There seem to be a fair few experts on planning so thought I'd ask here
Basically, there's a patch of our front "garden" which is nothing but an annoying patch of lawn which needs mowing and never gets used.
It abuts our drive which is higher and sloping - probably 1.5m where it joins the garage, 50cm where it ends.
My idea is to bring the current side-gate/fence forward, from parallel to the house, to just short of the (unadopted) road. We can then put the trampoline there - freeing up space in the back-garden, and actually putting that patch of front garden to use.
On the below link, removing the yellow line, and putting in the red one.

Does this need planning permission?
