The Boston Globe reports that Leggat McCall Properties filed plans with the BRA to build about 700 apartments on Albany Street, a project that would be the biggest in a wave of development transforming a neighborhood that serves as the southern approach to downtown.

The proposal includes two buildings ranging up to 19 stories, would include mostly studios and one-bedrooms with street-level stores and a park between Harrison Avenue and Albany Street. One-fifth of the units will be set at rents affordable to low- and middle-income tenants.

A few blocks up Harrison Avenue from Leggat’s project site are the recently opened Ink Block, with 315 units spread across three buildings, and the Troy, a 19-story complex with 378 apartments. There’s a 160-unit building under construction at 600 Harrison, and site work has begun on a 602-unit complex farther north, near the Massachusetts Turnpike.

The developer Related Beal has an agreement to buy the site of Quinzani’s Bakery, a key parcel at the corner of Harrison Avenue and East Berkeley Street. The 5.6-acre site of the Boston Flower Exchange is reportedly near a sale for more than $40 million, although no buyer has been disclosed.
