Espace Tourbillon

Swiss Prime Site Immobilien’s largest real estate development project at present – ESPACE TOURBILLON – is characterised by five above-ground building structures that are to be constructed on a common, three-floor subterranean level. The flexible commercial buildings featuring a subterranean logistics infrastructure for trucks are oriented toward the needs of industrial, trade and retail tenants. The upper floor is ideally suitable for high-tech firms, biotechnology and clean-tech companies, as well as for R&D and commercial, retail or office use. The usable area amounts to 95 000 square metres. Two buildings were sold to the Hans Wilsdorf Foundation. Swiss Prime Site Immobilien will transfer ownership of the buildings to the Foundation in fully developed and turnkey condition. The buyer will provide the floor space to the canton of Geneva for important social institutions. One building is sold in condominium ownership. The ESPACE TOURBILLON major development project enables Swiss Prime Site Immobilien to provide the rapidly growing Geneva region with space for an additional 4 000 workplaces. The completion is scheduled for 2021.
