The gazebo is in bits in my garage so I’ve had to guess the height.
So I measured one of the poles which are 2 metres.
On diagram 5, the 2 metres goes from the floor to where it says “E.”
Obviously it’s much higher at point “A” Total height 2.8 metres.
If anyone else is interested, I forgot to mention that it was from Trentham Gardens Garden Centre so is of a more superior quality than some you can buy.
