To date the Citizens Foundation has set up 334 schools in the poorest communities across Pakistan. Its ultimate aim is to build and manage 1'000 schools for 400'000 children within 15 to 20 years. Its buildings are quick to construct (design/build time is generally four to five months), low-maintenance and low-cost. Simple prototypes are adapted to work with the available site. Schools in rural communities are constructed of brick masonry, while schools in urban squatter-settlements are generally finished with cement-sand plaster in a terracotta colour, to provide a calm but easily identifiable marker in chaotic surroundings.
