  A five dimensional model containing both left-right and quark-lepton
symmetries is constructed, with the gauge group broken by a combination of
orbifold compactification and the Higgs mechanism. An analysis of the gauge and
scalar sectors is performed and it is shown that the 5d model admits a simpler
scalar sector. Bounds on the relevant symmetry breaking scales are obtained and
reveal that two neutral gauge bosons may appear in the TeV energy range to be
explored by the LHC. Split fermions are employed to remove the mass relations
implied by the quark-lepton symmetry and the necessary fermion localisation is
achieved by introducing bulk scalars with kink vacuum profiles. The symmetries
of the model constrain the Yukawa sector, which in turn severely constrains the
extent to which realistic split fermion scenarios may be realized in the
absence of Yukawa coupling hierarchies. Nevertheless we present two interesting
one generation constructs. One of these provides a rationale for $m_t>m_b,
m_{\tau}$ and $m_\nu\ll m_t$ with Yukawa parameters which vary by only a factor
of five. The other also suppresses the proton decay rate by spatially
separating quarks and leptons but requires a Yukawa parameter hierarchy of
order $10^2$.
