Office Building rehabilitation by AZC

The Office Building project at 122 Avenue Général Leclerc, in the Silly-Gallieni neighborhood, in Boulogne Billancourt, is a complete renovation of an 70s office building. The aim of the action was to reconcile an apparent simplicity with a very high level of energetic efficiency.

The AZC studio was chosen to transform the office building at Avenue Général Leclerc, in Bolougne Billancourt, a French town in the Ile de France region, just 10 km away from the Paris center. The two office buildings are interconnected through the ground floor, which extends with a shared lobby and private spaces for business at south of it. The original facades, as was characteristic at the time of its construction, had very closely concrete fins and load-bearing columns. The architects’ aim was to open them by removing five out of six columns, getting a new glass facade for the most part.

Descripción del proyecto por AZC

The project consists of the renovation of an existing building of 10.544m² surface area in Boulogne Billancourt, the redesign of the facades, taking into account the overall structure, the renovation of the technical premises, and the optimization of office spaces.

The building required an architectural revival justified by the evolution of office uses as well as the energetic standards.
The issues of energetic efficiency were subtly approached, in the facades and facilities designs, by customizing solutions rather than simply applying current regulations brutally. The entire building’s facades were wiped entirely clean of all superfluous elements. The whole structure was consolidated with the aim of obtaining good stability and a full transparency (65% in glass).

The building’s new skin, is a double ventilated façade of slight thickness.
The idea of total flexibility was pursued throughout the uniform grid patterning of the facade paneling into 1.35k modules corresponding of the suspended ceilings, and through the electrical and technical “irrigation” of the offices by means of raised floors and suspended ceilings.

The building’s new image forms both out of restraint regarding the economy of means and the taking into account of the client’s expressed wishes and needs. Our proposition highlights generosity of space, light, comfort, and wellbeing. Today more than ever businesses are sensitive to the image their facades present to the world, as well as to the amount of comfort they can provide their employees.

Grégoire Zündel-Irina Cristea AZC

AZC Architectes is an architectural studio founded in 2001 by Irina Cristea and Grégoire Zündel based in Paris, France.

The studio was born out of the idea that the exploration of architecture and its techniques could help to improve the built environment. Their interest does not lie in the invention of concepts, they have always tried to realise buildings for real life needs.

Through competitions and direct commissions, the office has worked on more than a hundred projects of varied scales and uses. Most of its built projects are intended for a wider public; sports facilities, conference halls, office and residential buildings, some of which very specifically for vulnerable populations. They also have eight metro stations under construction, four of them in Paris and four in Rennes and studies for a new station in Lyon.

Most of their work has been published, exhibited, sometimes awarded and they have often been given the opportunity to speak on issues of sustainability, diversity and innovative techniques that illustrate all their commitments.

Irina Cristea, born in Bucharest, graduated from ENSA Strasbourg in 1995 and studied architecture at London South Bank University and Bucharest Ion Mincu institute.

Grégoire Zündel, born in Colmar, graduated from ENSA Strasbourg in 1995. He is a visiting professor at ENSA Strasbourg from 2004-2006.
