After the success of the teachers house with HYT Uganda, the Feilden Foundation were asked to work with HYT to develop their working model for a typical double classroom block within the restraints of using ISSB construction and unskilled labour who will be trained on the job. The chosen beneficiary school of Kawolo is located in Lugazi on the Kampala-Jinja highway giving the project high visibility and acting as a showcase for ISSB construction.  The project also met the needs of the school which had 238 pupils but a very limited nursery enrollment due to poor infrastructure, where they used papyrus mats in a dilapidated structure to provide shelter.

Small innovations were developed looking at active child centred learning and how the building could help encourage these in the teaching pedagogy. This led to adding high level rails for hanging displays, teaching aids and student work. Child level blackboards for drawing and actively getting involved in the lesson. An outdoor classroom located under a tree for shade, where the class could be taken outside to learn in a more interactive way. A central folding partition between the classrooms was also added which allow classes to combine in larger group learning as well as offering a space large enough that can accommodate national exams.

The foundation and HYT also developed proposals for a centre pivot window that could be opened for natural ventilation while also maintaining some additional shading and reflected natural lighting. A 20,000L ISSB water tank was also part of the construction which provides the school with further natural resources through rainwater harvesting.
