A Pittsburgh-based construction company has been given approval to build a 225-unit apartment complex on the southern edge of town. Despite opposition from some residents, the Newington Town Plan and Zoning Commission voted earlier this month to approve a proposal to construct five four-story residential buildings on a 26-acre site at the corner of Culver and Deming streets. The A.R. Building Company, which owns and manages more than 9,000 units of housing across the country, proposed the development at 258 Deming St., and 35, 67 and 69 Culver St. William Sweeney, an attorney representing the developers, said the company will also manage the property and staff the on-site leasing office when construction wraps up. Once completed, the property will be accessible from two entrances on Culver Street. The complex’s parking lot will feature more than 370 spaces, up to 40 percent of which will feature charging stations for electric vehicles.
