  We present a simple N=1 five-dimensional model where the fifth dimension is
compactified on the orbifold $S^1/Z_2$. Non-chiral matter lives in the bulk of
the fifth dimension (five dimensions) while chiral matter lives on the fixed
points of the orbifold (four-dimensional boundaries). The massless sector
constitutes the Minimal Supersymmetric Standard Model while the massive modes
rearrange in N=2 supermultiplets. After supersymmetry breaking by the
Scherk-Schwarz mechanism the zero modes can be reduced to the
non-supersymmetric Standard Model.
