Lyndell’s, the iconic Ball Square bakery that holds the title of oldest scratch bakery in New England, is expected to stay in business (it makes a mean cupcake, among many other treats) as it gets a makeover. Somerville has approved a redevelopment that will, when finished, include a larger retail space for Lyndell’s and a four-story apartment building with 30 units.

The project is slated to begin within a year or two and take about a year, Lyndell’s owner Bill Galatis said. That means the new-and-improved Lyndell’s should be set to open sometime between early 2026 and 2027. It will be larger and offer seating indoors and – city permitting – outdoors.

“My objective is to create the traditional, classic bakery look,” said Galatis, who has been at the helm since 2000 and is only Lyndell’s fourth owner since it opened in 1887. “I want to incorporate the things we currently have and that customers enjoy.”

The DiCamillo Associates project will involve knocking down the existing Lyndell’s structure at 720 Broadway, which was built in 1900, as well as the three-family house next door.

“The landlord has always had an interest in redeveloping that corner, and I think it became heightened when the new Ball Square green line T stop opened,” Galatis said.

During the year of construction, Lyndell’s plans to stay open.

“We’ve been canvassing locations within a half-mile radius of our current location, and we’ve identified three or four potential spots that we think will work while the current building is being demolished and the current building is being built,” Galatis said.

He said he feels “pretty good” about their chances of finding a new retail space, citing a number of spaces that seem to meet their requirements for the temporary bakery.
