Architectural Pioneering Consultants (APC) takes on a significant venture with the expansion of Mkombozi Primary School, situated in the Chamazi region, Tanzania. Commissioned by the Sisters of the Holy Redeemer, a Tanzanian religious order, the project aims to extend the existing nursery school to include a Montessori primary school and potentially a secondary school, accompanied by essential support facilities. The expansion aligns with the educational vision of the Sisters, who are actively involved in the Mtwara region and Dar es Salaam.

Architectural Innovation with Local Materials

APC ventures into innovative architectural solutions, incorporating locally burnt clay bricks to construct pressure-based load-bearing structures such as arches, domes, and vaults. This approach not only explores sustainable construction but also aligns with the Tanzanian context, where the use of such materials is rooted in traditional, experience-based knowledge. The utilization of locally sourced materials reduces reliance on imports and supports the local value chain, presenting a significant step towards self-sufficiency.

Designing for Sustainability and Adaptation

The architectural exploration begins with sourcing suitable raw materials and enhancing the brick production process. The simplified design, featuring vaulted roofs supported by concrete columns and ring beams, ensures earthquake resilience and ease of construction. Designed to address the hot-humid climate, the vaults facilitate air circulation, allowing hot air to escape, while a simple sheet metal finish provides essential waterproofing against seasonal rains. The vaulted design not only enhances thermal comfort but also contributes to improved acoustics within the classroom spaces. The narrow floor plans promote cross ventilation, enhancing the overall environmental sustainability of the structure.

Innovative Timber Walkway: A Sustainable Connection

A 100-meter covered timber walkway serves as a vital element, connecting new and upcoming classrooms. Beyond providing a shaded circulation area, this walkway doubles as an outdoor gathering and play space. Recognizing the depletion of indigenous hardwood supplies, APC employs reciprocal timber framework structures. This method allows for wide spans by combining shorter timber members, utilizing smaller, younger pieces of wood from timber farms. This approach prioritizes sustainable practices, avoiding the need to fell old-growth trees for construction. The engineering complexity lies in assembly, a process that, while requiring advanced skills, can often be accomplished without the need for complex machinery.

Mkombozi Primary School’s expansion project not only signifies a commitment to education but also showcases a pioneering approach in sustainable architecture, blending innovation with traditional wisdom for a brighter educational future in Tanzania.
