The architect has drawn plans that meet class Q, I had given him my ideas, but he said he couldn't do them because of the roof height.
The problem with Class Q is that the dimensions, up down and round about must not exceed the size of the barn, that includes upwards, i.e. the roof line.
The architect may be over anxious and planning wouldn't care if I built a cave dwelling.
The planning delay is not due to this, but due to possible contamination.
What I'm wondering though is can I change the internal layout to what I want after approval or do I have to submit a change of application.
