Dormer Loft Conversions

A Dormer loft conversion is also known by dormer loft extension which is built to protrude from the existing roof slope. It is designed to create more standing and roof space for additional headroom. It is usually at the rear of the property, and the internal requires horizontal ceilings and vertical walls.

It is one of the most common types of conversions in the UK, where a part of the existing roof is removed. Then, the “box frame” structure that projects from the top of the roof height to the rear and sides create bigger space. Typically a dormer loft conversion requires a well trained loft conversion specialist but does not require building regulation or planning permission.

Dormers are typically used for UK homes to enhance their living spaces, including adding additional bedrooms, games rooms office or even standard storage space.

Types of Dormer

01/ Gable-fronted dormer

When people think about dormers, they usually imagine the gable-fronted dormer. Why? Because it is one of the most popular types of dormer used in houses today. It is also known as a ‘dog-house dormer‘. It’s a more complex dormer which consists of a gable wall extension and a new sloping roof. Gabled dormer wall extensions are built upward to reach the current ridgeline and the sloping roof which is mounted toward the gable end. It looks like little houses coming out of the house.

02/ Hipped roof dormer

This looks very similar to gable-fronted dormer, but the roofs slope on three sides of the structure. It looks aesthetically pleasing, but it does not give as much internal space or roof space as the flat roof dormer and it is more expensive due to its complexity. With hip dormers you’ll get more headspace than the shed and more horizontal space with a gable dormer.

03/ Flat roof dormer

This is a simple dormer extension mounted to either the front or rear side of the property. It provides a maximum amount of internal space because it increases the head height and also gives more natural light into your loft using a dormer window. However, it does not look as appealing as a gable-fronted or Hipped roof dormer.

04/ Shed Roof Dormer

The Shed dormer is a single-planed roof pitched at a shallower angle to the main roof structure. It is similar to a flat-roof but slopes down at an angle slightly. It usually suits a gable roof, and it extends living loft space with visual height and width.

Dormer Attics

the Pros and Cons OF Dormers

Lots of extra space

A dormer loft conversion is known for its additional loft space, built with an extension to the existing roof. Thus, it provides additional room and head height space to your attic. Height restrictions will limit you in maximising your loft, but dormers allow you to make space for big furniture that you wouldn’t otherwise have.

More natural light

Due to the extra space that a dormer provides, you would be able to choose whether to install windows, French doors or install a loft conversion with a balcony. Installing either of these offers more natural light to enter your loft. Thus, you’ll be getting much-better-ventilated space while enjoying the light of the bright sun every day through your brand new roof light.

Cost-effective

By extending the existing loft space that you have in your attic using a dormer loft conversion you can get additional floor space for an extra room or even two. It is a cost-effective way to gain more space, especially if you would choose a flat roof dormer loft conversion for your home.

Permitted Development

Most dormer loft conversions don’t need planning permission because it typically falls under the permitted development. It usually depends upon the size and the location of the planned extension, but it is better to check the local authority before starting the project.

Installation time

Dormer loft conversions take more time to construct than a Velux loft conversion, due to the alteration of the roof required to create an extension. It also makes the initial cost of the dormer loft higher than a Velux loft conversion; but, if you’re after the extra floor space and beautiful appearance and ambience, then your investment would be worth it.

Suitability

A dormer loft conversion needs more structural changes and alteration to the roof of your home; unlike the Velux loft conversion or mansard loft conversion where you only need to add a window flush to the existing roof. This means that not all properties suit this type of loft conversion. It would be necessary to do a bit of research if your roof is suitable for a dormer loft conversion. You can also determine what type of dormer loft conversion suits your home through an in-site survey by your chosen loft conversion specialist

What is a double dormer loft conversion

A double dormer loft conversion is usually constructed in two stages and is a good option if you have a flat roof area. A double dormer conversion is a double dormer extension which is a little unusual because two separate dormers are constructed on the roof slope. The flat areas either side of the dormer are dug out to house a second storey (or cellar) and additional rooms. This will also increase the volume of the space and at times include a kitchen extension and loft conversion, depending on the circumstances and design. In an attempt to hide the resulting void, the two dormers protrude slightly, or form a ledge. For this reason, double dormer loft conversions are also known as ‘Vaulted’ (two-level) conversions.

Can you add a dormer to any loft?

Simply speaking, a dormer is a style loft conversion, and requires certain height and spacing in order to be fitted.

You won’t need a specific type of house, meaning the dormer loft can be fitted to any home such as Detached, Semi- detached, terrace and even bungalow, providing you have enough space available.

What is a blind dormer?
