Phenomenological model building in Mtheory has always been limited by a
lack of concrete examples of compact G2 manifolds. Nevertheless, the local
geometric structures giving rise to massless charged matter and gauge
symmetries in Mtheory are extremely well known, and have even been
classified (arXiv:0804.1132). Perhaps surprisingly, there exists one
particular local geometry (essentially unique) which by itself gives rise to
three full families of the standard modelall living at a single point in
the compactification manifold. This particular starting point is extremely
constrained, and has many features that could lead to the first concrete,
phenomenologically viable model in Mtheory. In this talk, we will review
all the essential tools required for model building in Mtheory, leading up
to the construction and exploration of this particularly interesting model.
