What small tree for outside front window, limited frontage

[SpaSushi]

I would like to plant a small tree outside my front window for some privacy/screening and possibly a climber to look nice.
Problem being g there is only about 1.2m/4ft of "garden" between my hoise and a footpath so it needs to be a compact tree and not damage walks/footpath
The window is about 80 cm from the ground and 1.5m wide

Hopefully photo attached shows .( not my house but its similar)

I was thinking:
Salix flamingo
Japanese Acer
Dwarf crab apple
Dwarf flowering cherry

And then clematis or jasmine climbing ?

Would any of these cause problems with roots/size?

What about climbers ?
Should i go for one tree in the middle of the window( its wide) or a couple?
Should i balance with one on the other side if the door ( where I'm semi detached?)

I don't think a tree in front of the window is a good idea. We have a climber that keeps scratching on our glass and it's annoying!

What about a small tree in a planter that can be moved around?

Thank you @FrancisCrawford i love fairy light /climber pyramid idea, not sure its high enough for the window 🤔 will have to look them up.

@redwoodmazza i had thought of pots, but i tend to kill potted things...

bamboo in pots ?

or goldcrest lemon scented conifers?

Not sure there's enough space for a tree that close to the house. A climbing rose would be lovely trained around the window.

This is a nice little tree that you can keep as standard, its evergreen as well, Photinia “little robin tree”

Thank you

Have you considered a large plant inside at the window for some privacy?
