Skirting and Skirting Boards off the level!

We recently moved into a brand new (to us) office, which is an absolutely ancient building with wobbly floors boards, dodgy walls, old wooden windows and simplistic skirting boards. The window sills are all off level, the door frames are too low, and the hallway skirting is all out of square to the rest of the building… 

So much for building regulations eh? !
