  We briefly review the Coset Space Dimensional Reduction (CSDR) programme and
the best model constructed so far and then we present some details of the
corresponding programme in the case that the extra dimensions are considered to
be fuzzy. In particular, we present a four-dimensional $\mathcal{N} = 4$ Super
Yang Mills Theory, orbifolded by $\mathbb{Z}_3$, which mimics the behaviour of
a dimensionally reduced $\mathcal{N} = 1$, 10-dimensional gauge theory over a
set of fuzzy spheres at intermediate high scales and leads to the trinification
GUT $SU(3)^3$ at slightly lower, which in turn can be spontaneously broken to
the MSSM in low scales.
