I don't as yet
But I am thinking that I want to put in some silver birch trees and Japanese Maple or something for some colour in autumn. I'm also going to plant some Daphne right outside my front door -I just LOVE the smell! hopefully the majority of the rest will be natives and some ground covers... I probably wont put any lawn out the front. Maybe some roses would be nice along the driveway too.
They lay out and the rest of it I'm all a bit unsure about to be honest, but like you I will need to do a garden plan soonish too but I'm trying to wait until I have my driveway in and all the builders crap gone to get a good idea of the space and how it will be used (path ways, access to meter box etc)
