San Diego Mesa College is one of the largest community colleges in California. Each semester, the college serves over 30,000 students. The campus has undergone major improvements since 2006 including 3 new state-of-the-art buildings. The Center for Business & Technology is Mesa’s final classroom building project. Campus improvements were funded by the San Diego Community College District’s construction bond program. For more information on the program, visit San Diego’s Community College District website.


The new building is expected to receive LEED accreditation (Silver certification) for green building and design. The most notable features are not inside the building but out. Designed by San Diego’s McCullough Landscape Architecture, the exterior spaces maximize site functionality and sustainability.

The building was designed to form two branches, the middle of the branch opening to an exterior courtyard as an open-air classroom and gathering space. Large flat slabs of stone (Arizona Sandstone Bench Boulders) were arranged to be used for group seating.

Brittany Marcik, (outside sales – San Diego) worked with McCullough’s Shawna Bortolussi to choose the large flat slabs of stone. After visiting our Fallbrook branch, McCullough chose 11 Arizona Buff Sandstone Bench Boulders ranging in size from 3 ft. to 6 ft. The benches and surrounding materials were installed by Buenavista Landscaping.


The goal was to provide permanent, weatherproof seating. Not only that but the stone bench boulders also added height and depth to the otherwise flat area. Glacier Pebble and Supreme Walk On Bark Mulch surrounded the buff-colored benches. Adding rounded pebbles and bark mulch softened the otherwise strong edges of the natural stone slabs.

More show-stopping landscape designs can also be seen in the CBT courtyards. Rectangular paving stones in varying sizes surrounded by Polished Black Pebble. The light gray steppers “pop” due to the surrounding midnight black pebble. The entire landscape is absolutely beautiful.


The CBT offers texture, color, and contrast without forgetting function. We are fortunate to supply the landscaping materials used at Mesa College. Special thanks to McCullogh Landscape Architecture, Buenavista Landscaping, and everyone involved. Let us know what you think when visiting the campus!

About the Center for Business & Technology:

The new $32.2 million, 57,800 gross square feet Center for Business & Technology will serve as a home for Mesa’s business, computer, and fashion design programs.  The facility will include technology-rich classrooms, a case study-type classroom, computer laboratory classrooms, a fashion design laboratory, and faculty and staff space. The entry to the building will include a large video display wall.  The project will also include hardscape and landscape improvements.


In keeping with the district’s Green Building Policy for all Propositions S and N-funded projects, the Center for Business & Technology is expected to be awarded a Leadership in Energy and Environmental Design (LEED) Silver certification for green building and design – one of 42 LEED certifications across the District. It includes a number of sustainable features:


  • The building will have active/hybrid passive ventilation on the second-floor classrooms and faculty offices. The ventilation system uses a series of efficient rooftop air handling units with individual Variable Air Volume (VAV) systems in each room; each room has an operable opening of at least 5% of the floor area. Once a window is opened, the system is signaled to turn off heating/cooling and actively assist with pulling air through the space with the VAVs.
  • The building design maximizes the use of natural daylighting; commissioning collaboration from an early stage will continue to ensure optimal building efficiencies.
