Burt Hill Architects was an American architectural firm active, under several names, in Butler and Pittsburgh, Pennsylvania, and elsewhere from 1968 until its 2010 acquisition by Stantec.

History and principals
Burt Hill Architects was founded in 1968 in Butler, Pennsylvania, as a successor to the practice of G. Edwin Howard, a regionally prominent architect. Architects Ralph H. Burt Jr. (1923–2005) and Alva L. Hill Jr. (1920–2015) were both natives of Pennsylvania and attended the Carnegie Institute of Technology in Pittsburgh with the class of 1952 before joining Howard & Murphy in Butler. In 1958 they became partners in the reorganized Howard, Burt & Hill. In 1966 the firm was incorporated, and in 1968 Howard retired. Burt and Hill continued the firm as Burt, Hill & Associates. Under Burt and Hill's leadership the firm rapidly expanded, opening offices in Pittsburgh in 1971 and Fort Myers, Florida, in 1973. In 1978 it was reorganized as Burt Hill Kosar Rittelmann Associates to reflect the admission of John E. Kosar and E. Richard Rittelmann (1938–2015) to the partnership.

In the 1970s the office became noted for solar design under the leadership of Burt and his associate, Rittelman. Their first major project in this area was the retrofitting of the 1962–built George A. Towns Elementary School in Atlanta with a solar heating and cooling system in association with the Westinghouse Electric Corporation in 1975. This has been removed but in its time was the largest such installation in the United States. Another large solar project was Comstock Center in Pittsburgh, completed in 1985.

Burt and Hill retired in 1989, but the firm continued to expand. By the early 1990s it had additional offices in Philadelphia, Washington, D.C., and Houston and was noted as the largest architectural firm in Western Pennsylvania. In 1998 it expanded internationally with an office in Dubai, and in 2005 was renamed a final time to Burt Hill Architects. The firm invested heavily in its international practice, and faltered after the 2007–2008 financial crisis led to the suspension of many proposed projects in the Persian Gulf. In 2010 it was acquired by Edmonton–based Stantec, which still (2023) maintains offices in Butler and Pittsburgh and a large practice in Western Pennsylvania.
