We give an upper bound for the Bredon cohomological dimension of $G$ for this family for a certain class of groups acting on $\\mathrm{CAT}(0)$ spaces. This covers the case of Coxeter groups, Right-angled Artin groups, fundamental groups of special cube complexes and graph products of finite groups. Our construction partially answers a question of J.-F.
