Hammersmith & Fulham - BL1 Assessment of Lightwells

Policy information sourced from Hammersmith & Fulham Planning Guidance

BL1 Assessment of Lightwells

Any application for a lightwell will be treated on its individual planning merits, taking into account local circumstances, impact and the proposed size of the excavated area.

The following key points should be considered when creating a lightwell:

Proposals for excavation and a lightwell where the whole of the front or rear garden would be lost would normally be refused permission.
Front lightwells should be designed in accordance with the model designs for lightwells in figure BL1.
Rear lightwells should not be excessive in size and should not either on its own or in combination with a basement excavation result in the loss of more than 50% of the rear garden area in accordance with Local Plan Policy DC11.
Where they are not part of the original design, proposals to insert stairs into the front lightwell would normally be resisted.
Where a basement is being excavated to form additional living space, lightwells may be formed in the rear and/or side garden, where one exists.
