Quai Ouest Building in Nancy

«If the architect’s role, since action seems to have taken precedence over reflection, consists of designing the vast majority of buildings without history, without depth, almost ready-to-wear, then the one I was given to design in Nancy falls, on the contrary, into the realm of haute couture.» Anne Démians

Quai Ouest Building

Nancy, A Modern City for Over Three Centuries
Throughout the various periods of its urban development, Nancy’s vision always preceded its architectural commissions. The city suburbs were initially attributed to the original castle town, and in the eighteenth century, a message of unity was asserted at the annexation of Lorraine to the Kingdom of France. And this was an opportunity to highlight the ducal power around an exceptional architecture (classified as a UNESCO World Heritage Site). At the beginning of the twentieth century, the architecture in Nancy successfully integrated the richness of the École de Nancy in its constructions, just as it was able to promote new ideas on building and construction in the footsteps of the architect and designer Jean Prouvé, who was also mayor of Nancy after the Liberation. This identity and legacy continues today with the reconquest of the riverbanks of the Meurthe: the city of the twenty-first century.

Quai Ouest Building

Nancy or the Requirements of an «Exceptional» Urban Partition
This project is unusual, not only because it is located five hundred metres away from the world famous Place Stanislas. It reflects an ambition that – had it not been integrated into its DNA from the outset – would have resulted in the creation of a banal building without meaning or history. The heaped impertinence of Quay Ouest reveals firstly the demands of the mayor of the time, André Rossinot, now President of the Greater Nancy Agglomeration. Secondly, the overlapping interests of a company, Pertuy Construction, eager to show its commitment to urban inclination, which includes the ethical desire to (re)combine architectural creativity with the sustainability of a modern building with low energy consumption. In other words, Quai Ouest represents the synthesis of political energy with the commitment of a private developer.

Quai Ouest Building

Quai Ouest and the Meurthe Riverbanks
Quai Ouest is remarkable for its stainless steel outer shell and its 650 oblong windows like eyes watching the city. This 10,000 square meter building – on an island that has 28 000 – includes offices – including the Pertuy headquarters, a subsidiary of Bouygues Construction – a residential hotel and shops. Located on the outskirts of Nancy, this former industrial wasteland of the twentieth century and of the Canal is at the very confluence of Charles III’s city of Nancy and the new districts of the Meurthe riverbanks : 300 hectares contained within city-scale infrastructural boundaries in the process of urbanization that extend the reaches of the city by offering a new contemporary centrality.

Quai Ouest Building

Quai Ouest was previously the site of a gasworks. The site was sanitized, receiving an award by ADEME for its exemplary nature. Right on the edge of the banks of the Canal, it is at the intersection of the old city and the new city marked by Alexander Chemetoff’s Water Gardens and the alignment of modern buildings. It is also located at the culmination of the historic commercial centre of Nancy drawn by the St Jean and St Georges streets now crossed by the tramway.

Quay West dares to offer a contemporary articulation of diversity based on a delicate balance and coordinated architectural accordance and discordance.Like most of the principle buildings of old Nancy, the materials there are light in colour, they reflect and complement without literal imitation. The volumetrics respond and challenge, echoing the transversal altimetry.

Assessment
Because of the disorganisation of the spaces along the Canal, and this on a significant scale regarding the existing neighbouring heritage, Quai Ouest aligns itself with Nancy’s historical past and reinforces the naval front contributing to recomposing an urban clarity. The volume of the building researching unity also resonates with those sectors that marked Nancy’s public spaces since the eighteenth century such as the Opera or the L’Hôtel de la Reine close to City Hall and the Place Stanislas.

Why a Single Volume?
As the fusion operates horizontally between functions, the scale sought for this street angle does not need to rise above the height of adjacent buildings of the surrounding neighbourhood. The single volume can remain comfortably within the maximum prospects and heights imposed. This controlled height facilitates the internal articulation of offices altimetry (held at R + 5) which includes the headquarters and residence of Pertuy Construction (maintained at R + 4) and functions with their optimum floor height ( 3.35m for offices and 2,74m for apartment hotels). This measure also creates a balance with residential buildings (in progress) and existing neighbouring offices.

Ultimately, the single volume rises or compresses itself to induce spatial dynamics in resonance with the site. The outer envelope itself accompanies this unique movement to reveal shop windows, office reception areas and hotel receptions. As for the Opera and the L’Hôtel de la Reine, the diversity melds into the same vibration as the full openings.

The Internal Courtyard
The transcription of the diversity is evident in the interior patio lit by the changing reflections of the sky shimmering in stainless steel. This shared and sheltered communal space is directly connected to the café / dining room on the ground floor.

Communal Spaces The functional diversity that combines offices, a tourist residence and businesses allows for new exchanges. People working here can stay here, passers by can meet and hold meetings here. All will have access to the shops that have long been absent on this part of the historic trade route.

Car Parks
There are only 88 parking places available (half as many as the place’s potential). These are attributed to the hotel and offices, with the exception of Pertuy Construction. The corporation’s management deliberately wishes to revise the lifestyle trends and operations of its employees by encouraging them to use public transport and to share electric vehicles for their business travel within the urban community.

Quai Ouest’s Compact Design
Quai Ouest’s compact design allows for a simple volume without any instability / awkwardness. While respecting a flagstone to flagstone / tileto-tile height of about 3.35m, technical and environmental choices allow a ceiling height of about 2.70 meters. The partitioning is free, on a 2,70m framework. Its compactness is a source of energy saving, material saving and maximizing the surfaces and spaces. Its pure form provides a flexible, standard and economic construction. The high windows allows daylight to penetrate into the heart of the building, the lower windows offer users an immediate visibility into the city.

The oval and curved shapes of the outer envelope, the facets and edges fluidly cover and extend the volume reaching the frames and floors, suggesting their function.

The material, stainless steel in its natural colour, oscillates between white and grey depending on the angle of vision and the light. To create the 650 oval opening shapes, Cirmad developed specific tools, namely, resin window moulds obtained from automotive technology. These modules have to be positioned with great precision in order to receive the stainless steel cladding.

The Stainless Steel Envelope
Placed as close as possible to the structure, the stainless steel contributes to the unity of the structure and its inertia / momentum. The reduction of energy consumption is based on the performance of the envelope and on its technical installations. Energy performance is secondary to the reduction of heat loss in winter and optimization of solar energy
especially in summer. The inertia of the building is partly due to the full and empty zones of the partition but also to the windows that influence the thermal effect and redirect daylight into the interior. The openings, arranged more or less regularly in a variety of situations, stretch out into curved shapes covering this envelope seamlessly.

Laurent Mourey: «The stainless steel envelope is exemplary, but creating it was not easy. Instead of seeking international expertise, Pertuy Construction consulted the metalworkers of Lorraine. This expertise exists there and is of the highest quality. The family business, Le Bras Frères de Jarny Meurthe et Moselle, was finally chosen to manufacture this stainless steel cladding. It was the first time Pertuy Construction attacked a stainless steel facade of this complexity, but it is used to working on ‘impossible’ projects and ended up by buying up the company as a subcontractor « The stainless steel envelope comes from the workshops of the Le Bras Company (1954), a French traditional family business known for its interventions on historical monuments (the Louvre, the Arena of Arles, the Metz Cathedral, etc), but also for its digital tools for cutting and custom work, and computers for drawing (CAD and DAO).
