdam South Connection was awarded both the National Glass Award and the National Steel Award. To crown it, the project won the 2025 Zinkinfo Galvanizing Award in the Buildings category.
