The Miller House and Garden, in Columbus, Ind., has been donated to the Indianapolis Museum of Art. Commissioned by J. Irwin Miller and his wife, Xenia Simons Miller, and completed in 1957, the home was designed by Eero Saarinen, with interiors by Alexander Girard and a landscape shaped by Daniel Urban Kiley. Members of the Miller family and the Irwin-Sweeney-Miller Foundation are pledging $5 million toward an $8 million endowment for the property; the museum is raising the other $3 million, as well as $2 million for a renovation of the house, expected to take 18 months. The Miller House and Garden was designated a national historic landmark in 2000.
