Lift refurbishment with a focus on comfort and safety
KONE has replaced a total of 46 outdated lifts for 466 occupied flats in the Im Tiergarten housing estate in Zurich. The 18-month project, which was completed at the beginning of June 2025, is one of KONE's largest lift modernisation projects in Europe to date.
KONE has replaced the outdated lifts of a competitor in the Im Tiergarten neighbourhood of Zurich for 466 occupied rental flats. Within 18 months, the lift manufacturer from Brüttisellen installed a total of 46 of its MonoSpace 500DX lifts in one of Zurich’s largest residential complexes.
According to a company statement, this model adapts flexibly and with millimetre precision to the existing shaft. The payload of most of the passenger lifts has been increased from 320 to 480 kilograms. The new cabins are also significantly larger. According to KONE, they are monitored around the clock via the company’s digital asset management system and serviced proactively. This should lead to around 30 per cent fewer breakdowns.
The owners had decided to forego vacancy notices and to carry out further refurbishment measures while the building was occupied. According to KONE, it was able to adhere to the tight schedule thanks to a special logistics concept with overnight delivery and close coordination with the owners and residents.
The successful complete replacement in the Im Tiergarten development is one of KONE’s largest lift modernisation projects in Europe to date. According to Christian Herbst, KONES Director of Modernisation for Germany, Austria and Switzerland, “it shows that we are well positioned to meet an increasingly important demand in the market: the efficient modernisation of even a large number of installations, in close coordination with partners and under difficult conditions such as renovating while the building is occupied”.
