Here are a few pictures of another shared garden, as discussed at the AGM, where hedges, some of lavender, some of rosemary, one of privet (I think) have been used to create spaces within the garden. It’s in Suffolk, where they have been experiencing drought conditions since the spring, and the gardeners come once a month. We could have such a hedge between the car park area and the main piece of grass (I can’t really call it a lawn). It should help protect the grass, and provide privacy for residents who want to sit outside. Similarly, hedges of lavender or rosemary could be planted between the parking spaces and the flats to screen noise and lights.
There’s also one picture of a pergola.
