The Vision to transform Casey Middle School was established in 2007 and
a set of guiding principles was developed for both curriculum and
building form. Along with Educational Specifications, input was gathered
from district specialists, teachers, parents, students, administrators
and the Casey Design Advisory Team to define the design of the
600-student Middle School.
Program constraints and unstable soils determined the original 1924
building could not be saved without great expense. However, two exterior
walls with beautiful terra cotta panels, intricate brick work and
original light fixtures were preserved to maintain the school's historic
The architecture of the new school building uses contemporary forms to
contrast with the historic walls. A new main entry was created opening
into the commons, which serves as the cafeteria and a social space for
students. The library uses the historic façade for its full three-story
space. One of the original entries remains as a secondary entry into the
library. Natural daylighting lights classrooms while tubular skylights
balance the natural light in the rear of the room in both main and upper
The 8.4-acre urban site incorporates plazas bordering the south side of
the building. A landscaped bio-swale winds its way from the entry around
community gardens and through drive lanes. A plaza highlights the
existing walls of the original 1924 school building, while creating an
outdoor space for school or community gathering.
The school accommodates after hours use by closing classroom areas while
leaving the gym and auditorium open to the community. Both have separate
entrances. The auditorium seats 350 people.
Classrooms are grouped in teaching arrangements around common spaces
where student lockers, study/break-out space and teacher planning areas
are located. These clusters of classrooms include a flex room which can
open to the common space. Flex rooms may be used for seminars and small
Enabling students to socialize in multiple environments was important to
the program. Common spaces, shared work spaces and integrated curriculum
all support this goal. Additionally, not only incorporating sustainable
design into the building but also incorporating it into the curriculum
is an evolving goal for the school.
- Site re-use, preserving the existing infrastructure as well as
community transportation connections.
- Under building parking to accommodate approximately 50% of the needed

- A photovoltaic arbor doubles as covered bicycle parking.
- Xeriscaping and bioswales are integrated into the design to reduce
irrigation needs and stormwater runoff.
- Approximately 80% of required lighting levels are achieved from
controlled natural daylight.
- 84% of construction waste was diverted from the landfill.
- Recycled and low VOC materials are used throughout.
- Heating and cooling occurs by a water to air ground source heat pump
- Green roof demonstration area.
- Students identified existing school artifacts to be re-used in the new
school, such as wood flooring from the gym, benches and a climbing wall.
