A new proposal seeks to build a large, mixed-use development on Black Rock Turnpike, that would add thousands of feet of co-working space and nearly 250 apartments. Post Road Residential is asking the Town Plan and Zoning Commission to conduct a non-binding pre-review on its plans for a five story building with 243 residential units, a 10,000 square foot amenity space and a 6,000 square foot co-working space at 81 Black Rock Turnpike, also known as the Reiner Property. Chris Russo, the attorney for the developer, said the property is currently an eyesore and the proposal will completely turn that around. He said it has been designed in a way that is in line with the town’s transit oriented development study. Commission Chair Thomas Noonan asked if the developers were aware of the Fairfield Metro development breaking ground nearby, and if they plan to complement it. The developer’s team said they looked at those plans.
