Preparation Brown's "Policy Statement" set a clear architectural direction by calling for the new building to be "a work of art", It was augmented by his "Pre-Architectural Program", which specified that "natural light should play a vital part" in the design and that "the form of the building should be so complete in its beauty that additions would spoil that form." Brown called for a building of modest scale that would not overwhelm either the artwork or the viewer. The new museum was to be built on a gentle slope below the
Amon Carter Museum, whose entrance and terrace faced the Fort Worth skyline. Kahn was asked to build the Kimbell museum no more than 40 feet (12 m) high so it would not interfere with the view from the Carter Museum. Kahn initially proposed a low but very spacious building 450 feet (137 m) square, but Brown rejected that proposal and insisted that Kahn design a much smaller structure, a decision that would have repercussions several years later when a proposal to expand the building created a storm of controversy.
Architecture The museum is composed of 16 parallel vaults that are each 100 feet (30.6 m) long, 20 feet (6 m) high and 20 feet (6 m) wide (internal measurements). Approaching the main entrance past a lawn edged by pools with running water, the visitor enters a courtyard through a grove of Yaupon Holly trees. The sound of footsteps on the gravel walkway echoes from the walls on either side of the courtyard and is magnified under the curved ceiling of the entry porch. After that subtle preparation, the visitor enters the hushed museum with silvery light spread across its ceiling. Kahn was pleased with this development because it allowed him to design the museum with galleries that resembled the ancient Roman vaults he had always admired. The thin, curved shells needed for the roof were challenging to build, however, so Kahn called in a leading authority on concrete construction,
August Komendant, with whom he had worked before (and who, like Kahn, was born in
Estonia Both terms, vault and shell, are used in professional literature describing the museum. True
vaults, such as the Roman vaults that Kahn admired, will collapse if not supported along the entire lengths of each side. Not fully understanding the capabilities of modern
concrete shells, Kahn initially planned to include many more support columns than were necessary for the gallery roofs. The long, straight channels at the bottoms of the shells were cast first so they could be used as platforms to support the workmen pouring concrete for the
cycloid curves. After all the concrete had been poured and strengthened with internal
post-tensioning cables, however, the curved parts of the shells carried the weight of their lower straight edges instead of the other way around. Esther Kahn, Louis Kahn's widow, published a letter voicing similar sentiments, noting that "there is room on the site for a separate building, which could be connected to the present museum." The project was cancelled a few months later.
Renzo Piano Pavilion In 2006, the idea of an expansion surfaced once again at a dinner in Fort Worth attended by Timothy Potts, the museum's director at the time (Eric M. Lee has been the director since March 2009); Kay Fortson, president of the Kimbell Art Foundation and a key figure in the creation of the original building; Ben Fortson, a trustee; and Sue Ann Kahn, Louis Kahn's daughter and a vocal opponent of the original plan for expansion. The new proposal was exactly in line with Louis Kahn's own thoughts for expansion: a separate building. The schematic designs for the new Kimbell building were made public in November 2008, and the plans were released in May 2010. The 85,000 square foot (7,900 m2) structure would complement the original building but not mimic it. Unlike the original, its lines would be rectilinear, not curvilinear. Like the original, however, it would have three bays with the middle bay stepped back from the other two. The new building expansion, named the Renzo Piano Pavilion, was officially inaugurated to the public on November 27, 2013. The new building should also resolve a parking issue at the museum. Kahn was deeply troubled by the negative impact of the automobile on city life; he once spoke of "the destruction of the city by the motor car." Fundamentally opposed to the idea of orienting buildings to the automobile, Kahn placed the main parking lot in the back of the building, intending for visitors to walk around the building and enter through carefully planned landscaping. Most visitors, however, entered through the back door on the ground floor, missing the entry experience that Kahn had designed. • Robert McCarter, author of
Louis I. Kahn, said that the Kimbell Art Museum "is rightly considered Kahn's greatest built work" and "has been the subject of more scholarly studies than all his other works combined." ==European collection highlights==
