Tandem Development - Policy and Acceptability

Tandem development (where one house is placed directly behind another sharing access) is generally unacceptable due to impact on neighbouring amenity and area character. It may only be considered in exceptional circumstances where plots are sufficiently large to achieve appropriate separation distances and proposals are sensitively designed.

Tandem development is a form of backland development where one new house is placed directly behind another either sharing the same, or an additional driveway/access. This form of development is generally unacceptable because of the consequential impact on the amenity of the surrounding dwellings and the adverse impact on the general character of an area. In exceptional circumstances, where plots are of a sufficiently large size to achieve appropriate separation distances between houses (see 'Privacy' below), proposals which are sensitively designed to limit the impact on neighbouring properties may be considered.
