New home for senior citizens Greencity 2026
In autumn 2026, the sustainable Greencity district in Zurich South will be completed with the development on construction site B6. This innovative project, developed by Losinger Marazzi AG, comprises 179 age-appropriate flats and represents a significant step forward in urban housing design.
A visionary residential project is being built in the south of Zurich that offers older people a lively and safe environment. The development on construction site B6 in Greencity combines private and municipal involvement. Losinger Marazzi AG is developing the project for the investment foundations of Pensimo Management AG, which are providing a total of 179 flats for older people. Of these, the City of Zurich Retirement Homes Foundation (SAW) will take over 60 flats, while the remaining 119 flats will be let by Pensimo to tenants aged 55 and over. This collaboration represents a new partnership and gives all tenants access to SAW’s services.
A green centrepiece for Greencity
Construction site B6 is the latest chapter in the sustainable development of the Greencity district. Since 2014, Losinger Marazzi has been transforming the site of the former Sihl paper factory into Switzerland’s first 2000-watt site. The inner courtyard of the new building will feature green areas, trees and seating, inviting people to linger. Arcades on the ground floor create sheltered access areas to commercial spaces, which could offer facilities such as a medical centre, a fitness studio, a bakery or a café on 3,500 square metres, says René Büchi, the portfolio manager responsible at Pensimo.
Comprehensive services from SAW
The City of Zurich Retirement Homes Foundation provides all tenants with a comprehensive service package. This includes a 24-hour emergency call service, extended caretaking, laundry service, social services and various events on the estate. If required, tenants can also take advantage of home help and outpatient care services. Andrea Martin-Fischer, Director of SAW, emphasises: “Our aim is to enable tenants to live independently and safely well into old age.”
Focus on sustainability
Greencity’s sustainability goals are consistently applied to the new retirement housing project. Herbert Heinen, Project Manager at Losinger Marazzi, explains: “An optimised load-bearing structure, lightweight walls, a wooden façade and an energy concept with 100 percent renewable energy significantly reduce CO2 emissions and bring the building close to the net-zero target in operation.” Pensimo and Losinger Marazzi are also aiming for certification with the SNBS Gold label. Construction started in March 2024 and the building, designed by JSWD Architekten from Cologne, is scheduled for completion at the end of 2026.
With this pioneering project, Greencity is setting new standards for sustainable, age-appropriate living and demonstrating how private and public partnerships can create forward-looking solutions.
