The Radical Transformation of Résidence La Violette

Ardèche Habitat and Atelier Montérémal Architectes have succeeded in a major rehabilitation project of Résidence La Violette. This mid-20th century housing development, which was very outdated, was renovated to improve appearance, comfort and energy effiency. Rockpanel Colours façade panels gave the 102 housing units (spread over 8 buildings) a completely new look.

A ventilated façade construction

The existing facade of Résidence La Violette posed significant challenges for the installers and designers as it was not a standard facade, but rather an exterior comprising prefabricated concrete walls with an irregular surface that includes diamond tip forms. As such, it was determined a ventilated facade fixed to the existing structure was the best technical solution. The resulting design solution includes a total of 3000m² Rockpanel Colours façade panels in different colours. The boards were produced in special lengths for this project, which helped the installer make a cost-effective offer.

From old-fashioned to colourful

Architect Claude Mounier explains he chose Rockpanel products due to their durability and UV resistance, as well as the broad range of available colours and designs. “The most impressive thing about this project is the before/after comparison. The building now looks really modern and contemporary with a colourful, cheerful facade, whereas before it looked very old-fashioned and sad,” says Mounier.

Demolition versus renovation

In many cases, the demolition of a mid-20th century modern building such as this could at first appear easier than renovation. It is however important to determine whether a building can be economically renovated. Reusing an existing structure not only reduces construction time but also eliminates excavation and foundation costs. Furthermore, in this instance, the Rockpanel facade solution here results in a building envelope that is not only thoroughly contemporary in appearance, but also achieves high thermal performance. For the owner, this means savings in construction costs and for tenants up to date living and increased comfort. A win-win situation for all.
