The Patent Office Building in Washington, D.C., which has been closed to the public since 2000 for renovations, recently received a gift of $25 million from Robert and Arlene Kogod, Washington philanthropists and art collectors. According to an article in the Washington Post, the donation will be used toward a $38 million glass enclosure that will cover the building's courtyard.

British architect Norman Foster is designing the glass enclosure for what will be named the Robert and Arlene Kogod Courtyard. The courtyard will comprise 28,000 square feet.

The cost for the Smithsonian Institute to renovate the building and reinstall the museum is $298 million. It has received $166 million from the federal government and $70 million from the private sector, but still needs to raise $60 million more.

Renovation is expected to be complete July 4, 2006.
