The point is that its not your house and approval was required to erect sheds, if you got approval you have no need to winge.
Seems to be a big pastime in DSO of tennents spending up big on a house they only occupy.
If someone made additions/modifucations mostly unapproved to my rental property, I would be pissed off and would want it restored to original condition.
Please dont carry on like twits with self inflammed ego's just because you are outside your home countries!
