Montclair, N.J. — The Hampshire Cos., along with joint venture partner Pinnacle Cos., have announced plans to redevelop Lackawanna Plaza in Montclair. The planned 216,772-square-foot mixed-use redevelopment is expected to revitalize the complex through the development of a range of modern retail, office and residential spaces while preserving historical elements of the station. Originally built in 1913, Lackawanna Plaza was a stop on the Delaware, Lackawanna and Western Railroad until the station’s closure in 1981. The site will be anchored by a 28,509-square-foot Lidl grocery store. In addition to Lidl, plans call for 35,714 square feet of retail space and 21,032 square feet of office space. A 153-unit mixed-use residential building is also planned for the eastern side of the site along Grove Street. Construction is expected to begin later this year.
