The extension is positioned in the south-east corner of the existing playground on Old Mountpleasant. The special needs rooms are on ground floor level with doors to the playground. The arts and crafts room is upstairs with northlight rooflights to give a ‘studio’ rather than ‘classroom’ character to the room. The ground floor meeting room faces into an existing courtyard beside the east end stair block and the first floor staff room overlooks the lane connecting Ranelagh Road to Old Mountpleasant. The original school building was designed as a quartet of brick classroom houses along Ranelagh Road with a different scale of structure and material in the verandas on the playground side. The extension is designed to be consistent with the original design by the addition of a new brick house on the laneway with a sloping room form to the playground. Reclaimed Dolphin’s Barn brick walls, terned coated steel roof and iroko window elements match the materials of the existing building.
