Yep, exactly that. We'd drive up from the left of the picture, past the house, reverse in. Drive straight out.
Trying to avoid having any opening on the public footpath, and would then be too easy to drive over the paving for the blind.
There's a smaller pillar to the left of my red mark and a bigger pillar to the right, we are taking out a middle section.
The gap is actually almost 12 foot wide! - dodgy camera angle.
Thanks all. Appreciate your time.
