Here's a screen grab of our architect's design: look at the orientation of the cladding......
If I want to change the orientation (of the cladding) on any face , do I have to ask anyone?
The reason I want to change the orientation is to help make the East face ( image rhs above the green flat roof) more resistant to driving rain. I want to change it from vertical to horizontal.
As some will have read, the east face is sometimes subjected to turbulent gales
