The minimal supersymmetric standard model, and extensions, have stringentupper bounds on the mass of the lightest Higgs boson if perturbativity up tothe Planck scale is assumed. We argue that these bounds are softenedtremendously if the Higgs is charged under an asymptotically free gauge group.We present a model with an additional SU(2) gauge group which easily producesHiggs masses above 200 GeV while avoiding electroweak constraints. If oneallows some fine-tuning of the high-scale value of the gauge coupling, Higgsmasses greater than 350 GeV are achieved. Unification of couplings is predictedto similar accuracy as in the minimal supersymmetric standard model with onlysmall deviations at the two-loop level.Comment: 10 pages, JHEP3, clarifications added in sections 2 and conclusions, version to be published in JHE
