Developer Robert Korff’s newest plans to remake Newton’s Washington Street corridor include a $139 million apartment complex called Dunstan East on 11 parcels including the Barn shoe store property.

Korff’s Wellesley-based Mark Development is seeking approval under the Chapter 40B affordable housing law for the 243-unit project, including 61 affordable units.

The Elkus Manfredi Architects designs call for three buildings on the 3-acre site comprising 11 parcels on Washington Street, Dunstan Street and Kempton Place, according to an application submitted to MassHousing. The site includes a mix of properties that Mark Development owns and others that it has an option to buy.

Mark Development acquired 32 and 32 Dunstan St. from In God We Trust RT in January for $4 million. The application estimates $25.3 million in total acquisition costs.

The shoe store which has operated since 1948 at the West Newton property has been offered space in Mark Development’s Washington Place, a store spokeswoman told The Boston Globe.

Newton officials have been studying rezoning for the Washington Street corridor but not taken any action yet. In a statement, Mark Development said it’s moving forward with the Chapter 40B process because the city has not taken any action its “Hello Washington Street” planning study, which launched in May 2018 and contemplated rezoning the corridor. The recommendations are under review by the city council.

“Unfortunately, neither the Vision Plan nor the accompanying zoning proposals have been adopted by the City Council as yet,” the company stated. “Therefore, we have decided to move forward with the project as a 40B proposal. We have heard repeatedly how important affordable housing is to our community. A 40B project at this site allows us to maximize affordability – offering 61 permanently affordable units. At the same time, we are confident that we are putting forward a proposal which overall is consistent with future zoning for this site, and a design that the city can embrace.”

Korff’s Mark Development is transforming a key intersection in Newtonville with the Washington Place project, which will include 140 housing units and nearly 44,000 square feet of retail space at Washington and Walnut streets. It’s also proposing a large mixed-use development including office space, a hotel and 675 residential units at the MBTA’s Riverside station and the Hotel Indigo properties on Grove Street.
