28 Costello Place is a fully renovated (2026) industrial/flex building on 1.27 landscaped acres in an established industrial park just off the Berlin Turnpike in Newington. Originally built in 1987, the split-face concrete block building features a clear-span shop with 20' clear heights, four grade-level drive-in doors (three 12' x 14', one 14' x 14'), 400 amp / 3-phase / 208V power, gas heat, HVLS fans, and LED lighting, plus an air-conditioned mezzanine office suite served by a separate 100 amp panel. The site offers on-site parking, a fenced gravel yard for outdoor storage or fleet parking, and pole signage at the street. Centrally located in the Hartford market, minutes from I-84, I-91, Route 9, and Route 15 — ideal for contractors, light manufacturing, service businesses, and warehouse users.
