WINNER: ARCHITECTURAL CATEGORY
No. 1 Silo, V&A Waterfront
No. 1 Silo, part of the first phase in the Silo precinct development of
The V&A Waterfront, won the Architectural category. This 10-storey development
consists of an east and a west wing built on two levels of a mega-basement
covering the whole site.
Structural steelwork was the solution to provide slender support to the
façades, walkways, bridges, lifts and feature stairs, while economically extending
the cantilevers of the conventional post-tensioned slabs framing the atrium.
The roof of the atrium is positioned above the open volume area spanning 17
metres. A composite steel and concrete Bondek slab was designed to serve as
the primary support and waterproofing line to an accessible and functional roof.
Another critical design element of the atrium was the feature staircase that served
the five office levels.
Heritage requirements regarding the treatment, restoration and reinstatement
of the existing structures were of the utmost importance. Underpinning the
heritage silo and buildings constructed in the 1920s was a great challenge to the
structural engineers and contractor.
No.1 Silo has been awarded a 6-star rating by the Green Building Council of
South Africa. The development is the country’s latest – and largest - green office
building. It is only the second office building to be awarded this rating in South
Africa and the first in the Western Cape.
Hugh Fraser, representing the South African Institute of Architects on the
panel of judges said: “No 1 Silo, like all buildings, will be measured by the passage
of time, but steel ensures this should be an enduring contribution to the local
architectural community,” he concluded.
