An urban superblock

Le Monolithe, Lyon (FR)

he mixed-use, urban superblock Le Monolithe includes an unusual combination of owner-occupied and rented apartments, council flats as well as holiday flats, offices and retail spaces. In addition to its extraordinary architecture, it is also noteworthy for its sustainable planning.

Lyon is expanding its centre with the development of the Confluence quarter. Large-scale urban projects are being implemented on a 150-hectare site on the southern part of the Presqu’île peninsula. Large blocks of buildings that are home to 660 apartments and 15,000 square metres of office space have been built at Place Nautique alone. One in particular stands out from the crowd thanks to its striking design – Le Monolithe.

Five building sections, five architects

Le Monolithe consists of five building sections arranged in a row, each designed by a different architecture firm. Although Le Monolithe is one complex, the facades of the five segments have very different surfaces and colours. The apartments and offices feature flexible floor plans and can be individually adapted to the different needs of the users. A long, continuous inner courtyard with an elevated, publicly accessible room that offers a great view of the city, the new marina and the park is a central element.

A sustainable building

In addition to its extraordinary architecture, Le Monolithe is also noteworthy for its sustainable planning. For example, renewable energy accounts for 80 per cent of the complex’s energy consumption, and only environmentally friendly materials were used. The rainwater is treated, and there is an efficient spatial arrangement, good thermal and sound insulation and an energy concept that includes heat storage, solar cells, insulated glazing and natural ventilation.

Geberit Know-how

3,000 metres of Geberit Mapress Carbon Steel pipes were used for connecting the solar collectors on the roof to the water heating system. The Mapress Carbon Steel system offers high corrosion resistance and is a perfect solution for closed hot water circuits.

«We opted for carbon steel pipes because pressing is much faster and therefore also more economical than soldering.»
