There’s so much development in Cambridge that even watchdog Charles Teague can’t keep up. This year, in looking at potential zoning changes, he put together a comprehensive map showing some 1,400 units estimated to be on the way in addition to the 333 built in the area in the past five years.

Now, though, he knows it’s 1,410 units on the way, including these two Bay State Road buildings of five units each — apparently to be known as “Bay State Corner” — tucked away behind the Sozio Home Furnishings and Appliances showroom, across from the Fresh Pond Reservoir. The developer Abodez describes the project as two- and three-bedroom condominiums expected to be done this summer. The average listing price for Neighborhood Nine homes is $665,468, according to the Trulia real estate website.

“It is a lot of density going in at Fresh Pond,” Teague said Wednesday, noting that down the road is developer Peter Lee’s Bay State Flats, a 23-unit, multistory loft building put up in 2006 (with Lee calling it an “engineering marvel” to get underground parking in an area so wet it’s “like a boat”) — the same Lee set to replace Cambridge Lumber with 20 condominiums and whose site lists him working on a three-unit building at 477 Concord Ave. and in the design phase for a renovation of the Fresh Pond Mall.

What caught Teague’s eye at Bay State Corner, he said Tuesday, was how the apartments are being put together in modules, stacked via crane and finished on the ground.
