The brief was for a new place on the school grounds to house the school’s library books and to be used as a flexible learning space. The small challenging site for the new building, previously an unused play area adjacent to the assembly hall, is characterised as a primary circulation route to yr 1 + 2 classrooms at the rear of the school. The site is also defined by two different boundary conditions; an external wall forming part of the Kentish Town Community Centre building to the west and a large chestnut tree on the boundary of a neighbouring rear garden to the south. The new building consists of a flexible learning space, storage area, staff and children’s WCs. The design strategy respects the existing circulation around the main school building and creates a new outdoor space in front of the new building. The corner of the building is made up of a sliding, wrapping glazed wall, which can completely open to allow learning activities from the internal space to spill out onto the newly created external forecourt, transforming it into an outdoor extension of the classroom. The internal space receives excellent daylight and natural ventilation with a row of north facing roof windows and high level strip windows along the southern boundary. The exterior of the building is dressed with FSC certified larch cladding.
