32 Freemantle Street London Southwark SE17 2JP
Works to a tree in a conservation area: T1. Pear Tree. In rear garden of 32 Freemantle Street. Proposed works: Removal by sectional felling. Reasons for desired works: The tree consumes most of the space in the small rear garden and is creating an excessively gloomy environment in the garden and back rooms of the flat. It is fairly tall for a pear tree and not appropriate for such a small garden.
