GHP Office Realty acquired One Byram Brook Place, a two-story, 24,295-square-foot office building in Armonk, NY. Shortly after closing on the building, the White Plains, NY-based real estate firm put the property on the market for sale for $5 million. GHP Office Realty and a group of investors acquired the building from Byram Brook Estate LLC of Garden City, LI, for an undisclosed price. The acquisition of One Byram Brook Place marks GHP's third office building purchase so far this year. The company recently acquired 145 Huguenot St., a 300,000-square-foot office building in New Rochelle, NY, and 12 Water St., a 45,000-square-foot office building in White Plains, NY.
