Designation as a Conservation Area does not commit an area, museum like, to a fixed point in time, but rather, it enthusiastically embraces change.

Probably the most important effect of designation is the greater emphasis placed on matters of design when planning new development. The District Council is required to pay "special attention to the desirability of preserving or enhancing the character or appearance of that area" when considering planning applications. This does not mean that nothing will ever change, but rather that new development will respect the established character of the area. New buildings will usually be similar to the existing in design, materials and scale. Planning applications in Conservation Areas are also advertised more widely than normal, with a notice being displayed on site and in the local press.

In considering planning applications within Conservation Areas, the Council require more detailed drawings and information on the proposed development and will insist on full rather than outline applications.
