In this project, two material systems clash and combine to create a kindergarten with unique spatial experiences in each classroom.The first material system is a steel grid extrapolated from the roof structure of the existing shed. This system is the primary basis for classroom organization and frames the second-floor space intended for playful activity. The second material system is comprised of of large-scale wood volumes that disrupt the rigid steel grid at non-orthogonal angles. These occupiable volumes serve as the bathrooms, offices, and a circulation corridor. While program is clearly denoted by the contrast in material, there are moments of intersection between the two systems, such as the skylights and window frames, that suggest interdependence between spaces as well as the exterior site.
