This house is one of seven ­structures on Alexander Street south of University Place that the ­University is offering free to ­people who will pay to move them elsewhere. The buildings must be moved by April 30, or they will be demolished to make way for Princeton’s arts and transit ­project. The houses are “not in move-in condition,” the University said. For more information, ­contact the Office of Community and Regional Affairs (pucra@princeton.edu).
