HARTFORD — A crucial component of an ambitious, $100 million redevelopment of downtown Hartford’s Pratt Street corridor — the conversion of student housing behind the Lofts at Main and Temple into apartments — could begin in November, even as the duration of the global pandemic remains uncertain. “Yeah, we got punched in the nose with the pandemic just like everyone else,” Martin J. Kenny, president of Hartford-based Lexington Partners, said. “But I think we are going to recover, and certainly we’re all seeing some bounce in terms of housing in Connecticut. I think this is going to be a great alternative. “The $9.1 million conversion also includes improvements and upgrades to the adjoining Lofts at Main and Temple apartments, fronting on Main Street and incorporating the facade of the old Sage-Allen & Co. department store.
