One of Germany’s Leading
Residential Property Specialists

The d.i.i. Group was formed in 2006 as an integrated residential property company with outstanding expertise in portfolio development and the new-build construction of residential real estate


  • Setting up and managing residential property portfolios for private, semi-professional and professional investors, as well as for its own portfolio, constitutes the core business of the d.i.i. Group.
  • As leading specialist for residential real estate, d.i.i. provides its entire range of deliverables as in-house services – from property acquisitions, to funding, asset development and asset management,
    and all the way to the property disposal.


The company prefers to acquire residential real estate with high capital appreciation potential in Class B cities and in selected micro-environments of Germany’s metropolises. By now, the d.i.i. Group has invested in more than 50 locations, while its assets under management add up to a current total value of c. 4.0 billion euros.

The company’s proprietary construction, project and asset management business employs the relevant value-add levers to carry out comprehensive refurbishment and/or construction measures, e.g. through infill densification. Upon completion of these, the flats are either retained in our proprietary portfolio or sold as condominiums to tenants, owner-occupiers and private or buy-to-let investors.

The d.i.i. Group employs a total of 280 staff at its head office in Wiesbaden and in branch offices on the ground in the metropolises we do business in.
