University of California, Riverside campus

They were designed by Lester H. Hibbard of Los Angeles, a graduate of the University of California School of Architecture, in association with a colleague, H.B.

Built at a cost of $165,000, the architecture of the major buildings followed the Mission Revival style suggesting the Spanish colonial heritage of Southern California.

The 49,794 ft (15,177 m) Webber hall was designed by Chambers & Hibbard and cost $1,135,960, partially paid by State Fair and Exposition funds.

The 60,257 ft (18,366 m) Social Sciences Building, later renamed Watkins Hall, was designed by the firm of Clark & Frey and cost $1,051,000.

Past the freeway, over 500 acres (2.0 km2) of agricultural fields extended northwest to the intersection of Chicago Avenue and Le Conte Drive, forming the borders of "West Campus."

After the drop in enrollment and subsequent restructuring of academic programs in the 1970s, little capacity construction was undertaken over the next two decades, except as required by the developing research interests of CNAS.

Boyce Hall, completed in 1974, was the only major addition in the period, although several greenhouses and agricultural support units continued to be built.

The Campus Commons (Phase I), 'Glen Mor' Arroyo Student Housing Apartments, and Alumni & Visitors Center were recently completed.

The first phase of the new $50 million Commons was recently completed, and includes meeting rooms, dining areas, places to study, and office space for student programs.

Forming the southeastern border of the Riverside campus are the Botanic Gardens, which occupy 40 acres (160,000 m2) of rugged terrain in the Box Springs foothills.

University Extension, the USDA Germplasm Repository, International Village (student housing), a parking lot, office buildings (Human Resources and Highlander Hall), and other small no are also located on the West Campus.
