In 1995, city authorities offered the "Lower Manhattan Revitalization Plan" which offered incentives to convert commercial properties to residential use. According to one description in 1996, "The area dies at night ... It needs a neighborhood, a community." During the past two decades there has been a shift towards greater residential living areas in the Financial District, with incentives from city authorities in some instances. Many empty office buildings have been converted to lofts and apartments; for example, the Liberty Tower, the office building of oil magnate Harry Sinclair, was converted to a co-op in 1979. In 1996, a fifth of buildings and warehouses were empty, and many were converted to living areas. Some conversions met with problems, such as aging gargoyles on building exteriors having to be expensively restored to meet with current building codes. Residents in the area have sought to have a supermarket, a movie theater, a pharmacy, more schools, and a "good diner". The discount retailer named "Job Lot" used to be located at the World Trade Center but moved to Church Street; merchants bought extra unsold items at steep prices and sold them as a discount to consumers, and shoppers included "thrifty homemakers and browsing retirees" who "rubbed elbows with City Hall workers and Wall Street executives"; but the firm went bust in 1993.
