Site constraints 5

Article 4 direction

Whole District excluding the Town of Chesham - Poultry production.. Named permitted development rights are withdrawn here.

An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.

Protected tree 7 m away: The Chiltern District Council (Land at Chilterns, Lincoln Park, Amersham) Tree Preservation Order 19, order TPO/1988/006

4 protected trees within 15 m. Named in a tree preservation order: work to it, its roots included, needs the council's consent first.

Root protection areas reach up to 15 m from a large tree, so an extension or new foundations this close usually needs a tree survey. Only some councils publish their single trees, and a position can be approximate: the order at the council is the definitive record, and no tree shown is not proof there is none.
