Thinking about adding to your living space with a loft extension? If you’ve got unused loft space, there are various approaches that you can take to repurpose it, depending on the space available. It can become a space that you can make use of, and it’ll also add significant extra value to your property.

We’ve created profiles for 5 of the most common types of loft extensions, giving you some initial inspiration for your own project. Understand each kind of loft extension, then take a look at how we’ve installed them in our projects.

Dormer loft extension

A dormer loft extension is one of the most popular choices, and it involves adding a box-like structure to the existing roof to create additional headroom and floor space. This kind of loft extension has the most potential to become an entirely new room in your home, so if you’ve always dreamed of creating a master suite in your loft, this could be the perfect solution. This design allows you to increase the natural light that flows through the space by adding skylights, and it could even accommodate a balcony.

Depending on the extent of the changes that your dormer loft will warrant, you may require planning permission for this kind of extension. It’s also worth noting that a dormer loft extension can change the exterior appearance of your home - we’d recommend working with an interior architect to understand this.

How long does it take to complete a dormer loft extension?

Dormer loft extensions can take anywhere between 4-6 weeks to complete - though this can vary based on the individual property and contractor.

Velux loft conversion

A Velux loft extension involves adding windows to the existing roof slope, without changing its shape. Velux is the brand of window that tends to be fitted into these types of loft extensions, as their design lends themselves to this structure. Velux loft extensions are an extremely cost-effective choice, and they’re a prime choice for those who may already have a sloping loft structure, but it’s either not in use or it lacks natural light.

You won’t have the same headroom that a dormer loft extension provides, and you’ll also have noticeably less floor space. This kind of loft extension focuses more on enhancing your current space, rather than adding new space.

How long does it take to complete a Velux loft extension?

Velux loft conversions boast a quick turnaround timeframe from installation to completion, the only factor to account for will be replastering and painting the surrounding walls if required.

Hip-to-gable loft conversion

A hip to gable loft extension is: Ideal for houses with hipped roofs, as this kind of conversion extends the roof by replacing the sloping side (hip) with a vertical wall (gable). If you’re looking to create as much loft space as possible, this could be an ideal choice. However, planning permission might be necessary, and due to the structural changes involved, it can be costlier than other types of loft conversions.

How long does it take to complete a hip-to-gable loft extension?

As considerable structural changes are involved, hip-to-gable loft conversions can take a longer time to complete, with the average time being around 8-12 weeks.

Mansard loft conversion

Named after the 17th-century French architect, Francois Mansard, this type of conversion involves extending the roof with a flat roof and a steeply sloping side. If you’re eager to create a space that you can enjoy, then a Mansard loft extension will give you plenty of interior design flexibility. It’s an effective approach if the main objective of your loft conversion is to add a usable living space to your home. This is another kind of loft conversion that might require planning permission, but the investment is certainly worthwhile in the long-run.

How long does it take to complete a mansard loft extension?

Mansard loft extensions require the most significant structural amends, as the process involves replacing the entire length of the roof with a flat wall. Depending on your contractor, you could expect your Mansard loft extension to be completed in 12 weeks.

Modular loft extension

A modular loft extension involves adding pre-built units that are constructed off-site and then installed onto the existing roof. It tends to be a fast installation process, with minimal disruption and downtime for your home during construction. Despite this, you’ll still be able to enjoy a high-quality finish. The caveat of this style of loft conversion is that they are slightly limited in terms of customisation possibilities, and they aren’t a suitable option for every home.

How long does it take to complete a modular extension?

As we’ve mentioned, modular extensions are an efficient way to maximise your space, with an average installation time of 2-3 days.

How do I choose the right type of loft conversion?

The best and most realistic starting point for choosing the right kind of loft extension for your home is to understand the space you have, and to think about how you’d ideally like to enhance it. Of course, some kinds of extensions have certain constraints based on your space, and our experts will help you to understand the choices available to you on this basis.

It’s no surprise that budget comes into play here too, but it’s always worthwhile considering the longevity that the changes will offer - from giving you more usable space, to increasing the market value of your home.
