Loft conversions have become the go-to solution for homeowners looking to upgrade and upsize their homes. And for good reason. 

They provide scope for the creation of incredible designs, spacious rooms, and beautiful spaces. The only thing left to do? Choose the best style that adds charm, value, and functionality to your home.

Types of loft conversions

Loft conversions are typically categorised into different types based on the amount of structural work involved. Some of the most popular types of loft conversions include:

Velux loft conversion 

The Velux or roof light loft conversion is easily the simplest style of loft conversion, which is both minimally disruptive and extremely cost-effective. The simplicity and uncomplicated design of a skylight loft conversion make it possible to construct without requiring planning permission.

This type of loft conversion involves the installation of roof lights (or skylights) into the pitch of the existing roof without making other major structural changes to the roof. This allows for the creation of bright, airy, and inviting rooms, be it a quiet library or study nook, or even a private and well-lit bathroom.

However, since there is no extension of the roof taking place, there must already be sufficient head height available. With the addition of floor reinforcements, insulation, and a staircase, the roof light loft conversion may cost between £20,000 to £55,000.

Dormer extension

Dormer extensions are increasingly viewed as a balanced option for a loft conversion, as they help create more headroom and floor space than a roof light conversion but are cheaper and less complex to construct when compared to a mansard.  

The dormer roof extension involves vertically extending the existing roof to create a flat-roofed or pitched roof dormer. The choice of style is largely based on the aesthetic created, while the installation of dormer windows further enhances the space and brightens the room.

Dormer extensions are suitable for almost all types of homes or architectural styles and are particularly popular in semi-detached properties that have a sloping roof. Though they may require planning permission, the versatility of dormer loft extensions (which allow for the design and creation of beautiful, bright, and airy rooms) makes this type of loft conversion incredibly popular among homeowners looking to maximise their living space.


L-shaped Dormer extension

Essentially a larger and more spacious version of the rear dormer extension, the L-shaped extension results from the combination of two dormers that are connected. This type of extension may be further customised based on the design and functionality of the loft space, as well as the structure of the extension. 

For example, an L-shaped dormer with a full width allows the maximum use of space, while an L-shaped with a balcony not only enhances the exterior appearance of the house but also creates an appealing outdoor space.

These types of dormer extensions are more suited to Victorian and Edwardian properties that may already have a rear extension and help create a great deal of added space, perfect for designing extra bedrooms, en-suites, or home offices.

These dormers do not always require planning permission if they fall under permitted developments, but it is always best to check before initiating the build. 

L-shaped dormer extensions may cost between £30,000-£60,000 but are an excellent investment as they allow for the creation of multiple additional rooms.

Hipped roof extension

Detached and semi-detached properties that feature a sloping roof are ideally suited for hipped roof loft conversions.

As this type of extension involves considerable structural work, including transforming the slope of the roof into a vertical wall, it is one of the more expensive types of loft conversions (costing upwards of £40,000) and generally requires planning permission.

Hipped roof extensions, however, add a great deal of living space, are visually appealing, and add incredible value to the property. Therefore, they are considered to be well worth the initial investment.

Double Mansard

Particularly suited to period properties, including terraced, detached, and semi-detached homes, a double mansard is the most extensive type of loft conversion.

It involves creating a mansard roof by altering the slope of the roof to an angle of 72 degrees at the front and rear of the house, essentially creating an entirely new storey. Though this invariably requires planning permission and is expensive to construct, these extensions have a dramatic effect on the space within.

With the extensive space made available, a double mansard may be used to create multiple rooms, including one or two bedrooms and en-suites. All of which have a significant impact on the overall value of the property.

Innovative ideas for your loft space

With numerous design options available, transforming your loft space into a functional room essentially involves balancing the size of the room with your needs and unique aesthetic. Some of the best ideas for a loft conversion include:

  • A master bedroom

Create the bedroom of your dreams with a beautifully furnished, luxurious master suite that encompasses an en-suite bathroom and even a walk-in closet.  Skylights or dormer windows help bring in an abundance of natural light, while soothing colours create the perfect place to relax after a long day. 

  • Home office

The loft space is perfect for creating a functional home office that is far away from the bustle and noise of the downstairs area. Built-in desks, customised storage, and proper lighting help create a comfortable and productive workspace. 

  • Guest suite

Create the ultimate haven for your guests with a comfortable guest bedroom that offers privacy and tranquillity. Optimise the layout to make the most of the available space while utilising the awkward corners for creative storage solutions to provide guests with ample storage space. 

  • Playroom

The loft space typically inspires imagination and playfulness, making it the perfect space to build a fun and vibrant play area for kids, complete with storage for toys and games. Consider the installation of safety features and durable flooring to help design a safe space for young minds to independently learn and explore.

  • Home Library

A cosy reading nook works even in the smallest of spaces. Built-in bookshelves (ideally utilising the loft’s height), comfortable seating, and soft lighting allow you to design a tranquil reading space for avid book lovers. 

Your loft space is so much more than an additional storage area. It holds the potential to completely transform the style, space, and value of your home. From an elegant bedroom and cosy library to an efficient home office and an engaging gaming area, loft conversions add so much to a home. All that is required? A brilliant idea, a functional design, and a team of experts to lead the way.
