You have enough space for a simple, small, sturdy greenhouse (maybe 10x20 ft) and a bunch of beds for basics like tomatoes, peppers, cucumbers, salads, etc.
The back was once a garden centre split into 3 plots we got the middle plot 2.7 acres not including house plot. Was a livery but restricted use was a pain.
We had 2 patches one wish potato's onions, salad onions, cabbage, cauli, leeks, giant courgettes all salads. Then rhubarb (yuk) and sweet grapes on the wall, 4 vines. The other had runner beans, tomatoes strawberries, raspberries, radishes. Had a good fews years till we had a garage fire plus starting my new venture which has taken way to much of my time up.
