What Is A Dormer?
Dormers are built-in structures of either wood or brick that are designed to add additional space and head height to a loft conversion. This kind of loft conversion happens when the loft height is limited, or when you’d like to maximize the space in the loft for a purpose other than adding another storey, for example, if you’d like to create a comfortable home office without adding another storey.
What Is A Dormer Window?
But what is a dormer window? Dormers are vertical windows that have their roof. They are protruding from a pitched roof and usually have horizontal and vertical planes. The view from a skylight is better than a skylight since it offers views outside just like a conventional window and creates a greater sense of space. As with skylights, dormer windows allow light into the roof space or loft, but unlike skylights, they also allow more headroom to be utilized and allow the space to be used for other purposes. Dormers can be categorised in many different ways, with the roof type determining which kind of dormer they are.
Types Of Dormer Windows
Dormers on a wall are structures whose vertical transverse plane shares the horizontal transverse plane of the wall. The gable end of a wall is incorporated into the structure of the building, doing away with the eaves. They don’t add much aesthetic value to a house since they aren’t common dormer types. The bigger windows on modern homes also allow for lots of natural light to enter inside. The larger windows are in essence extensions of the wall to the roof. It is because of this that they are seen as a wall element on the roof that appears vertically extending rather than being part of a wall.
The wall dormer is typically associated with older buildings and is usually smaller than the main course. Since they are belonging to the eclectic assemblies of these structures, they are an important part of the style itself.
Barrel Roof Dormer
Another type of dormer windows in London is a barrel or arched roof dormer window. It’s easy to identify the dormer’s rounded or arched top by observing that each side and the front of the dormer have some wall space left. By adding this soft touch of colour, one can put some soft contrast against mostly harsh, straight lines that are seen on most sloped roofs. Due to the way that it separates the roof from the structure below, it is also known as a segmental roof dormer. It is more usual to build barrel roof dormers for aesthetic purposes as opposed to any specific use or function that they might have. As a result of the large size of their windows, they let in a lot of light, but their size makes them smaller than most other types of dormers. Since they are an uncommon type of dormer, you cannot just build them on top of a gable or a flat roof, so they will be more expensive to build.
A shed dormer, a large dormer window is a type of dormer with only one roof plane and a much shallower pitch than the slope of the main roof. Sometimes, when reassembling a shed dormer, the pitch is so slight that it almost looks like it is horizontal. Water must run off the dormer to prevent it from catching on its roof.
Its roof design differs from a flat dormer roof by having a gently curved surface that extends completely above the window, instead of a flat surface. In contrast, the eyebrow dormer has no additional walls on either side. This can give the impression that the eye is peeking out from underneath the hooded outer eyelid.

Planning Permission To Add Dormer Windows

It must be noted that to stay within PD requirements, no part of the dormer has to exceed the top of the existing roof. As well, the dormer cannot project more than 15 centimetres forward from an existing roof slope facing a roadway or an elevation on a side of the house.
As planning authorities vary, it’s necessary to fully understand whether you need planning approval for proposed alterations. Any type and size of dormer windows you wish to install on a listed building or in a conservation area will require planning permission.
