5 $100M-Plus Deals Quietly Closed Around Boston As 2020 Wrapped Up


Commercial real estate did not go silently into the night before the new year, with several nine-figure deals closing quietly in Boston’s suburbs.

Major transactions in every asset class posted in the days before the calendar flipped, a small flurry of deals before the year’s end representative of the unique pressure on buyers to get deals done before the end of Q4.

Here are the five largest deals around Boston that closed in the waning weeks of 2020, according to a Bisnow analysis of public land records.


152 Grove St., 43 Foundry Ave. and 41 Seyon St., Waltham

The office building at 43 Foundry Ave. in Waltham.

Buyer: TPG
Seller: Hilco Real Estate
Price: $344M

Hilco flipped a 615K SF campus 10 miles from Boston for a hefty price to holding companies tied to San Francisco-based private equity firm TPG.

The Illinois-based seller bought the two-building office campus at 43 Foundry Ave. and 41 Seyon St. known as CenterPoint from a Rubenstein Partners and Saracen Properties joint venture for $86M in 2018, Commercial Property Executive reported at the time. The site was a former research and development and manufacturing hub for Raytheon and was then occupied by life sciences and office tenants.

The $344M deal, which closed on Dec. 21, according to property records, also includes The Gauge. Hilco redeveloped the 135K SF former Standard Thomson Co. industrial headquarters into lab and office building, leased to Panasonic and Humatics, according to Colliers. The Gauge is fully leased after recently signing UK biopharmaceutical firm Abcam Inc. to a 100K SF lease, according to Newmark.

The 350K SF, two-building headquarters was purchased in separate deals totaling $252M Dec. 21 from Gutierrez, which has developed 2M SF of life sciences assets in Burlington alone.

MilliporeSigma has seen a boost in business during the coronavirus pandemic, developing supplies for labs working on COVID-19 vaccines, it said last month. Merck’s North American arm last month also is spending $47M to expand production facilities in Danvers and New Hampshire.
