We faced a difficult challenge in creating spaces for a progressive nursery school in a cellar space adjoined by an exterior courtyard. So we took the structural limitations and made them part of the fun. Since it’s below ground, and the existing layout was so unruly, we designed a meandering tunnel that opens to each classroom. Kids, like adults, need a variety of spaces. Some like to be in large groups, others in smaller ones, though most want a bit of each. We focused the design of the classrooms around this. Within each room we created niches where two kids can sit together, or a teacher can sit and face a smaller group.
