Renzo Piano's curvaceous new headquarters for the Jérôme Seydoux-Pathé Foundation are completed in Paris

Passers-by on the Avenue des Gobelins in Paris' 13th arrondissement may notice an organic-shaped 'creature' peeking above Auguste Rodin's sculptures on the façade of No 73. Snuggled within an old city block, its rounded body is covered in aluminium scales, reflecting the grey colour of Parisian rooftops. A grey roof was one thing that Sophie Seydoux, president of the Jérôme Seydoux-Pathé Foundation, insisted upon when discussing the design of the Foundation's new headquarters with its architect, Renzo Piano. 

Impressed by Piano's 2006 Morgan Library extension - an elegant addition to the dense fabric of Midtown Manhattan - Jérôme and Sophie Seydoux went directly to the Italian architect for the Foundation's new home. Piano had worked with Pathé before; his firm converted the 1920 Lingotto Factory building in Turin, home to one of its multiplexes. 

Built in 1869 as a theatre and transformed into one of Paris' very first cinemas in the early 1900s, 'Le Rodin' - the existing building on No 73, which was gutted and rebuilt internally - was the perfect match for the Foundation. Pathé is not only a major player in the film industry today, but its history developed in parallel with the history of the movie industry. 

A cinematographic empire born in 1896 from Charles Pathé's interest in the technical innovations of his time (notably Edison's phonograph and kinetoscope), Pathé had released over 9000 films by 1927. Its US branch reportedly produced a movie a day. All of them have been catalogued (although not all survived) in Pathé's vast archives, which comprise everything from business correspondence to photos from movie sets, a first-hand account of the beginnings of cinema as an art and an industry.

The new building - a highly anticipated new project by one of the most iconic contemporary architects - was an ideal choice of setting for our 2014 Architects Directory photo shoot. While it was in the late stages of completion earlier this year, we brought together 12 practices from the Directory's 20 emerging firms for a group portrait under its soaring glass roof.

When the Foundation's new headquarters are officially inaugurated in September, the building will host two key functions: a screening room for silent movies and a resource centre. 'Showing and explaining are the two things I'd like to do here,' says Sophie Seydoux, who plans to organise workshops for children to discover the materiality of movie making. Screening and exhibition rooms are housed in the lower floors, while staff and researchers will occupy the two upper levels, generously lit through the glass dome and clad in a warm, all-wood interior. The archives are sandwiched in the two floors in-between, at the building's heart. 

Having the entire demolition and construction process pass through the existing building's 5m-wide listed front façade gate was among the project's major challenges. Architect Thorsten Sahlmann, who worked on both the Morgan Library and the Foundation, explains that the building's new glass entrance facilitates the transition between the historic frontage and 'the creature'.

The project's reduced footprint (the theatre previously on site covered a larger volume) offers additional breathing space for the neighbours and even secures a courtyard garden, while the glass dome improves natural lighting in the adjacent apartment blocks. At Piano's firm, they are convinced that a project should not only react to the client brief, but also contribute to the city that surrounds it, and the new Pathé Foundation is a thoughtful response to both.
