From Boston to Los Angeles, from New York City to Chicago to Dallas, museums are either planning, building, or wrapping up wholesale expansion programs. These programs already have radically altered facades and floor plans or are expected to do so in the not-too-distant future.
In New York City alone, six major institutions have spread up and out into the air space and neighborhoods around them or are preparing to do so.The reasons for this confluence of activity are complex, but one factor is a consideration everywhere — space. With collections expanding, with the needs and functions of museums changing, empty space has become a very precious commodity.
Probably nowhere in the country is this more true than at the Philadelphia Museum of Art, which has needed additional space for decades and which received its last significant facelift ten years ago.
Because of the space crunch, the Art Museum has become increasingly cautious in considering acquisitions and donations of art, in some cases passing up opportunities to strengthen its collections.Deaccessing — or selling off — works of art has taken on new importance because of the museum’s space problems. And increasingly, curators have been forced to juggle gallery space, rotating one masterpiece into public view while another is sent to storage.Despite the clear need for additional gallery and storage space, however, “the museum has no plan, no plan to break out of its envelope in the next fifteen years,” according to Philadelphia Museum of Art’s president.
从波士顿到洛杉机，从纽约到芝加哥、到达拉斯，所有的博物馆或者正在筹划、建造或者正在完成大规模的扩建计划。 这些计划或者已经根本性地改变了博物馆门面与展厅的设 计，或者预期在不久的将来会这样做。
单单在纽约市，六个主要机构或者已经向空中和周 围扩展，或者正准备这样做。大家一致行动的原因是复杂多样的，但其中的一个因素是普遍 考虑的空间问题。
