Urban renewal and rampant suburbanization, like in many North American cities, has led to the decline of downtown Halifax, Nova Scotia. This thesis proposes a small-scale, child-oriented in?ll project as an alternate mode of development that retains historic fabric and repairs the urban ethos. A narrow, T-shaped, vacant lot in the heart of downtown provides the testing grounds for this intervention. Dynamic program combinations, and playful architectural propositions are presented as strategies to reintegrate children as active participants within the downtown area.
