Story

A harmonious blend of minimalism and functionality Building F in Lyon the principles of efficiency and adaptability within the urban fabric of the ZAC Confluence district. Designed by Vera & Associés, this three-story structure, with a modest footprint of 14 x 23 meters, is a flagship of the Sollys project. The building's architecture is characterized by a unified design ethos, where nothing is superfluous, and every element serves a purpose. The ground floor, with its generous 4.50-meter ceiling height, hosts a café/bar that opens onto Place Hubert Mounier, enlivening the area opposite the contemporary music venue at the Marché Gare. The eastern side features a lobby that connects the street to a landscaped courtyard, leading to the office floors above. These floors offer open-plan workspaces that maximize natural light and urban connectivity, with flexible layouts that support various uses. The top floor features a meeting room with expansive windows framing views of local landmarks, complemented by a large terrace accessible to all building occupants. The terrace, adorned with planters, offers panoramic views of the neighborhood and beyond. A distinctive exterior staircase, combining metal and wood in the Chambord style, enhances the building's façade and , echoing the historic staircases of old Lyon. The building's concrete structure, optimized for both strength and aesthetic, integrates meticulous detailing, such as rainwater harvesting and precise concrete core layouts. Designed with bioclimatic principles, Building F leverages its orientation and the shadow of a nearby tower to manage solar gain, with external blinds facilitating natural ventilation. The interior showcases raw concrete and exposed technical systems, providing a spacious feel with 3.30 meters of clearance under the slab. An active slab system, powered by green gas cogeneration, efficiently regulates the building's temperature, supplemented by finned radiators and ceiling fans.
