Summary
Eiffage Immobilier and Alterimo, which describes itself as a benchmark player in the senior living sector, have announced the signing of a partnership to develop and operate a new concept of serviced senior residences in Switzerland. The partnership will be implemented through a 50/50 joint venture that will oversee the new offering. Eiffage contributes real estate development and construction expertise in Switzerland, while Alterimo brings operational capabilities drawn from its portfolio of more than 1,200 housing units in French-speaking Switzerland.
The partners cite strong structural demand in the Swiss market. According to the announcement, Switzerland will have 2.38 million people aged 65 and over by 2040, a 30% increase from today, alongside growing demand for adapted housing and a shortage of places in specialized care facilities. In the short term the partners aim to establish at least five residences, with a view to expanding to ten, in prime locations within major urban areas across both French-speaking and German-speaking Switzerland.
The concept draws on the Cazam serviced senior residences developed by Eiffage Immobilier in France. The companies position the offering as an alternative between traditional housing and medico-social institutions. Each premium residence is planned to include around one hundred apartments ranging from 1.5 to 3.5 rooms, along with shared facilities such as a restaurant, bar, fitness room, cinema, wellness area and a comprehensive service hub.
Sébastien Argoullon, Real Estate Director of Eiffage in Switzerland, said the partnership allows Eiffage to position itself as a major developer in Switzerland in the high-growth serviced senior residence segment, describing the projects as high-quality, sustainable living spaces tailored to seniors. Dominique Diesbach Vernevaut, Managing Director of Alterimo, said the model meets the evolving expectations of Swiss seniors and that the partnership opens German-speaking Switzerland to Alterimo, a key milestone in its geographic expansion. The announcement did not disclose investment amounts or project timelines beyond the short-term target.
