The dormer conversion is the most popular. This project consists of an extension of the existing roof. The extension projects vertically and results in more floor space and headroom. A horizontal ceiling caps the extension inside. These conversions work well on many styles of homes, including detached houses, semi-detached houses, terraced, and end-of-terrace homes.
These loft conversions are usually built to the rear side of the house, but it can also be built on the side or as windows dormers.
This type of extension originated with French architect Francois Mansard in the 1600s. In this design, the roof is flat, and the back wall slopes inwardly at an angle of 72 degrees. This steep angle allows for the maximization of the space available in your loft. For this type of loft conversion, you may need to get planning permission.
Hipped roofs, with their sloping sides, have limited useable space directly beneath them. Rebuilding a slanted hipped roof to one with flat-end gables opens the loft/attic area. This type of conversion changes the profile of the roof, so planning permissions are almost always required. A hip to gable loft produces satisfying under-roof space and, often, enough room for a staircase.
Adding an L-shaped dormer loft conversion is one of the best ways to increase the space and value of your property, whether you wish to extend the house for your growing family or to create some extra income. L-shaped loft conversions are a sensible and often fairly affordable way to add that extra space along with value to your property. With successful layout arrangement and beautiful design, your loft could be transformed into a comfortable living space to capture space and light.
Velux is also called a rooflight or skylight conversion. Velux is one of the most affordable extension options because no alterations are made to the roof. This also means that generally, no planning permissions are required. The main feature in this build is the addition of large windows installed flush with the roofline. Velux is a popular window manufacturer. During this type of loft conversion, Velux windows are added to allow natural light to come in, which is very important for smaller spaces like this type of loft.
Loft conversions are a great way to add value to your home. By converting your underutilized attic space into a functional living area, you can increase your property's value and add a new room to your home. This can be a cost-effective way to create additional living space without the need for a full-scale renovation.
A well-executed loft conversion by our specialists can add 10–25% to the value of your home. The increase in value can be even higher in areas where space is at a premium, such as London and other city centres.
