A spokesman for CB Richard Ellis, whose Long Island office arranged the lease, tells GlobeSt.com Berkman Henoch considered properties in the surrounding markets of eastern Nassau County before deciding to stay in place. "The right answer was to continue a positive, long-term relationship with the property," says CBRE's Philip Heilpern in a release. "It was a terrific business deal, one that met our client's objectives. Moreover, we were able to negotiate attractive economics that are in line with current market dynamics."

By remaining in its present location, the law firm was able to avoid the cost of relocating while performing interior improvements to accommodate personnel at the 100 Garden City space, the CBRE spokesman says. The same CBRE team--Heilpern, Richard Karson and Martin Lomazow--had arranged the lease when Berkman Henoch moved into the space in 1999. Treeline was represented in-house in negotiations.

The 131,000-square-foot 100 Garden City Plaza is one of three neighboring buildings originally built in 1969 and purchased by Treeline from Garden City Plaza Associates for $43.4 million in 2001. All told, 100, 200 and 300 Garden City Plaza, which Treeline renovated after buying them, contain more than 400,000 square feet of office space. A fourth building, the 180,000-square-foot 400 Garden City Plaza, was constructed in the late 1980s; Treeline bought that property from Reckson Associates for $30 million in 2004.
