Looked at a job for a local church on the way home. The 'committee' were
present.

A parishioner has given them a load of kitchen units only a few years old
and they want me to rip out the tatty old units in the hall & fit the newish
ones.

A plan was produced. Sink to remain where it was on the left end of the
wall, built in oven & hob on the right of it.

Obvious problem, the waste from the sink runs through the units & along the
length of the wall around 2' above the floor & enters a soil pipe - due to
various other fittings it couldn't be fitted lower down. The oven goes
right to the back of the unit.

Easy answer.

Fit MDF false wall and tile it.
