SPEC Toolbox Product Integrations

Mass Timber Technologies (MTT), based in Johannesburg, is a leading innovator in engineered timber prefabrication across Southern Africa. Specialising in Cross-Laminated Timber (CLT) and Glued-Laminated Timber (GLT), MTT delivers precision-engineered structural panels, beams, and columns designed for speed, performance, and sustainability.

Our advanced facility manages the complete value chain, from lumber grading through robotic cutting, pressing, and CNC finishing, ensuring production integrity and exceptional tolerances. This enables architects, engineers, quantity surveyors and contractors to build with confidence, achieving shorter construction timelines, reduced carbon emissions, and lower on-site resource use.

By integrating digital design workflows directly into SPEC Toolbox, MTT empowers design teams to model, optimise, and specify CLT and GLT systems seamlessly, with solutions adapted to worldwide climates and regulatory standards.

MTT is part of the Sustainabuild Group, a multi-disciplinary platform offering integrated solutions for sustainable construction across Africa. Through Sustainabuild, clients have access to a full ecosystem of expertise and services, from timber engineering and prefabrication to design consultancy, building systems, and circular construction strategies. This wider group affiliation reinforces MTT’s capacity to deliver not just products, but complete solutions for the future of building in Africa and the rest of the world.

With a commitment to technological innovation, sustainable building practices, and structural expertise, MTT is shaping the future of high-performance timber construction in Africa and beyond.
