Allston Yards’ developers are accelerating plans for condominium construction after reaching agreement with the owners of a neighboring property, bringing the project’s housing component to more than 1,000 units.

The vacant property at 52 Everett St. will be replaced with a 150,000-square-foot condo building, including income restrictions for 16 percent of the 150 units, according to a project change submitted to the Boston Planning & Development Agency.

New England Development is partnering with Stop & Shop Supermarket Co., Southside Investment Partners and the Bozzuto Group on the 1.2 million-square-foot redevelopment of the grocery-anchored shopping center bordering the Massachusetts Turnpike.

Approved in 2019, the development originally called for 758 apartments and 110 condos, along with a 373,500-square-foot office-lab building. Construction of the first phase, including 156 housing units and redesign of the existing supermarket, began last fall.

Developers recently reached agreement with 52 Everett St. owner WJG Realty Company LLC to add the parcel to the master-planned project, New England Development Executive Vice President John Twohig wrote.

The 60,000-square-foot grocery store, which was built in 1998, is being expanded to 87,200 square feet.

A BPDA comment period on the proposed changes runs through April 13.
