Collège Amadou Hampaté Bâ
Collège Amadou Hampaté Bâ is a school refurbishment project that utilized local materials, with adaptation of vernacular techniques to respond to the challenging climatic conditions and create beautiful and comfortable spaces conducive to learning.
Collège Amadou Hampaté Bâ is a school refurbishment project with 970 m2 of total floor area, designed by Article 25 that utilized local materials, with adaptation of vernacular techniques to respond to the challenging climatic conditions and create beautiful and comfortable spaces conducive to learning. The principle building material was locally quarried laterite stone, which is a much underutilized resource in Niger. The project that now houses 1200 children included refurbishment of existing classrooms and addition of 5 new classroom blocks (totaling 20 classrooms), along with new administrative facilities, an assembly hall, library and latrine blocks, Upgrades of water and electrical services to improve the school’s resilience to intermittent municipal supply.
12000 Children from low-income community within Niamey and administrative staff
The primary construction material used for the project is Laterite stone blocks for the walls quarried from the neighborhood. The stone blocks stand on concrete floor slabs that rest on concrete foundations. The roofing structure is a composite of laterite blocks, steel trusses, timber and aluminum sheets as cover material that rest on a reinforced concrete.
Building designs generally fall under architectural copyright and they are protected in Niger by Decree No. 93 027 of March 30, 1993, on Copyright, Neighboring Rights and Folklore
The client Collège Amadou Hampaté Bâ, partnered with consultancy organizations to design, construct and supervise the school refurbishment for use by the community school going children.
It is a unique project just for the Niamey site.

List of suitable climates for use of this design
The buildings used laterite stone blocks measuring 15 x 15 x 30 cm as its primary material. The stone blocks are laid in english to create a 30 cm thick wall that stands on a concrete slab, sitting on a concrete foundation.
Niamey’s climate is extremely challenging, with daytime temperatures in the 30s all year round, and regularly reaching well above 40 celsius degrees in the warmer months.To solve this, the design introduces a passive cooling enabled by the block walls and a double layer of the roof that comprises Earth brick vaults from the classroom ceiling, with a lightweight flying metal roof above. The roof angle and building orientation help pull air through the roof cavity.
Trained youths in bid to replicate the construction technology within the community.
Components are replaced or modified on site on a case by case basis. Components such as windows, doors, roof truss etc.
The building was designed as a sustainable building to use passive design principles to mitigate the high temperatures, and create comfortable spaces for teaching and learning in Niamey’s extreme climate that varies from 30s all year round, and regularly reaching well above 40 celsius degrees in the warmer months.
