Fund/portfolio management through proprietary AIFM in Germany and Luxembourg
We conceptualise and establish investment vehicles to meet the needs of domestic and foreign investors. We actively manage them from Germany and Luxembourg in a performance-driven way in line with investment objectives and in close cooperation with our clients.

Investment at home and abroad
We see ourselves as a legitimate representative of the owner: We find the "right assets" and structure the entire purchasing process for our clients – from sourcing the property, performing the due diligence and purchasing contract negotiations to taking over the asset management.

Asset management
We mobilise the potential of our assets under management for investors, financing banks and companies with their own real estate. We offer them services encompassing the full real estate lifecycle: from analysis and evaluation, including property management and development to marketing. Our clients enjoy a customised service for the following asset classes: office, retail, health care, logistics & light industrial and residential.

Commercial and residential project development
In addition to selected commercial projects in Germany, we realised over 300 residential units with a marketing volume of over EUR 170 million in 2020. We manage the full implementation – including project planning, construction and sale to private or institutional investors.
