About DeWill Consultants
Built on clear thinking. Focused on practical delivery.
DeWill Consultants is a Nairobi-based construction consultancy established in 2022, supporting clients across residential, healthcare, commercial and infrastructure projects.
Who we are
Coordination that keeps project decisions connected.
Construction projects bring together scope, design information, cost, procurement, contractors, materials and programme constraints. DeWill helps clients keep those threads visible through structured project coordination, cost advice, technical interfaces and site oversight.
Our work is shaped around the project brief, intended use, site context and the support required at each stage. Responsibilities and deliverables are agreed for each appointment, with regulated design, statutory submissions and professional certification undertaken by appropriately qualified practitioners.
