I divided my back garden into two - bottom half has large double gate from the drive, it was gravel over hardcore. I had a natural pond dug which goes up and down with teh water table so i need to deepen it - the ducks are sometiems just standing in it.
Top half is for me and teh dogs, but I have garden seats round the pond so I can go and fraternise with them on fine days and get peace from the scruffs
Grass, moss and wild flowers as well as nettle and thistles appeared over the two years since the fence went up (made of pallets by my son), so much of the gravel can't be seen, but it means that the birds haven't trashed the place and their poop gets washed into the hardcore underneath. keeps their feet tidy too. They have inside (at night, with pop hole to close them in) and outside dog runs, with a small attached covered dog run if they have to be restrained for any reason (bird flu lock down for example)
Works for me and my immediate neighbours.
