L-shaped Dormer Loft Conversion

Popular on period properties, an L-shaped dormer loft conversion creates a large space that can usually create multiple rooms such as two bedrooms plus a bathroom, a large bedroom and bathroom or a variety of other configurations

What is an L-shaped dormer loft conversion?

An L-shaped dormer loft conversion is where two dormer builds are connected together. One dormer is built on the main roof and the other on the rear roof to create the distinctive L-shape. Because of this shape, L-shaped dormers are usually only suitable for Victorian and Edwardian properties where there is a back addition at the rear to house the kitchen and bathroom. However they are the best way to extend this type of property, particularly if it is a mid-terrace and at the same time create a nice large space to work with.

Do L-shaped dormer loft conversions in London require planning permission?

L-shaped dormer loft conversions generally do not require planning permission. However, at Simply Loft we always recommend that you check your Local Authority’s planning policy requirements as these can vary. They can also be affected if you or a previous owner has made other extensions or improvements.

Even if you do not require planning permission, you will need building regulations approval once your London loft conversion is completed. You can view our FAQs to find out more about processes and requirements for loft conversions in London.
