Real Estate

Over the past decades, Diethelm Keller Group has built up a meaningful real estate portfolio. Properties are typically leased to third parties or used by the Group’s operating units. This independently run entity is an important asset class of the Group. Hence, changing global market conditions are continually analysed and opportunities turned into actionable projects when promising.



    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 energetic double-walled buildings were completed in the middle of 2021 and the tenants have moved into their apartments as well as the commercial areas.

It offers the oportunity to not only work inside historical buildings, but at the same time in modern office, business and commercial premises.
