3 Reasons Why You Should Build a Dormer Loft Conversion

If you want to expand your loft and turn it into living space, one of your options is to build a dormer loft conversion. This is a really popular style of loft conversion and definitely the most common.

Read on to find out more about dormer loft conversions and their benefits.

What’s a dormer loft conversion?

A dormer loft conversion is when you build onto the back, side or even front of your roof to create more internal space. Dormer extensions have vertical walls, which echo the angle of your exterior house walls and contrast with the angle of your pitched roof. Most dormer extensions have flat roofs, but you can fit a pitched roof on yours if you prefer. Dormer extensions vary in length, from the width of a window to almost the full length of your roof.

What are the benefits of building a dormer loft conversion?

Dormer loft conversions have many benefits that can make them a great addition to your home.

Lots of headroom

Lots of people choose to build a dormer loft conversion because of the good amount of headroom they offer. Instead of having to stoop under a sloped ceiling, a dormer will increase your loft ceiling height so you can maximise your space.

Increased natural light

Building a dormer loft extension can be a great way to let more natural light into your home. It increases the exterior surface area of your loft, which means you have more places to fit windows and let light in. Increasing the amount of natural light you have in your loft will not only make it feel bigger, it’ll also make it more enjoyable to spend time in.


Another benefit to dormer loft conversions is that they’re versatile. The space that they create can be used for almost anything – a master bedroom and ensuite, playroom or office. The increased height that dormer extensions offer mean that you can fit things like showers and tall cupboards in them, which would be harder in other types of loft conversion.

So a dormer loft conversion is well worth considering if you want to turn your loft into a useful, comfortable living space. To find out about your other options, see our articles on hip to gable and mansard loft conversions.
