Construction, products and techniques are constantly evolving. This includes building facades and the trades linked to it. The C3 Engineering design consultancy was created in 2014 with a view to bringing together the competences and experiences of each one of us, in order to offer our clients high-performance solutions for their construction and renovation projects.



With a team of experienced people, all with between ten and twenty years experience in facades (mirrors and glazed facades, metal work, waterproofing and cladding, structures, architects…) our agency can respond to the technical demands in various domains, such as glass facades, metal structures (aluminium, steel…), cladded facades, metal work or waterproofing. The strengths of our team lie in our extensive skill base at every level of intervention. Our team is made up of 12 people: project managers, engineers, calculators and projectors, who intervene in perfect cohesion on all our projects. Currently our range of interventions includes traditional structures as well as modern, innovative ones. We form a veritable link between the architect and the different technical teams and our facade engineering consultancy is a guarantee for smooth-running, successful projects, and cohesion between the different contractors.
