garage wall height

[ferguson1947]

Hi all after checkin various internet sites I now realise I cannot use box profilesheets on a boundary wall of a garage so
Now looking at a prefab garage how high can the walls be seen some panals at 2000mm and 2200mm need to apply for planning so thats not an issue its a terraced house one side of garage will be next to neighbours 2 story extension so not an issue? Other side is next to boundary wall 1800mm high

I don't understand what you're asking. If you need planing why ask how high the walls can be. Ignoring the profiled sheets on a boundary thingy.
