Recently, a 2d coset model with N=3 superconformal symmetry was proposed to\nbe holographic dual to a higher spin supergravity on AdS3 and the relation to\nsuperstring theory was discussed. However, away from the tensionless limit,\nthere is no higher spin symmetry and the higher spin states are massive. In\nthis paper, we examine the deformations of the coset model which preserve N=3\nsuperconformal symmetry, but break generic higher spin symmetry. We focus on\ndouble-trace type deformations which are dual to changes of boundary conditions\nfor the bulk matter fields. In the bulk theory, the symmetry breaking will\ngenerate mass for the higher spin fields. As a concrete example, we compute the\nHiggs mass of a spin 2 field both from the bulk and the boundary theory.\n
