The milestones of our company history:
- In May 2023 Grossmann & Berger continues its expansion strategy by opening a new shop in Reinbek.
- To place ourselves in an even broader regional position, in 2021, we held a majority stake in the E & G companies in Stuttgart and Munich. Through these locations, we're now also represented in the two southern metropolitan regions with our residential and commercial divisions.
- In May 2020, Grossmann & Berger opened a property shop in the southwest of Hamburg in Buxtehude.
- In April 2019, our Norderstedt property shop opened its doors north of Hamburg.
- As part of the largest single property transaction in Hamburg at around €400 Million, in 2018, we acted as agents for the sale of buildings A and B in the "Springer-Quartier“ in Kaiser-Wilhelm-Straße. The seller was a joint venture between the MOMENI Group and Black Horse Investments, with the buyer being a company of professional pension funds.
