Looking to add space, value, and functionality to your home without moving? At Build the Fast, we offer professional loft conversion services across the UK, transforming unused attic space into beautiful, practical living areas. Whether you need an extra bedroom, home office, en-suite bathroom, or creative studio, our team delivers high-quality conversions tailored to your needs—quickly and efficiently. Loft conversions are one of the most cost-effective ways to increase your home’s living space and resale value. We provide end-to-end services, including design, planning permissions (if required), and expert construction.
We specialise in a variety of loft conversion styles to suit different property types, preferences, and planning constraints:
Add Headroom and Space with Style
Dormer conversions are one of the most popular loft conversion types in the UK. This involves extending the existing roof vertically to create a flat-roofed box shape that provides more floor space and headroom.
Dormers are ideal for semi-detached, detached, and terraced homes and often allow for the installation of full-size windows. They’re perfect for creating spacious bedrooms or bathrooms and are usually permitted under permitted development rights.
Elegant and Spacious, Ideal for Urban Homes
Mansard conversions are typically built at the rear of the property and involve raising the party wall (the shared wall between you and your neighbours) and creating a flat roof with a slight slope. This style provides maximum internal space and gives a more traditional feel, blending well with period properties, especially in cities like London.
Due to the significant structural changes involved, planning permission is usually required, but the results are striking and spacious.
Brighten Your Loft Without Changing the Roofline
If you’re looking for a more affordable and less invasive option, a Velux loft conversion (also known as a rooflight conversion) may be the right choice. This method keeps the roof structure intact and simply adds Velux windows to allow natural light into the newly created space.
Ideal for properties with enough existing headroom, this type of conversion is quick to complete, cost-effective, and often doesn’t require planning permission.
Enjoy Outdoor Living with a View
A roof terrace loft conversion adds more than just interior space—it provides access to a stunning private outdoor area. These conversions are often paired with dormers or mansards, allowing you to step out onto a terrace built above a flat roof extension or rear outrigger.
Roof terraces are perfect for homeowners in cities or those with limited garden space. They offer a fantastic lifestyle upgrade, ideal for morning coffee, evening relaxation, or entertaining guests, right at the top of your home.
