It’s no secret that Kendall Square is packed so tight with life sciences that firms are getting squeezed out and landing in Alewife, Somerville and Boston’s Seaport. Now a second mainstay of Cambridge biotech in a week has revealed it has its eye on Burlington, a town of some 26,377 people about 15 miles to the northwest.

The remaking of Harvard Square’s Garage mall has been revised to include lab and life-sciences space but less overall square footage; there’s an innovation in the signed community benefits agreement at Somerville’s Boynton Yards; and Harvard has photos of its renovated divinity school.

With a giant housing project in the works that will need money from the city’s Affordable Housing Trust, the Winn company had a response ready Thursday for an “unusual” letter of criticism filed by the mayor and vice mayor with the Trust’s board.

It wouldn’t feel right to let a week pass without another multimillion-dollar purchase by Denver-based Healthpeak in the Alewife area – and on Thursday came news of a $72 million transaction for 67 Smith Place.

Before a tree-cutting moratorium went into place in 2019, the pace of felled trees seemed to accelerate; while it’s not so simple for multimillion-dollar construction, developers, city councillors and Planning Board members are all trying to figure out how a lab- and office-space moratorium affects business as usual.

Rents were down 1.8 percent in December after a year in which Cambridge saw a 25.2 percent rise in prices and Somerville rose even more, according to some real estate industry analysts. Another local trend continued too: Life-sciences clusters spreading from Kendall Square.

An affordable-housing project that will overlook Danehy Park won praise from members of the Planning Board on Tuesday. One member called it a “poster child” for new Affordable Housing Overlay zoning that reduces the power of the board in refining projects before they’re built.

If the goal of eliminating single-family zoning in Cambridge is to right decades of racial injustice and inequity, the Planning Board was unconvinced Tuesday that the city was anywhere close to a way to achieve that.

Planning officials voiced serious misgivings last week around the specifics of the Affordable Housing Overlay, which so far underlies three projects making their way through Cambridge’s permitting process. But they acknowledged that they were forced mainly to watch with concern.

The Denver company Healthpeak spent another $41 million on Alewife-area property on Nov. 27, adding 125 Fawcett St. to the $391 million portfolio it’s built since August, according to documents filed Tuesday with the Middlesex Registry of Deeds.
