Joseph Coppola, of Dattner Architects, discusses the renovation of Wave Hill, which was built in 1843 by William Lewis Morris. Famous residents include Theodore Roosevelt, Mark Twain and Arturo Toscanini. The estate was deeded to the City of New York in 1960 and Wave Hill, Inc., was formed in 1965 as a non-profit corporation. Wave Hill House is on the National Register of Historic Places. Dattner Architects was retained by Wave Hill to update their Master Plan and to design renovations to the House, funded through the NYC Department of Design and Construction. Designs were approved by the New York City Landmark Commission.
