This is a small (3m tall) Viburnum tree in a small north facing back garden, not visible from the road. There is another Viburnum, and a bay tree in the same garden. There are other, bigger trees in adjacent gardens. This tree blocks light, and passage to the garden. Propose to remove. Plan to replace with a smaller shrub. Not another tree, given the small garden size and the number of other trees nearby.
