Unified composite model in which the metacolor symmetry group and the standard model group are embedded in a single group of the SU(N) type and unified above a certain energy scale are constructed. Such unification scheme provides constraints to the composite model building. The proposed models are analyzed in terms of the complementarity principle to show that they satisfy the physics Higgs phase criterion. In order to obtain a metacolor scale of the order of a few tens TeV, the rank of the unification group is restricted.
