L-Shaped Dormer
An L-shaped dormer combines a rear dormer with an additional dormer over the rear extension (where applicable), forming an ‘L’ shape when viewed from above. Perfect for Victorian and Edwardian homes.
- Best for: Homes with rear kitchen extensions or outrigger roofs.
- Benefits:
- Maximises floor area across two roof sections
- Ideal for creating multiple rooms upstairs
- Adds significant value to period properties
“An L-shaped dormer is great for properties that have been extended before. It allows you to fully utilise the loft space and often create multiple rooms.”

A single sloping roof extending downward from the main roof, often used on the rear.

Side Dormer
Built into the side of the property, typically for homes with a side-facing roof slope.

Exterior Finish Options
Exterior finishes can include tile or slate hanging, render, or cladding. The choice of materials will be matched to the existing property to ensure a cohesive look
Planning Permission
In many cases, dormer conversions fall under permitted development rights and do not require planning permission. However, if your property is in a conservation area or the conversion exceeds certain limits, planning permission may be necessary.
