National Development of Newton yesterday told the BPDA it plans to file plans soon to replace a series of warehouses between F.W. Webb and Benjamin Moore on Dorchester Avenue, near Old Colony Avenue, with a four-building development - two buildings with 345 residential units and two buildings with 674,500 square feet of commercial space.
The company did not specify whether the "commercial" space would mean offices or, as has become popular among Boston developers these days, life-sciences laboratories.
National Development says it is also planning about 55,000 square feet of ground-floor retail space for the complex, along with an unspecified amount of parking.
323-265 Dorchester Ave. letter of intent.
