technologies to restore the historic fabric of the building and re-use historic materials." Prior to the building's closure in January 2000, a decision was reached to allot about one-third of the building's total space to the National Portrait Gallery while simultaneously eliminating the informal north-south division between the NPG and American Art Museum. This led to acrimony between the two museums, and a public debate about which collection deserved more space. The Smithsonian resolved the dispute practically: Art that best fit an exhibition space got it. (For example, since modern art often tends toward large canvases, this art is on the high-ceilinged third floor.) By March 2001, the cost of the Old Patent Office renovation rose to $180 million. That month, Nan Tucker McEvoy (a California newspaper heiress and arts patron) donated $10 million for the renovation. The Henry Luce Foundation gave another $10 million later that year. Costs continued to rise, however. Although Congress appropriated $33.5 million for the renovation, the reconstruction costs were estimated at $214 million in June 2001 and the museum not scheduled to reopen until 2005. Just a month later, the reopening was pushed back even further to July 2006. In 2003, the government's contribution to the renovation rose to $166 million, and more than $40 million in private funds had been raised. Smithsonian officials subsequently began discussing a major change to the renovation design: Adding a glass roof to the open courtyard in the center of the Old Patent Office Building. Congress approved the change in August 2003. In March 2004, the Smithsonian announced that Foster and Partners, would design the glass canopy. In November, Robert Kogod (a real estate development executive) and his wife, Arlene (heir to Charles E. Smith Construction fortune) donated $25 million to complete the canopy. By then, costs had risen to $298 million with $60 million in private funds still to be raised. In early November 2004, the National Capital Planning Commission (NCPC; which has statutory authority to approve all buildings and renovations in the D.C. metropolitan area) approved the preliminary design for the glass canopy. The United States Commission of Fine Arts, an advisory commission on design, approved the canopy in January 2005. Delays in obtaining final NCPC approval and construction materials for the canopy led to a major delay in the roof's installation. The Smithsonian said in April 2005 that the canopy would not be ready by
