Dormer Loft Conversion




What is a Dormer?

Dormer loft conversions are one of the most common conversion types. When building this type of conversion, Dormer boxes are attached to the roof to provide light through the windows and a little more headroom where the Dormer meets the roof. They can be built quickly and more cheaply than a Mansard or Hip to Gable conversion, and the style works well with practically every home.

A lot of homeowners associate loft conversions with roof Dormers, so this loft conversion type is usually what people think of when they consider a conversion project.

What else you want to know?

If you would like to build your loft conversion as a permitted development, it’s important to check whether your home has already had any changes made. Permitted developments are assessed per house, not per owner, so even if you haven’t made any improvements you may not qualify for a permitted development if too many changes have already been made. It’s particularly important to check this if you have a kitchen extension or garage, as it’s likely these were built as permitted developments if they were added after the main house was built.

Modern Dormer Loft Conversion Types

There are four types of dormer conversion:

Flat Roof Dormer

It has a flat roof and it can extend across the entire width of the building. They are usually built at the rear of the building.

Side Dormer

If the roof ridges at your house run from front to back, a side dormer is a good option for a loft conversion. They can be built on either side of the house on a side-facing roof.

Front Pitched Dormer

Also known as a gable dormer, it is a type of small dormer having a gable roof on the top.

L-Shaped Dormer

An L-shaped dormer consists of two dormers that make a right angle to each other. They create a good amount of extra space.
