The new classroom building draws from a palette of materials that were already established through recent work done at the high school. The main roof form for the building is a shed roof, which slopes from east to west. The high point of the shed roof faces the taller massing of the gymnasium on the west side. The low side of the shed relates to the massing of smaller, multifamily residential units on the east side. Brick constitutes the main body. Just above the brick, the wall plane steps back two feet in order to create a clear distinction between roof plane and the brick wall.

Each point of entry is highlighted by a change in form and material. The north and south entries are composed of louvered steel and glass boxes. At the east and west entries there are towers which use a combination of corrugated metal and extruded rectangular forms. The towers serve as elements, which provide a visual break to the 241-foot long brick facade.

The building uses a wide range of sustainable materials and techniques and was designed to meet LEED® Silver criteria. Concrete floors are used instead of the traditional VCT flooring. Both steel louvers and sunscreens are used as a means to control building heat gain. The sunscreens, composed of steel grating and steel outriggers, are placed directly above the windows at all classroom locations. Each classroom also has operable windows which allow for air circulation and for passive cooling to occur. The steel louvers are used to screen large expanses of glazing found at the north, south, and west entrance towers. The east and west towers also have north facing clerestories which pull in additional light to the lobby spaces below.
