Providing the construction meets structural and thermal requirements do
you think this type of wall would be a accepted by building control.?

I don't see why not, although you really should have some celotex in front
of the studwork, both to improve u-Value and to avoid cold bridging, which
might result in unsightly mould lines and condensation.

For new build, you can often eliminate the need for ventilation gaps through
careful selection of breathable materials.
