GREENWICH — A Chicago-based real estate company has purchased two prominent office buildings in downtown Greenwich.

Real estate watchers say the recent sale of 1 Lafayette Place and 1 East Putnam Ave. in Bradford Allen Investment Advisors highlights the attractive market conditions for offices in central Greenwich.

Terms of the sale were not made public. A real estate search firm, Green Street Real Estate Alert, said the properties sold for $78 million. Paperwork for the sale had not yet been filed with Greenwich Town Hall this week.

CBRE (Coldwell Banker Richard Ellis) negotiated the transaction.

“This transaction demonstrates Greenwich as an extremely desirable business destination for discerning businesses, which continue to demand high quality office space in a tight market in terms of locations and development,” said Steven Bardsley, executive at CBRE.

Jeffrey Dunne, another CBRE executive, said the Greenwich central business district is “the strongest CBD market in the United States.”

The firm noted that the office vacancy rate in central Greenwich is just 5.7%, with rents rising to over $100 per square foot at many properties. The two office buildings in question, totaling 90,268 square feet, are 100% leased.

The Greenwich central business district again had the lowest availability rate in Fairfield County, at just under 6%, according to a recent CBRE survey. The availability rate for the Greenwich market outside the central business district was 23%.

Wells Fargo and BlackRock are two of the largest tenants in the office complex.

The semi-detached properties were last acquired in 2019 for $57.5 million.

Bradford Allen Investment Advisors is the direct acquisition arm of Bradford Allen, a Chicago-based real estate services firm. This is the company’s first entry into the Connecticut market.

Messages left with Bradford Allen were not returned.

The seller was a joint venture between Dallas-based Lincoln Property Co. and Geneva-based Global Gate Capital.

The recent sale, while substantial, falls short of the year’s largest commercial real estate transaction, the sale of 100 W. Putnam Ave. by Apollo Global Management for approximately $200 million in March.
