Bryant Bannister Tree-Ring Building

The Laboratory of Tree-Ring Research had been in temporary accommodation under the west side of the Arizona Stadium for over 70 years, but has finally moved into a permanent home, the Bryant Bannister Tree-Ring Building. The building is named for a former director of the Lab, who (although retired) still manages to contribute to dendrochronological research. It has been made possible by a donation from Agnese Haury, widow of noted anthropologist Emil Haury, and already the donor of several generous gifts to the University of Arizona, including a training fellowship offered through the Tree-Ring Lab. A groundbreaking ceremony for the new building took place on May third, 2011, and preparations for the construction began in November; people and equipment moved in on January of 2013, and the building dedication was on March 1. The first phase of the building is a completely new structure adjacent to the present Math East building (where the Tree-Ring Lab had already occupied some space in the basement). A subsequent phase will move storage of the extensive collection of wood samples into the Math East building, once its present occupants can be accommodated elsewhere.

The architect has taken an innovative approach to accommodating extensive laboratory and office space on a small area of ground, while maintaining some visual associations to tree rings. The building itself is almost literally a tree house, with a block of offices and laboratories suspended high in the air at the roof level of the present Math East building, and screened by individually articulated metal tubes that resemble the leaves of the palo verde tree. The main trunk beneath this block contains public exhibition space and the multipurpose room that serves as both auditorium and teaching lab. The other supporting columns branch into diagonal supports in a way that evokes additional tree trunks.
