Port House in Antwerp
Port House in Antwerp named ‘Best Refurbished Building’ at MIPIM Awards 2018
Design: Zaha Hadid Architects
Following its commendation by the Architectural Review’s ‘New into Old’ awards in December 2017, Port House in Antwerp has been named ‘Best Refurbished Building’ at the MIPIM Awards 2018.

Established in 1991, the MIPIM Awards are presented at the world’s leading conference of property and real estate, recognising the most outstanding and accomplished projects across the globe.
Port House in Antwerp repurposes, renovates and extends a derelict fire station into a new headquarters, connecting the city with the vital activities of its port.
With 12km of docks handling 26% of Europe’s container shipping, Antwerp is the continent’s second largest port with ambitious targets for future expansion to meet the Europe’s growth over the next century.
Working with heritage consultants Origin, ZHA’s historic analysis of the fire station revealed its unrealised tower. Port House is a composition of a new volume that ‘floats’ above the old building, respecting each of the existing facades and completing the verticality of the original design’s unbuilt central tower. The new extension points towards the city, connecting Antwerp with the port on which it was founded.
Surrounded by water, the new extension’s façade is a glazed surface that ripples like waves and reflects the changing tones and colours of the city’s sky. This perception of a transparent volume, cut to give the new building its sparkling appearance, reinterprets Antwerp’s moniker as the city of diamonds.
With constant references to the River Scheldt, the city of Antwerp and the dynamics of its port, married with the successful renovation and reuse of a redundant fire station–wholly integrating the old firehouse as part of the new headquarters–Port House will serve the port of Antwerp well through its planned expansion over future generations.

With 12 km of docks, Antwerp is Europe’s second largest shipping port, serving 15,000 sea trade ships and 60,000 inland barges each year.
Antwerp handles 26% of Europe’s container shipping, transporting more than 200 million tonnes of goods via the ocean-going vessels that call at the port and providing direct employment for over 60,000 people, including more than 8,000 port workers. Indirectly, the Port of Antwerp ensures about 150,000 jobs and has ambitious targets for future expansion to meet the continent’s growth and development over the next century.
In 2007, when the former 1990s offices of the Port of Antwerp had become too small, the port determined that relocation would enable its technical and administrative services to be housed together, providing new accommodation for about 500 staff. The port required a sustainable and future-proof workplace for its employees, representing its ethos and values in an ever-expanding local and international arena.
As the threshold between the city and its vast port, Mexico Island in Antwerp’s Kattendijk dock on Quay 63 was selected as the site for the new head office. The waterside site also offered significant sustainable construction benefits, allowing materials and building components to be transported by water, an important requirement to meet the port’s ecological targets.

Following the construction of a new fire station with facilities needed to service the expanding port, the old fire station on the Mexico Island site – a listed replica of a Hanseatic residence – became redundant and relied on a change of use to ensure its preservation. This disused fire station had to be integrated into the new project. The Flemish government’s department of architecture, together with the City and Port authorities organized the architectural competition for the new headquarters.
Zaha Hadid Architects’ design is informed by detailed historical research and a thorough analysis of both the site and the existing building.
Marc Van Peel, president of the Port of Antwerp, said: “There was only one rule laid down in the architectural competition, namely that the original building had to be preserved. There were no other requirements imposed for the positioning of the new building. The jury was therefore pleasantly surprised when the five shortlisted candidates all opted for a modern structure above the original building. They all combined the new with the old, but the design by Zaha Hadid Architects was the most brilliant.”
Working with Origin, leading heritage consultants in the restoration and renovation of historic monuments, ZHA’s studies of the site’s history and heritage are the foundations of the design which firstly emphasises the north-south site axis parallel with the Kattendijkdok linking the city centre to the port. Secondly, due to its location surrounded by water, the building’s four elevations are considered of equal importance with no principal facade. ZHA’s design is an elevated extension, rather than a neighbouring volume which would have concealed at least one of the existing facades.
ZHA and Origin’s historic analysis of the old fire station also highlighted the role of its originally intended tower – a grand, imposing component of the fire station’s Hanseatic design. Its bold vertical statement, intended to crown the imposing volume of the building below, was never realised.
These three key principles define the design’s composition of new and old: a new volume that ‘floats’ above the old building, respecting each of the old facades and completing the verticality of the original design’s unrealised tower.
Like the bow of a ship, the new extension points towards the Scheldt, connecting the building with the river on which Antwerp was founded.
Surrounded by water, the new extension’s façade is a glazed surface that ripples like waves and reflects the changing tones and colours of the city’s sky. Triangular facets allow the apparently smooth curves at either end of the building to be formed with flat sheets of glass. They also facilitate the gradual transition from a flat façade at the south end of the building to a rippling surface at the north.
While most of the triangular facets are transparent, some are opaque. This calibrated mix ensures sufficient sunlight within the building, while also controlling solar load to guarantee optimal working conditions. At the same time, the alternation of transparent and opaque facade panels breaks down the volume of the new extension, giving panoramic views of the Scheldt, the city and the Port as well as providing enclosure.
The façade’s rippling quality is generated with flat facets to the south that gradually become more three-dimensional towards to the north. This perception of a transparent volume, cut to give the new building its sparkling appearance, reinterprets Antwerp’s moniker as the city of diamonds. The new extension appears as a carefully cut form which changes its appearance with the shifting intensity of daylight. Like the ripples on the surface of the water in the surrounding port, the new façade reflects changing light conditions.
The old fire station’s central courtyard has been enclosed with a glass roof and is transformed into the main reception area for the new Port House. From this central atrium, visitors access the historic public reading room and library within the disused fire truck hall which has been carefully restored and preserved. Panoramic lifts provide direct access to the new extension with an external bridge between the existing building and new extension giving panoramic views of the city and port.
The client requirements for an ‘activity based office’ are integrated within the design, with related areas such as the restaurant, meeting rooms and auditorium located at the centre of the upper levels of the existing building and the bottom floors of the new extension. The remaining floors more remote from the centre, comprise open plan offices.

Collaborating with services consultant Ingenium, ZHA developed a sustainable and energy-efficient design reaching a ‘Very Good’ BREEAM environmental rating. Despite the challenges of integrating with a protected historic building, high standards in sustainable design were achieved by implementing effective strategies at each stage of construction.
A borehole energy system pumps water to a depth of 80m below grade in over 100 locations around the building to provide heating and cooling. In the existing building, this system uses chilled beams. In the new extension, it uses chilled ceilings. Waterless lavatory fittings and motion detectors minimise water consumption while building automation and optimal daylight controls minimise artificial lighting.
With constant references to the Scheldt, the city of Antwerp and the dynamics of its port, married with the successful renovation and reuse of a redundant fire station – integrating it as a fully-fledged part of its headquarters – the new Port House will serve the port well through its planned expansion over future generations.
Marc Van Peel said: “The architectural style of the original building, a replica of the former Hansa House, recalls the 16th century, Antwerp’s “golden century.” But now above this original, a contemporary structure in shining glass has been built, which I am sure, represents a new golden century for Antwerp.”
