The project covers all existing sanitary rooms in the buildings of the 107th Primary School “Khan Krum” – a total of 7 separate rooms, serving the needs of students, teachers and administration. The interior solutions aim first of all to achieve an optimal number of separate toilet cubicles, in accordance with modern requirements for school buildings and to build a safe, ergonomic and welcoming environment for all age groups. The materials used in the project guarantee durability over time and facilitate maintenance of the sanitary appliances. The end result will be an improved and pleasant environment for all visitors, with a color and material design consistent with the given conditions, character and attraction of the building, and demonstrating the potential of architectural materials and details to educate.
