I have 3 sheds, approximate ages 10, 20 and 30 years and in various stages
of bio-degradation.

I would like to replace them with one robust over-engineered "mother of all
sheds".

* Concrete slab on DPC
* 3m x 5m area
* 19mm Constructional cladding TGV with vapour barrier on 4x2 frame
* Apex roof
* More than 5m from existing house, in back garden
* More than 2m from any boundary
* No neighbour objection (in fact positive support)

In having a healthy experience-based disrespect for council bureaucrats I do
not want to require any kind of building control or planning permission at
all.

Q. Ideally I would like to build a brick wall (6-8 courses) with the
timber section of the shed above that. In doing this (or even thinking
this) am I exposing myself to flak from the regs police?

Local council web resources are very unhelpful. When is a shed not a
shed...but an "outbuilding"?
