Siège Orange Guinée

Construction of the new ORANGE headquarters in Guinea, a flexible building for a scalable company.

Located in the heart of the growing Koloma business district, the project aims to transform the site into a central hub for Orange’s influence. The challenge was to design an iconic, high-quality, and unique architecture while respecting the social and environmental issues present in Guinea.

The project includes reception areas, a conference hall, a company restaurant, a fitness room, and fully flexible office spaces.

The overall volume consists of two wings connected by a central section. A series of exterior walkways reinforce the link between the two built volumes. At the center, a shaded patio is accessible from all levels via various pathways: corridors, terraces, and footbridges.

Design Intentions – Conceptual Approach

Workspaces

The central part of the project houses the main core, which includes vertical circulation, technical areas, sanitary blocks, and all common spaces: lounge-coffee area, reprographics, archives, and large meeting rooms. The exterior walkways create a true connection and facilitate movement between the two wings of the building. They are present on every floor. Footbridges located at the ends of the wings further strengthen the connection between each part of the building. Present on every other level, they give life to an inhabited patio, creating both functional and aesthetic dynamics within the project.

Office Floors

The office floors offer complete flexibility and freedom in the layout of the various spaces. Benefiting from natural daylight, the organizational scheme defined by the architectural concept is simple and efficient. Open spaces, such as collective office areas, are located on the inner side of the wings, with direct access to the walkways. More enclosed spaces, such as meeting rooms, are distributed along the outer edges of the wings. This layout allows for maximum flexibility in the collective office areas, with the possibility of reconfiguring partitions according to evolving needs.

Landscape

At both the building and site scale, significant emphasis is placed on planted areas and vegetation. Greenery is present throughout the site's perimeter as well as on the building itself, at multiple levels. Planted strips form a vegetative belt at the base of both indoor and outdoor parking levels. These green spaces provide shaded areas for the entire surface parking lot.

Facades

A first layer of concrete—simple, raw, and elegant—is complemented by a second “filtering” skin. The facades feature fixed vertical metal fins in a pastel gold tone, giving the project a refined and balanced color palette within a context of warm, reddish hues. The distinctive and major advantage of this system lies in its effectiveness in managing daily solar gain. Positioned at a 90° angle to the façade, the fins provide protection from nearly all direct solar radiation.

The role of vegetation in cities, especially in hot climates, is essential for regulating heat, improving air quality, and enhancing residents' well-being.

A Strong Vegetative Presence

The Base

The building anchors itself to the ground like a tree with roots. Its base includes two parking levels, integrated into the terrain with densely planted buttresses. This creates a raised forecourt, shielded from the street, and visible as a layered landscape: ground covers, banana trees, medium-sized and tall trees.

The Fault Line

A fault line cuts through the base, connecting the building to the ground and opening the parking levels onto a garden. This tropical undergrowth features flowering plants, tree ferns, and tall Eucalyptus deglupta trees, whose colorful bark and light foliage form a canopy that filters light and softens the building’s height.

Suspended Gardens

Terraces host suspended gardens—natural fragments between earth and sky. Designed for well-being, they extend shared spaces with wind-resistant plants suited to above-ground cultivation: palms, bamboo, and tropical flowering species.
