How big is your patch?

The back garden is around 125 square metres, but there's a greenhouse, shed, steps, and rockery/retaining wall taking up some of that space (as well as some extra paving slabs that will probably be going). I'm not sure if I'll keep the shed as I have a big garage that isn't easily accessible by car (even if I had one!) so there's no shortage of storage space - I suspect the shed is only there because my vendor and her husband got to the point where they couldn't carry the lawnmower up the garden anymore. There's also a bit of extra patio space by the house where I could squeeze some containers, as well as some space near the garage/carport where anything happy in partial shade could be in containers (there are quite a few containers of bulbs, a rose, ivy, and other things there already).

The front garden is around another 30 square metres but is north facing and by the road. I still reckon I can put it to good use

Edit: Google says that my total of 155 square metres is around a 30th of an acre. One day, I hope to get up to around a third of an acre, so I have a bit of a way to go. My Grandma's garden is around a third of an acre (rural NE Lincolnshire where the land is cheap!) and I think that would be a great size for a food forest/chicken run/wildlife-friendly garden.
