The entire building relies on the idea of lightness and movement.
Hikari is a project designed by the Japanese architect Kengo Kuma, in conjunction with CRB, a Lyon design agency. The project is located at the newly designed waterfront in Lyon, France, and it is conformed of three different buildings. Each building offers a different program:
- Higashi (‘East´ in Japanese) is a 5,500-m² office building.
- Minami (‘South’ in Japanese) offers 38 apartments with a floor area of 3,400 m².
- Nishi (‘West’ in Japanese) a mixed-use building with offices, each 2,600 m², and four residential penthouses with 700 m².
The three buildings share a 1,000 m² of retail space on the ground floor.
Kuma aligned his main concept with Herzog & de Meuron ideas, the ‘urban development plan’ and the ‘basic box like buildings.’ Kuma took the stage, and sculpted the buildings using large triangular notches to convey sunlight deep inside the spaces of the building. For those reasons, Kuma named the conjunction of these three buildings Hikari, which in Japanese means ‘light’.
Minami -central building- exceptional luminosity comes from the extensive exterior glazing, which eliminates the borderline between the interior and exterior. The glazing provides a peek of the interior retail spaces, garden, and the entrances to the offices.
On the other hand, the two adjacent buildings share glazing and local stone which makes up the exterior grey façade. The angles on the facade change gradually, providing different expressions of light and shadow through the day. Finally, the spaces harmonize with the brilliance reflection of the river located right across.
The three buildings rely on the idea of lightness and movement, consistently with Kengo’s vision of contemporary architecture inspired by nature. The internal courtyard which adapts to the building geometry, reflects the same idea of nature and architecture.
Hikari is an example of environmental innovation and sustainability. The complex incorporates three different sources of renewable energy.
- photovoltaic panels on the roof and façades of the residential building
- geothermal energy
- co-generation power plant
