Restrictions within conservation areas
In conservation areas, normal 'permitted development' rights (permission granted automatically for certain works to single dwelling houses) are restricted. This enables more control over the size, design and location of extensions and alterations.
Is planning permission required?
Further restrictions affecting specific conservation areas
Four conservation areas are subject to further restrictions on development: Brentham Garden Estate, Hanger Hill Garden Estate and Hanger Hill (Haymills) Estate (under Article 4 of the General Permitted Development Order).
In these areas planning permission must be obtained for all residential extensions and minor alterations, porches, exterior painting, means of enclosure, vehicular access and hardstandings (on the Haymills Estate means of enclosure, minor alterations and extensions to the rear of the dwelling house are not included in the Article 4 Direction).
