  We consider gauge unification in nonminimal models with extra spacetime
dimensions above the TeV scale. We study the possibility that only a a subset
of the supersymmetric standard model gauge and Higgs fields live in the higher
dimensional `bulk'. In two of the models we present, a choice for bulk MSSM
matter fields can be found that preserves approximate gauge unification. This
is true without the addition of any exotic matter multiplets, beyond the chiral
conjugate mirror fields required to make the Kaluza-Klein excitations of the
matter fields vector-like. In a third model, only a small sector of additional
matter fields is introduced. In each of these examples we show that gauge
unification can be obtained without the necessity of large string scale
threshold corrections. We comment briefly on the phenomenology of these models
in the case where the compactification scale is as low as possible.
