The Kattine old house, located in Kessrouan, was the last remaining house with a mud roof slab. In order to preserve the integrity of the house and ensure its longevity, our team obtained the necessary permits and conducted a comprehensive rehabilitation project. The project involved the removal of the old mud slab and the installation of a new, reinforced concrete slab. Additionally, the exterior of the house was enhanced with stone cladding and sandblasting techniques were utilized for surface preparation. These interventions ensured the durability and stability of the house, while also preserving its traditional architectural character.
