Reusable aluminium formwork is being used to construct 1,042 affordable housing units across 11 blocks at Konza Technopolis, replacing conventional blockwork and much of the plastering process.

The aluminium panels, imported from South Korea by supplier Kumkang, act as concrete moulds that allow entire wall sections to be cast in situ, eliminating the need for separate bricklaying and extensive finishing.

Each wall is 160 mm thick, enabling lighter foundations on the site's weak soils and reducing the volume of concrete and reinforcement required below ground.

Engineer Caleb Chege, part of the supervising consortium, said the system has lowered construction costs and sped up the build, with about 78 floors completed between January and the interview date.

The panels are reusable across different sections of the development, cutting carpentry needs and reducing finishing work to a simple skim coat and undercoat after concrete curing.

Standardised door and window dimensions are being produced by local Jua Kali artisans, creating a supply chain for prefabricated components that are installed on site.

According to Chege, the uniform dimensions allow these artisans to mass‑produce components in their workshops before delivery, linking the project to the informal sector.

The development includes social, affordable and market‑rate housing, forming part of the broader residential infrastructure planned for Konza Technopolis.
