Taking shape nicely Allyne. This latest photo gives a better idea of what you are aiming at....and your aim is true!
I hope you don't mind me sticking my dippy in again mate, but how about this.....Where dios are concerned, never throw anything away, things can always be re-cycled.
Take your gate for instance, I can't see what's wrong with it, but if you don't like it, keep it, but wreck it more and leave it lying on it's side with grass growing through it, then fit your new one. It would make a nice mini feature!
Putting my ex joiner's hat on, see the diagonal gate brace? Make sure the hinges are on the left as you look at the photo with the brace going up to the opposite side. The brace is to stop the gate sagging, but you could well know that already!lol
Yep, looking good.
Cheers,
Ron
