3XN Launches Mixed-Use Artistic Design for Parisian Neighborhood of La Défense | New
Featuring a program that combines a traditional office and hotel accommodation through two distinct volumes, connected along an east-west axis, which offer views of the adjacent towers of La Défense and the monumental monument of Johan Otto von Spreckelsen. Great Arch.
“As the first shape you encounter when arriving from La Défense, this building had to be eye-catching and dynamic,” explains Kim Herforth Nielsen, founding partner of 3XN. “The faceted facade and the moving volumes make it a star in the lively district. The concept — two distinct but complementary designs — is unique in the region.
The project uses a cladding of semi-reflecting aluminum panels to distinguish the Hotel OKKO as an uninterrupted mass, while the office structure of its partner InDéfense splits into smaller shapes, extruding to “open up the long site and narrow to its surroundings and add depth to the facade.”
A closed agora located between the two volumes is punctuated by a wall control and a spiral staircase. Inside the office function, another spiral staircase frames its entrance and offsets the north-facing atrium with widened landings meant to facilitate conversation and team building among its fellow tenants.
“Stairs connect more than floors; they connect people,” adds Nielsen. “In this project, they are open and visible on all floors and weave in and out of the building, making them a social and visual connecting element and making you more aware of your surroundings when you you move into the building.
The rest of the structure includes a handful of additional social spaces, with exterior terraces located leading to the crown of the building and connected again by a network of exterior spiral staircases. The rest of the copper-colored facade offers what 3XN calls a “dynamic push-and-pull game” through its design of receding overhangs that welcome biophilic elements typical of contemporary office design intentions on productivity and well-being. to be workers.
Juxtaposed to this is the nine-story, 184-room hotel function, which includes a ground-floor restaurant and 3,230-square-foot lounge. It features interiors designed by Studio Catoir, while the “offset” effect described by Nielsen on its exterior is achieved by angular tinted aluminum cassettes that offer an alternately metallic or transparent appearance to exterior viewers depending on the time of day. of the day or location.
The facades of the two volumes are designed according to high level acoustic performance standards. The cassettes include perforated side panel openings for ventilation without any intrusive visible frames. “On such a long and visible site, the facade had to combine beauty and functionality,” shares Nielsen.
The whole project will obtain WELL Silver, BREEAM Excellent and Very Good certifications. SRA Architectes accompanied its site plan, which joins the extension of the RER E and the new M15 Les Groues station, seen as the source of a greater expansion of the district which will materialize in the coming years.
