The Orange Cube by Jakob + Macfarlane

The "Cube Orange" agency & nbsp; Jakob + Macfarlane Architects stands in the Docklands area of ​​Lyon, on the banks of the Saône. Housing the head office of the Cardinal Group real estate developer and a showroom of contemporary design for RBC, the hollow cube is coated with a

second perforated aluminum skin.

On this project, Jakob + Macfarlane Architects specify:

"The ambition of the development of docks Saone Lyon side, developed by BNS (Waterways of France) in partnership with the Caisse des Depots and SEM Confluence as part of Confluence is to reinvest this area industrial heritage by integrating architecture and cultural and commercial programming.

These docks originally composed of former warehouses (the Sugar, Customs, Salins, the Harbour Master), Crane, functional elements associated with river and stream, mutate into an area of ​​experimentation to create a new landscape articulated towards the river and the hills toward which they turn.

The Orange Cube project is designed as a "& nbsp; & nbsp cube;" orthogonal, in which architects have carved a void that meets the needs of light, air circulation and views. It pierces the empty building horizontally from the banks of the Saone upwards to the roof terrace.

Slightly offset from the existing hall (the Salins, formed of three arches), the cube is backed but stresses its autonomy. In a grip of 29 x 33 m, it is designed on a regular grid of concrete columns over 5 floors. A light facade with an apparently random composition of openings is complemented by a perforated aluminum on-facade with pixelated patterns that accompany the flow of the Saone. The orange color refers to the minium, color on recurrent industrial port sites.

Jakob + MacFarlane subjected to the cube to create this vacuum, a series of volumetric disturbances related to the subtraction of three volumes conical disposed at a front corner, the roof and at the entrance. These disturbances generate places and relations between the building users, the site and the light flows in a regular program offices.

A first course comes in direct visual relationship with the vaulted structure of the hall of Salins, its proximity and its shape braced. It connects the two architecturally elements and free space on a double height, protected within the building.

A second elliptical course, monumental, breaks the beam-column structural regularity of the building on four levels at the corner of the façade facing the river. This perforation, born of the encounter of two curves, establishes a relationship to the diagonal angle. It generates in the depth of the volume a huge atrium around which have a series of balconies connected to the office floors. The façade plane is thus shifted inwardly. It then builds a new relationship to light and vision, as well as from the inside from the outside. This creates a highly dynamic gutting relation to the building which, according to the position of the viewer, never has the same geometry.

Tertiary plateau benefit of light and views to different floors with balconies available at each level. Each tray takes advantage of its access to its balconies and views of a new type of usability, meeting place and informal exchanges.

The search for greater transparency and light transmission on the plates brings elegance and lightness to workspaces.

The top floor is recessed treated with a large terrace from which you can enjoy the whole panorama of Lyon Fourvière and Lyon-Confluence.

The project is part of the overall sustainable development approach initiated by the SEM and Confluences Tribe and as such meets the Specifications Environmental Charges defined in the context of the development of this area including:

Optimizing the design of facades to reconcile thermal performance and visual comfort with a U bat & lt; 0.7 W / m2 K and a Daylight Factor (KRF) of 2% on almost all offices & nbsp ;; thermofrigorifique production by heat pumps to water table and the new hygienic air exchange with high efficiency recovery calories from exhaust air.

The building is linked to future large terraces connected to floating docks. "
