A 50 percent joint venture interest in 191 Post Road West, a brick, two-story Class A office building, was recently sold for an undisclosed amount by an affiliate of Westport's Paragon Realty Group to an affiliate of Investment Capital Partners of Fairfield.

The 32,000-square-foot building on Westport's west side is fully occupied, according to a news release.

Matthew F. Keefe, president of HK Group, a Westport commercial real estate firm, was the transaction's sole broker.
