2 Article 4 directions
Article 4 Direction relating to Houses in Multiple Occupation (HIMO) - Non immediate direction · Olney Article 4 Direction. Named permitted development rights are withdrawn here.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.

Nearest: Electricity Generating House at Orchard House, Grade II, about 26 m from the postcode pin · 1 Grade II*, 27 Grade II
The site itself is not listed. Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.

Checked on 6 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
