LAN Architecture Completes 70° Sud Housing Project in Boulogne-Billancourt

Urban Insertion: 'The project fits in a environment very rich architecturally and in its materiality. We have therefore conceived of an architecture possessing a double character responding to the urbanity of the Yves Kermen and Emile Zola streets, and the landscape of the Grande Traversée.'

Compactness: 'The project is situated on a block with a constraining morphology and orientation. The lot is relatively small (839 m²) and of irregular shape. These issues enrichened our dialogue on compactness and on ways to approach it. The result is a piece of architecture that fulfills its role as a corner building and creates a clear distinction with the surrounding buildings.' (Photo: Julien Lanoo)

Street Facade: 'We brought forth a building with a clean and simple reading. The facades are lined with exterior balconies punctuated by steel boxes and glass openings, to lighten the impression of a mass.' (Photo: Julien Lanoo)

Details: '10 dwellings benefit from a 80 cm wide balcony framed by an inox steel box, extending from the interior living room and displayed throughout the façade in a random-like manner.' (Photo: Julien Lanoo)

Details: 'Large glazed openings, with exterior carpentry work in aluminum on the street façade and in wood and aluminum on the courtyard façade, create a linear purity.' (Photo: Julien Lanoo)

Details: 'Where the building is anchored to the ground, a copper skirt runs along the building, and is given visual correspondance to the balcony strips above.' (Photo: Julien Lanoo)

Housing units: 'Majority of the apartments are offered a double orientation. This flexibility was made possible by the bearing facade walls. On the highest floors, a few duplexes were given generous terraces.' (Photo: Julien Lanoo)

Energy: 'The compactness of the building, the number of floors, an 88% net habitable area to floor area ratio, thermal bridge breaks, the heating system, along with very strict auto-control procedures, have contributed to the obtention of the BBC-Effinergie label.' (Photo: Julien Lanoo)
