What are the different types of loft conversions?

In the United Kingdom, there are five primary attic conversion styles that are commonly employed to add space. The type of loft conversion you choose should be determined by your current roof structure, as well as how much money you want to spend and when necessary, planning limitations.

Arrange a site visit and we will be able to advise what your options are.

Full Rear Dormer Loft Conversions

A full rear dormer conversion is a great way to add additional room and create a spacious, versatile space. By projecting out vertically from the sloping section of the roof, this style uses standard windows to let in natural light and fresh air. You can choose to have a dormer that spans the entire width of the roof or opt for a couple of smaller dormer windows spaced at regular intervals. With its box-like structure, this loft style is perfect for anyone looking for a practical and stylish space that’s easy to use.
Most importantly, it is suitable for most UK house styles.

Pitched Roof Dormer

A pitched roof dormer conversion lends itself to large footprints or high-pitched roofs. It is sometimes a requirement instead of a full rear dormer, especially if you reside in a conservation area.
In addition, it makes an attractive feature. You can add various pitched roof dormers depending on your property. A dormer on the front of a property requires planning permission. However, you can add them at the rear under permitted developments in many cases.

L-Shaped Dormer Loft Conversion

An L-Shaped loft conversion entails the construction of two dormers that connect together. The L-shaped form is generally attributed to one dormer being constructed on the rear outrigger roof and the other on the main roof, giving it an immediately recognizable L shape.

The L-shaped dormer’s shape limits its usage to specific sorts of property, such as Edwardian or Victorian houses with an existing outrigger at the rear. This style is excellent for gaining more space area in a property like this since you own a mid-terrace house.

The majority of L-shaped attic loft conversions are covered by permitted development rights, so you won’t need planning permission. There are some exceptions: if the home is in a conservation area or a designated landmark, for example, you will have to submit an application.

Roof Light Loft Conversion (Velux)

A roof light loft conversion, often referred to as VELUX loft conversions since the window brand is so associated with roof windows, are turning a roof area into a loft. Other types of loft conversion involve altering the structural framework of a roof; whereas a roof light Loft Conversion attempts to make use of what exists rather than replacing it.

The cost of Velux loft conversions is also likely to be kept low since there will be no huge changes to the roof, which is another reason they are becoming more popular.

Rooflight attic loft conversions allow you to conceal the roof lights from view while keeping their functionality, which means your home’s appearance and functionality aren’t substantially altered.

Hip-to-Gable Loft Conversion

The majority of hip-to-gable loft conversions are done on semi-detached houses with an existing hipped roof. The hip is extended vertically from the ridgeline to create a gable, and a rear dormer is built to the rear of the home.

This is one of the most popular types of loft conversion because it maximizes floor area and head height.

The biggest advantage of a hip-to-gable loft conversion is that it significantly increases the floor space and headroom in your house. This may provide you with an additional bedroom and bathroom, making your home considerably larger.

Hip-to-gable loft conversions can require planning permission due to the size so book for a free consultation and we will advise you.

Mansard Loft Conversion

The term “Mansard” is derived from the French architect Francois Mansart (1603–1666). A mansard loft conversion is made of a similar external form to the rear dormer, with a flat roof and a sloping face. The Mansard’s face is sloped by 70 degrees. Bricks are commonly used to build the sides of a Mansard, although they may also be tiled.

The roof is flat and windows are typically housed within small dormers.

In comparison to a Dormer loft conversion, a Mansard has slightly reduced head height and floor area due to the face’s 70-degree slope.

Frequently asked questions

According to RESI, a UK homeowner can add up to £100,000 + to their home value by converting their attic, assuming they open up 24m² of new space in their property. However, this value tends to vary across properties and different localities.

You may use this free program to estimate the worth of your extension based on your property sizes and location. Finally, you can make an initial approximation of the value that the conversion will provide to your home.

Typically, you can expect to spend between £10,000 and £45,000 on a loft conversion in London. The final loft conversion cost will depend on the size and complexity of the conversion, as well as the materials and labour costs in your area. An experienced loft conversion company will typically charge more than smaller, local companies, but you can be assured the quality of the work will be superior.

On average, a loft conversion will take between 4 and 8 weeks. However, this will depend on the size and intricacy of the conversion project. Smaller projects with fewer changes to the structure of the home will be completed more quickly, while larger or more complex loft conversions may take longer.

We will provide you with a timeline as part of your free no-obligation quote.

Some people choose to use an architect for their loft conversion, while others do not. It really depends on the complexity of the project and your own personal preference. Architects can be helpful in designing a conversion that is both aesthetically pleasing and functional.

For your loft conversion, you do not need permission from your neighbours or a Planning Permission from your council (as loft conversions are usually considered “Permitted Development,” but if the project is in a terraced or semi-detached property, you may need to have a Party Wall Agreement).
