Hi Everyone,

Ok, I have been given the ok to build a small observatory in the back yard.

Because we live on a sloping block, The floor Hight from natural ground, where the pier will be, is 530mm, What I need to know, is how deep, wide, is the minimum I will need to dig for the pier support,
There are many question i have, but To make a start, doing the concrete is the first thing that needs to done.

any ideas are most welcome.

Cheers Peter
