Erwin Walter Graebner
founding shareholder

Erwin Walter Graebner, born in 1939, is one of the most distinctive entrepreneurial figures in Germany’s real estate industry. During his career he brought up important innovations both in the field of tax-privileged investments and private property ownership. One of them is the development of the so-called "Bauherrenmodell”.

Being responsible as a developer and financial adviser for approximately 25,000 housing units, 20 hotels and being a long term part owner of LTU Group, the third largest conglomerate in the German tourism industry, his experience and advice is requested by banks, co-developers and private universities.

Since 1990 Erwin Walter Graebner addressed himself to the restoration of listed buildings – a subject for which he received an appointment as a lecturer at the European Business School (EBS) International University Schloß Reichartshausen.
