Related to the transaction, Colonnade Properties and HCI agreed to apply this joint-venture structure when they acquire other class A properties in the US. "We are extremely pleased to establish this relationship with HCI as it provides us dedicated capital sufficient to purchase over $1 billion of stabilized office buildings within the next 18 months," Joseph Sambuco, president and CEO of New York-based Colonnade Properties LLC, says in a statement.

According to Oliver Georg, managing director of HCI Consult GmbH, the two plan to "establish a substantial presence within major US real estate markets in the near term."

Colonnade Properties owns, manages, leases, develops and redevelops office buildings across the country. The company has a $2-billion-plus portfolio of more than 30 properties with 11 million sf of commercial space. HCI, established in 1985, provides high-yield, tax-beneficial investments to private German investors, focusing on cargo shipping, private equity, life settlements and real estate.
