Office and retail building

Google's UK headquarters, this building is located in the area of King’s Cross Central Development, close to Saint Pancras International Station.
The main characteristic of 6 Pancras Square is the impressing massing that has been sculpted to merge with its context. As a result, this fine work on the mass of almost 100m long by almost 50m wide and 52m high tackles the challenge of bringing natural daylight into the deepest part of the building, providing very efficient office spaces of great quality and high flexibility. Here it has been generated a typology of floorplates that is quite unique in London.

The technology

With a length of 100m by 50m in width and a height of about 52m, this building shows a surface of over 15,000 m2 of SSG unitised façades, compact double skin façades, internal atrium space, a huge atrium glazed roof and terraces balustrades. The typical module is 2000mm or 1000mm x 3850mm, the building features an alternation of low-iron glazing and bespoke fluted yellow terracotta thus creating a dynamic contrast. Impressive glass-to-glass corner units of considerable dimensions, 2400mm x 3850mm, which have been prefabricated in our workshop. The black anodised finishing of the external horizontal fin features highlights the complex architecture of the project and perfectly integrates this building inside the urban framework of King’s Cross Central Development. The ground floor and the first floor of West elevation (on side of Saint Pancras Station) consist of compact double skin façade, which has been bespoke designed to comply with the strict thermal and acoustic requirements of the specifications. The internal atrium consists of full height laminated glazing 2000mm high and it features black anodised aluminium feature fins of remarkable dimension. Spandrels and columns consist of sound absorbing micro perforated metal sheet, thus to increase the acoustic comfort in public areas.


Wilmotte & Associates - Jean Michel Wilmotte

Born in Soissons (Picardy) in 1948, Jean-Michel Wilmotte studied interior design at the Camondo school of interior design in Paris.
Just two years after graduating, he founded his own practice in Paris in 1975. His style influenced a number of personalities including François Mitterrand, who asked him to design part of his private apartments in the Elysée Palace in 1982. Soon after, the mayor of Nimes, Jean Bousquet, commissioned the redevelopment of the city hall and the Museum of Fine Arts.
Jean-Michel Wilmotte earned his degree in architecture in 1993, allowing him to work on large scale and to develop the concept of "interior design of cities", while maintaining the same attention to the use of "noble materials and extreme attention to finishes" notable in his smaller scaled works. Over the years, the practice has diversified and now operates primarily in five key areas: architecture, interior design, museology, urbanism and design. The attention to details allows Jean-Michel Wilmotte and his team to work from the smallest to the largest scale: moving from a house to a skyscraper, from a shop to a corporate headquarters, from a gallery of art to a museum, and from street furniture to urban design. At present the practice Wilmotte & Associates has 185 employees. It has now taken a clear international and multicultural dimension, with projects in over twenty countries around the world. The Firm is now established in four locations: one in Paris, one in Sophia-Antipolis, one in London and one in Seoul.
In 2005, the Wilmotte Foundation was created to promote the urban graft through the W Prize, with the goal of helping and encouraging young architects. In 2010, according to a study by UK magazine Building Design, the practice is listed in the world ranking of the 100 largest architecture firms.
