ADP is proud of the significant projects undertaken by the firm since its founding. These include the restoration of the Church of St. Ignatius Loyola; the ongoing restoration work at St. Bartholomew's Episcopal Church; multiple restoration projects at Old St. Patrick's Cathedral; the LEED Platinum certified retail pavilion on Liberty Island; multiple and ongoing projects at the New York Marriott Marquis Times Square; long standing work at the historic Sherry-Netherland Hotel and Metropolitan Club; and the historic rehabilitation of the Ryan Visitor Center at Floyd Bennett Field. New York City's original Apple store and the Museum of Modern Art (MoMA) are just two of the major land-use planning projects in which ADP has had a defining role. Residential projects have also always made up a substantial portion of the firm's portfolio—from overseeing the $75M renovation of an Upper East Side condominium, to townhouse renovations and the design of new single-family homes.
