In 2019, the Ycone tower marks the return of Jean Nouvel to Lyon. Located in the heart of the La Confluence district, the Ycone residence is easily identifiable by its light yet powerful silhouette.

Ycone’s atypical façade was born out of the search for an alternative to a honeycomb underside to absorb wind vibrations.

La façade atypique d’Ycone est née de la recherche d’une alternative à une sous face en nids d’abeilles pour absorber les vibrations du vent.

A large-scale project, Energiesprong is 160 occupied homes to be renovated in record time.

The entire production is carried out off-site on a metal frame. It includes the structure, insulation, siding, finishing, integration of windows, shutters…

Only the installation of the blocks and their connection is carried out on site in about 2 days per house. A real feat for occupied housing.

The cladding used is Techline 8mm self-cleaning and depolluting chromatic cladding.

It is in the very heart of the Carré Sénart, in the commune of Lieusaint, that the Théâtre-Sénart was established in 2015.

The Agglomération de Sénart called upon the architectural firm Chaix & Morel et Associés.

The façade of the Théâtre-Sénart is the emblematic element of this project. Visible from afar, it makes the theater shine as the cultural center of the Carré Sénart plain.

This spectacular volume hides the technical installations and ventilation extractions, which are installed between the waterproofed roofs and the perforated exterior envelope, making it invisible.

The façade is made of pre-painted grey aluminium, stamped and/or perforated depending on the location, and implemented by a system of 150×150 cm cassettes. 8 patterns are applied to each side of the cladding, creating a pattern of perforations of different sizes.

The shade of gray is soft, very close to the natural shade of the anodization. A PVDF layer is added as a pre-coating for a highly reflective result. With the help of an indirect LED lighting system, the perforations of the façade let the light through. At nightfall, the building lights up with many sparkles, creating movement and vibration.
