Measuring height - permitted development

[oculushut]

Hi,

Under permitted development, I believe that we can have the extended part of a single storey extension as tall as 4m in height.

If we have a parapet wall similar to that shown in the following drawing then is it A or B that needs to be no higher than 4m?

Thanks!

Height is 'B'.

Excellent - thanks!

Helpfully, in 2016, the Technical Guidance replaced the word 'should' with the word 'may' - or was it the other way around? Anyway, no-one really has a clue.

@ Leofric - I take it you don't like the principle of permitted development?!

Nothing against permitted development in principle , within reason. I don't ,for example , consider an 8 metre extension is ' within reason '.
