Port Authority Building (Antwerp)

The Port of Antwerp is Europe's second largest shipping port by traffic, handling 26% of Europe's container shipping. In 2007, port authorities determined that a new location would enable its technical and administrative services to be housed together, providing new accommodation for about 500 staff. The new Port House would centralize operation into one building, improving efficiency. The lower section of the building was a disused fire station, and a protected replica of a former Hanseatic house. Thus, it could not be demolished, and the fire station had to be integrated into the new project. According to , president of the port of Antwerp, “There was only one rule laid down in the architectural competition, namely that the original building had to be preserved." Several studies, such as a historic survey and an investigation into the historical values of the site, were conducted. Van Peel stated that five shortlisted candidates all opted for the addition of a modern structure above the original building, and the design by Zaha Hadid Architects was chosen. This was considered appropriate as the original fire station was intended to include a tower. The construction of the expansion began in October 2012 and the building was officially opened in September 2016. == Design ==

The expansion of the building is located directly above the renovated fire station. It has a glass-covered facade with a protruding bow and the surface of the facets of a diamond facing the Kattendijk dock. This is also a reference to Antwerp's association with the diamond industry. The exterior of the "diamond" consists of transparent and opaque triangular facets. This allowed the architects to control the amount of sunlight entering the building. The placement of the facets mimics the nearby River Scheldt. Project manager Joris Pauwels stated that concrete pillars and 900 tonnes of steel hold the glass workspace above the former fire station. A bridge level joins the two structures and gives employees a 360-degree view of the public square and the Scheldt below. The design of the building took energy efficiency into account, reaching a 'Very Good' BREEAM environmental rating. A borehole energy system pumps water to a depth of 80 metres below grade in over 100 locations around the building to provide heating and cooling. The company Cegelec was in charge of installing and unifying the energy networks of the two buildings, with the insertion of plastic pipes to achieve an energy storage volume of 12 cubic metres. The restored and preserved fire engine hall contains a public reading room and a library. The whole building has a total floorplan of 12,800 square metres, with 6,600 square metres in the refurbished fire station and a further 6,200 square metres in the extension. == Accessibility ==

The port house has two areas of private parking. The entrance of the underground parking area is at the Mexicostraat, with charging points for electric cars. The second parking area is roughly two minutes from the Port House, on the Merantistraat. Across Antwerpen-Centraal railway station is a tram stop where you can take tram 24 (Silsburg-Havenhuis) to its final stop in front of the Port House. == Awards ==

The Port House was nominated as a finalist for the A+Awards in the commercial office mid-rise category. == Gallery ==
