Macklowe Properties was founded in the mid-1960's by Harry Macklowe. For over 40 years, the company has been an active developer, acquirer, redeveloper, owner, and manager of a diverse array of real estate investments. The company has successfully achieved a full level of vertical integration, combining design, planning, construction, management, accounting, and executive-level ownership and operation to provide for absolute responsibility and control over its assets. These investments, which have covered virtually every sector of the property market, have included the development, acquisition, and repositioning of office and apartment buildings, land assemblages, and conversion of industrial and loft properties. In the aggregate, these developments have totaled over 10 million square feet and have taken place in nearly every commercial and residential submarket of Manhattan.
