This gives an additional 8" extra height around the whole shed. The standard height is:
Apex - 7ft to top of apex & 5ft 10 to the eaves
Pent - 7ft at the front and 6ft at the back.
This is perfect for apex sheds where the door is required to be in the long side.
Also for tall people or summer houses which will be used regularly to let you move around freely.
