Right, the garden is about 9.5m side to side, and about 7 front to back, so not huge.
I've really taken on board the idea of keeping the planting simple, with one idea. I very much like the idea of a tree beside the patio as I love the idea of foliage above and around.
There are glass patio doors leading down out onto the patio, the kitchen window is by where the dwarf apple is at the bottom of the picture, and there is a glass door at the top of the steps on the right.
The floor level of the house is about 1m above the patio, which is in turn about 40cm above the garden level. This is why we can't do a pergola on the patio, the top of the patio doors is too high in comparison to the patio surface.
I'm nervous about getting rid of the lawn, as I've seen on other threads how people buying family sized homes really like them. DD is above the age of a paddling pool, but I think there's something nice about being able to sit on a blanket on a lawn (ideally under a tree).
I LOVE multi stem birch, and also anything with interesting bark. I think Rowans are actually rather boring, so not convinced that should go in the middle of the garden, maybe a birch or flowering cherry?
