Our study starts with a sequence of puzzles that include (a) at which level μ problem involving electroweak symmetry breaking can be solved; (b) in which paradigm masses of superpartners in the third family can be lighter than in the first two families; (c) whether it is possible to accommodate 125 GeV Higgs boson simultaneously; and (d) how natural such paradigm is. These issues are considered in the context of two-site SUSY models. Both the MSSM and NMSSM as low-energy effective theory below the scale of two-site gauge symmetry breaking are investigated. We find that the fine tuning can be indeed reduced in comparison with ordinary MSSM with mh=125 GeV. In general, the fine tuning parameter Δ is in the range of 20-400.
