The Principals of ARI entered North America in the early 1970s, holding an initial office in Toronto, Canada. Later, the Group opened its first U.S. office in Houston, Texas in 1977.
By the mid-1980s, the value of North American investments had grown to over two-billion dollars through real estate investments in major cities throughout the United States and Canada.
At this time, the majority of the holdings were sold in one large transaction to a Canadian public company. The Group's remaining assets were concentrated towards larger office buildings in
the United States.
