What are Dormer Loft Conversions?

In a nutshell, a dormer loft conversion is when a pitched roof is converted into a square-shaped structure, thereby creating walls that sit at 90-degree angles to the floor and therefore increase the space in your loft, giving you an extra room or two.

A dormer loft conversion is an extension structure built to give you additional headroom, which means that a previously unused and cramped loft can become a more ample, spacious room with new dormer windows giving you wonderful natural light. Dormer loft conversions come in various styles, and the one which is most suited to your individual home will depend on whether you have a detached, semi-detached, or terraced house and, of course, your existing roof shape.

Do dormer loft conversions require planning permission?

It depends on where you live, but dormer loft conversions don’t always require planning permission as long as they are within the permitted development conditions for your type of house. However, suppose your home is a flat or maisonette is within a conservation area or a heritage site. In that case, slightly different rules apply, so it’s worth checking before you splash any cash.

Dormer Loft Conversion Types

There are various options of loft conversions available which can add light and space to your home and include:

· The flat roof dormer loft conversion is added to the loft and is a simple structure. It’s a reasonably easy way to expand the usable space in the loft and increase head height and provide you with lots of natural light through the dormer windows.

  • A shed roof dormer loft conversion is similar to the flat roof option, but its roof slightly slopes down at an angle, and it can be constructed with different materials and is suited to houses with gable roofs.
  • The gable-fronted dormer, which is sometimes also known as a hip to a gable loft conversion, is a slightly more complicated option. It consists of a gable wall extension. This is built upwards to meet the current ridgeline, with a new sloping roof section built towards the new gable end.
  • A hipped roof dormer loft conversion is an extension where the roof slopes on all three sides of the structure, creating an aesthetically pleasing effect.


Before you decide to convert your loft and using any of these as a type of loft conversion, you need to check whether you need planning permission and what building regulations you may have to adhere to, as this will inevitably change the overall loft conversion cost and possibly the shape you decide on.

A dormer loft conversion cost will vary greatly depending on the size, complexity, fixtures, and fittings of the proposed work, including building regulations costs that ensure the new conversion is approved. The cost of a dormer conversion can start from as little as 35K. Still, before any building begins, a professional surveyor will need to assess and then discuss your requirements in detail before providing you with an accurate quote. 

Dormer loft conversions are known for being one of the most popular styles of loft conversion because they are usually built into the existing slope of the roof and could add up to 50 cubic meters of extra room to your current home. That’s a lot!

Ceiling Height Of A Dormer Conversion?

When deciding if your home’s loft is suitable for a loft conversion, you need to consider ceiling heights – a traditional roof is 2.2 to 2.4 metres high, and for a modern trussed roof, the minimum height is between 2.4 and 2.6 metres. The levels of headroom for a habitable space is 2.3 metres. This height does not need to be upheld over the whole new loft flooring area. A lower height may be suitable for a bathroom or study if the head height is lower than the above; another way of achieving this is by lowering the floor’s ceilings underneath.

And on the Outside

It’s not just what looks good inside when you opt for a dormer loft conversion. Your kerb appeal is just as important. And how you finish the outside roof matters too. With your new dormer window(s) and choice of cladding in either slate, reinforced glass, timber, metal, or rendering, you can really create the wow factor and make your property the envy of your neighbours!

You’ll really think you have moved house.


Aim High with Your Dormer Loft Conversion

Sympathetic home improvements are a great idea significantly when they dramatically improve the appearance and layout of your property. But when it comes to loft conversions, you’ll need to ensure your planning is done by the book if you want to add value back. If it’s going to be a bathroom, it needs to be converted in accordance with building regulations because if you don’t follow the rules, you’ll effectively lose a room when you market your house.

If you do decide that you can’t face a large building project, then it might make sense to look at upgrading to a more significant property. It may also be the best solution if your property isn’t suitable in any way or if you don’t expect to stay in the property for over a couple more years. If you don’t benefit from the extension for long, then it can be hard to justify the significant financial investment and the upheaval involved while the works are taking place.

A dormer conversion can do wonders for your home. It’s not just an option; it is a necessity if you want to maximize the space in your house and make room for all of those family members who are always coming over, bringing their friends with them!
