Dorchester based coffee shop chain Flat Black Coffee announced through their Twitter account Wednesday that their retail space by Peabody Square, currently housed inside Eastern Bank, has closed and moved to their Lower Mills location at 1170 Washington St.

Co-founder Jennifer House confirmed the move in an email to the Reporter, explaining that the company's lease at the Ashmont location had expired.

"The construction of the last two years, the parking being reduced and another coffee kiosk opening in the train station have had a negative impact on our business," House wrote. "We live near Ashmont and really love our community. The decision to permanently move our retail operation from Ashmont to Lower Mills was not easy. We roast all our coffees, daily, in Lower Mills. We hope to maintain the loyal customers we have been serving for over 10 years."

In addition to their Lower Mills location, Flat Black Coffee currently operates three locations in Boston's Financial District. The Washington Street location is open seven days a week.
