Real Estate

Over the past decades, Diethelm Keller Group has built up a significant real estate portfolio. This independently run entity is part of the Group’s asset class. Traditionally, these properties are occupied by the Group’s operational units or let out to third parties. Changing global market conditions are continually analysed and turned into actionable projects.



    The Headquarter of the Diethelm Keller Group is located in the city center of Zurich in the very upscale Seefeld district close to the railway station and with easy access to the airport. The building is overlooking the city with views over the lake and mountains. The top floors are occupied by Diethelm Keller, the remaining floors rented out.

    Eggbuehl - Zürich

    Following the strategic decision in 2015 to transform and develop the Eggbuehl site into a mainly residential property for the rental market, implementation is well on track. Construction at Eggbuehl, previously used for commercial purposes, began in early 2018 with the dismantling of existing structures and major groundwork. The construction of the energy-efficient double brick work is completed and the interior fittings are progressing well. The first Apartmens will be ready for occupancy in spring 2021.
