Here are the gates. Notice, in traditional DIY fashion, I have yet to paint/treat the new gate, hence its aged look. The old gate was really falling apart with pointy bits sticking out and a big hole for the dog to stick her had through. I could not wait (forever in this cost-cutting climate) for the MOD to replace their gate, so I made another using the leftover wood from a pine bed (always save this stuff - you never know when it will come in useful).
In fact, the only expense was a new latch (£9.99), the equivalent wood would have cost about £25 and a new gate already constructed would have cost £50+.
