I thought you were allowed outbuildings up to 4 metres high ?.
There are various constraints if it's to be "permitted development". One
is n0t more than 30 sq m floor area inside. Another is not more than
2.5m high IF within 2m of a boundary, which this is. 4m would be lovely.
But.

If it exceeds 30 sq m it can still be erected under permitted development but you have to conform to building regulations.
