Paris-based LAN Architecture won the competition organized by ICF Novedis to design the block 4.2 of the new Cardinet-Chalabre urban development zone in Paris, France. More images and architect’s description after the break.

The major urban interest of Ilot 4.2 lies in its position: it will act as a fulcrum between Boulevard Pereire and the new ZAC (Urban Development Zone), creating a kind of transition between ‘black and white photograph’ Paris and the more extensive, three-dimensional city beyond.

Ensuring this transition was the core concern underlying our strategy, which involved trying to understand the fundaments of the Haussmanian typology.

We regard our proposal as a tribute to Paris, to an architecture defined by the city’s specificity and logic, but with the additional demand of having to provide solutions to current and emerging problems.

The project’s conception is based on the regularity of its façade. The interplay of matter and transparency defines the envelope of the ensemble, which for urban planning reasons has to take up the entire plot, and therefore have the same ground plan.

Each apartment is organised around a large loggia, an extension of the interior living space outside. In winter the loggia can be closed to create an additional living room, despite the cold. In summer the loggia helps ventilate the interior. The arrangement of the loggias creates an interplay between matter and transparency across the facade. Clad with wood, the loggias become its recognisable elements, enlivening the regularity of the windows, so that the building, seen from a distance, expresses itself from within, like a colour chart.

The regularity and size of the openings and the ceiling height render the building’s definition in terms of use ambiguous, and the choice of structure reinforces this. Only the facades and circulation core are load-bearing, leaving maximum freedom for the arrangement of each floor. The building can therefore change use in the future when required.
