DM18: Residential Basement Development and Light Wells
- Householder extensions to existing basements, and the construction of new basements, including in existing dwellings will only be permitted where it can be demonstrated that the proposal:
- Will not adversely affect the structural stability of the application building, neighbouring buildings and other infrastructure, including the adjoining highway, having regard to local geological conditions;
- Does not increase flood risk to the property and nearby properties from any source (see Policy DM24);
- Avoids harm to the appearance or setting of the property or the established character of the surrounding area;
- Will not adversely impact the amenity of adjoining properties by reason of noise or increased levels of internal or external activity;
- Will not adversely impact the local natural and historic environment;
- And, where the proposed basement extends beneath the garden area:
- Will not cause loss, damage or long-term threat to trees of townscape or amenity value;
- Maintains adequate soil depth satisfactory for preservation of landscaping consistent with neighbouring properties;
- And during the construction phase:
- Will not cause harm to pedestrian, cycle, vehicular and road safety, adversely affect bus or other transport operations, significantly increase traffic congestion, nor place unreasonable inconvenience on the day to day life of those living, working or visiting nearby; and
- Will minimise construction impacts such as noise, vibration and dust for the duration of the works.
- Proposals for basements must not include habitable rooms or other sensitive uses in areas prone to flooding where there is no reasonable means of escape.
- In determining applications for light wells, the Council will consider whether:
- The architectural character of the building is protected;
- The character and appearance of the surrounding area is harmed; and
- The development results in the loss of more than 50% of the front garden or amenity area.
