The renovation of this building designed by a/LTA architects is located in the historic center of Vannes, in the Brittany region. Specifically, it is located at the intersection of rue Thiers and rue Carnot, near the village and backed by the city walls.

This is a project in which a bank has been transformed into an office building for the real estate agency for Groupe Giboire. From the initial construction, the original structure has been preserved except for the attic, which has been given a new style.
a/LTA architects studio designed the renovation of the building, which is composed of three floors and an attic, from which they have tried to make the most of it. For this, a large meeting room with access to a terrace has been established. Regarding the materials, on this last floor, you can see stainless steel cladding, which is also visible on the first floor. Therefore, it is an interior design that stands out for its transparency and luminosity.

As for the facade, it is especially striking for the materials that make it up. It was highlighted with curved glass on the two intermediate levels, which forms a game between the reflections of the city and the sky. This bet shows sobriety and finesse, accompanied by a complex structure already existing on the facade itself.
 

Description of project by a/LTA architects

This project involves the heavy restructuring of a corner building located at the junction of rue Thiers and rue Carnot, in the heart of the historic center of the city of Vannes. 

The existing building, R+2 plus attic, was a bank that we transformed into offi ces for Groupe Giboire. The aim is to set up a new commercial and real estate development agency. The location of the project is remarkable, close to the port, it is backed by the city walls dating from the 4th century. 

The original structure of the building has been preserved, except for the attic which has been given a new style. The fi rst fl oor "catches up" with an alignment on the street, large openings are created to allow the reading of the ramparts located in the court. It is clad with a stainless steel cladding that is also found on the attic. The original confi guration in angle (providing a real response to the articulation of the two streets), and the complexity of the structure of the existing facade, the bias was to choose the sobriety and fi nesse of the materiality. For this reason, the mineral facade was highlighted by a second curved glass skin located at the two intermediate levels. 

The combination of glass and stainless steel envelops the building and delicately slides it into the historic heart of the city. The redesigned facade plays with the refl ections of the city as well as those of the sky, which vary according to the time of day. 

The glass panels, which make up this pleated structure, are supported by stainless steel rails. An anodized aluminum frame allows the natural ventilation of this double skin. The upper part of this frame, which constitutes the acroterion, is made up of removable panels which make its maintenance possible. 

The interior design was guided by the idea of transparency and luminosity. The attic of the building hosts a large meeting room that gives access to a terrace with a view on the city and the port.
