Founded in 1949, Hanna Boys Center is situated on a 170-acre campus in rural Sonoma County. As one of the Northern California’s most successful residential treatment centers, Hanna provides 120 at-risk boys an opportunity to turn their lives around. Hanna offers a home and treatment services to boys 24 hours per day, 365 days per year, and educational services for grades 7-12.

The final draft of a 10-year campus Master Plan was completed by CSDA and approved by the Hanna Board of Trustees on December 8, 2008. The Master Plan detailed strategies for facility upgrades, complete renovations, new buildings, and recreational facilities required to meet the current and future needs of the campus.

Phase 1 of the Master Plan included the following major elements: upgrade main entry and entry road; new 7,800sf admission/alumni center; new 11,100sf multi-use auditorium; new multi-use artificial turf baseball field; and seismic upgrades for the chapel, gym, and wood shop. Phases 2 through 4 included complete renovation of the dining facility, a new learning center and added classrooms, main quad renovation and new amphitheater, two new group homes, parking, guest house, renovation and additions to the gymnasium, renovation of the multi-use field and residential cottages, and a new 4-H facility.


Established in 1951, Bishop O’Dowd High School is a recognized leader in college preparatory education. With a vision of maintaining this leadership into the 21st century, CSDA was selected to develop a comprehensive Master Plan with detailed strategies for future modernizations, complete renovations, new buildings, and recreational facilities.

CSDA developed the Master Plan to meet current and future needs of the school, with an existing enrollment capacity of 1,125 students. The plan had several phases and incorporated strategies to design/construct new facilities and modernize existing buildings over a period of 10-15 years.

The first phases were focused on the modernization of 28 classrooms and four science labs, the seismic retrofit of an existing gymnasium, and the addition of two environmental classroom labs. Future phases included a new athletic center, student center, cafeteria, chapel, counseling center and administration building and renovations/additions to existing buildings.



CSDA completed the initial implementation phase of the design, as outlined in the school’s comprehensive Master Plan, which included the modernization of 28 classrooms and four science labs, the addition of two environmental classroom labs and the seismic retrofit of a gymnasium. The modernized classrooms are energy-efficient and designed to be flexible and to accommodate various teaching styles. The upgrades include new teaching walls, LCD projectors, wireless/smart box technology, and moveable furniture.

Future phased construction will include a new athletic center, student center, cafeteria, chapel, counseling center and administration building, and renovations/additions to existing buildings. The campus and buildings are being designed to achieve LEED Silver Certification.

Sustainable design strategies were explored with the client in a series of “eco-charettes,” based on the LEED checklist. This process entailed detailed strategies for conservation, energy efficiency, and the incorporation of active and passive systems in the design.


CSDA provided architectural services for four new STEM Learning Pod buildings on four separate sites (Del Sur St., Filmore St., Daventry Pl., and Eustace St.) with one new multi-purpose room at the existing VISA High School. These buildings are a part of the Vaughn Next Century Learning Center charter school campus in Pacoima, California.

All four buildings are based on the pod concept and design of the Global Green Generation (G3) Charter School. Although the G3 School pod design was used as a basis for design, the pods vary in size and shape from site to site, due to the differing physical constraints of the individual sites. Each building varies from approximately 9,000 to 17,500 total SF and although separated, these new buildings provide a physical connection to the existing campus. Additionally, CSDA’s design provides as much green space, shade and additional parking as each site will allow.

The “Learning Pods” are large open spaces that house multiple classrooms or can be utilized as one large group learning space. These larger learning spaces facilitate the STEM (Science, Technology, Engineering, & Math) curriculum taught by providing as much flexibility as possible and state-of-the-art technology. In an effort to deliver the most energy-efficient buildings possible, CSDA designed these learning pods using California High Performance School (CHPS) guidelines and standards.


CSDA provided architectural services for the expansion of a 280-student Stanford University affiliated, public charter high school within the Sequoia Union High School District. The project was delivered from start of design to substantial completion in less than 12 months, on time and on budget.

The site features a new 20,000 sf two-story, high-performance modular classroom that was designed to exceed Title 24 energy savings standards by 40 percent and deliver a 100-year service life for the shell and structure. The building includes nine standard classrooms, a computer lab, a full chemistry lab with fume hoods, and a chemical storage room with an observation window for experiments that might require separation of the students from the reaction/event.

Additional renovations to the site include .88 acres of landscape improvements which utilize bio-filtration plants to treat 100 percent of stormwater onsite prior to draining to the bay. Also included were a staff parking lot, new basketball and volleyball courts, and a new courtyard.

The site, which is composed of fill over bay mud, required extensive ground improvements to prevent liquefaction. An incremental approval process with the San Diego Office of DSA allowed the team to expedite both hazardous soil remediation and ground densification operations while the balance of work was still in design and approvals.
