BOUYGUES CONSTRUCTION BUILDS AN INNOVATIVE SUSTAINABLE NEIGHBOURHOOD IN PARTNERSHIP WITH THE PETIT-SACONNEX RETIREMENT HOME AND

THE LA FONCIERE REAL ESTATE INVESTMENT FUND IN GENEVA, SWITZERLAND

Losinger Marazzi, the Swiss subsidiary of Bouygues Construction, has finalised its proposal to build a highly innovative complex for the Petit-Saconnex retirement home in Geneva, Switzerland, involving extensions, elevations, construction and the demolition of existing buildings. The contract is worth CHF 117.9 million (€108 million*).

The programme will create a sustainable neighbourhood with an intergenerational and social mix, able to accommodate 600 new residents. It will create 216 low-cost housing units, a 99-roomapartment-hotel, a medical centre and retail units, and will include the expansion of a 57-place day care centre. Similarly, an underground car park with 195 spaces will be built, allowing the creation of additional green spaces and meeting areas at ground level.

The project, known as "Côté Parc", aims to open up the Petit- Saconnex retirement home by integrating it fully into the life of the neighbourhood. It will ensure the institution's sustainability thanks to the annual rent to be paid by the investor to the retirement home in the form of a right of acreage agreement. This will allow the renovation of the existing buildings to be financed, as well as the development of new services for residents, employees and future inhabitants. In terms of the environment, this project is characterised by the creation of a five-hectare-plus park, unusual in the centre of Geneva, which will incorporate a wellness trail, vegetable gardens and an orchard, with new urban furniture

development. The new homes will also comply with the High Energy Performance (HPE) construction standards and the Swiss Minergie P energy label for buildings with very low energy consumption.

Works are scheduled to begin in autumn 2021, and the first homes will be delivered as of late 2023.

The Petit-Saconnex retirement home and Losinger Marazzi are partners in the project led by La Foncière, one of the largest real estate investment funds in Switzerland.
