Dormer windows have always been a popular part of the house. After all, they enrich the look immensely and provide some sophistication behind the architecture. At the same time, they also have an effect on the interior of the house and quickly make the room more comfortable. Small and narrow-looking rooms in particular are suddenly flooded with light and loosened up. For example, a storage room quickly becomes a cozy space to retreat to. However, there are numerous types of dormers, which differ in design and function. So there should be enough know-how about the various options before planning.

All kinds of dormers: there are

The purpose of different dormers is mostly the same. They should also give the converted attic access to daylight. At the same time, more living space can be created by installing a dormer. The dormer is planned when the new building is built. However, in order for the end result to be convincing in every respect, even the planning should be well prepared. The following options are possible in connection with the dormer window.

Gable and triangular dormers

The gable dormer, also known as the triangular dormer, is one of the classic forms of the dormer in domestic buildings. It takes its name from the fact that its roof forms a triangle and thus says for a bit of avant-garde as well as for an angular design in architecture. The structure can be imagined in such a way that two elements are leaned against each other and as a result the typical triangular shape is created. Despite its classic reputation, the triangular dormer can also be found in modern households. After all, it enhances the look and ensures sunlight in the attic. In addition, the triangular dormer impresses with its comparatively slim design, which means that it can be attached to a building several times without being too bulky. You can easily add it to a large window or two small windows.

Drag and flat roof dormers

The flat roof dormer proves that modern and innovative do not always have to be equally complicated. Instead, it is one of the simplest types that can be installed in the roof and thus in the building without any problems. Because this is basically a window that is attached to a square dormer, the flat or gable roof. With the flat roof dormer, you not only create a dormer yourself, but also add additional living space. Because various sloping ceilings are broken up here, making the room appear larger and, above all, brighter. The flat roof dormer also has a positive effect on the look from outside. Because here it ensures modern aesthetics. However, it is important that this type of dormer actually matches the construction itself. Because while other types can easily be combined afterwards, the look of the flat roof dormer must very well fit into the concept. It is therefore advisable to factor in the flat roof dormer when you first build and plan your new dream home. It enables completely new options in the attic area. It can be equipped with a pivoting window or a balcony, so that the top floor can be used at all lengths.

Trapezoidal dormers

The trapezoidal dormer also lives up to its name. So the dormer is a trapeze here. However, since this is a monumental framework, the trapezoidal dormer is primarily suitable for larger houses. In small buildings, it can quickly appear overwhelming and thus affect the appearance. As a result, it can be integrated even more beautifully into the existing roof. Because the same material as the roof itself can be used for the covering material. So the trapezoidal dormer does not attract attention, but instead harmonizes with the entire concept. At the same time, this enables the trapezoidal dormer to be integrated into the existing building afterwards. The change is therefore not fatal, which is why the trapezoidal dormer also makes sense if space is to be created for solar panels. Ultimately, of course, a dormer in this form not only influences the external appearance of the building. Much more, it also creates interesting effects in the interior and ensures that the room is upgraded in every respect. Because the course of the room height is influenced by the geometric shape of the trapezoid, which means that the interior appears wider and more avant-garde. As a result, this is worthwhile in terms of appearance and use, but of course it also has its price.

Dormer windows

One could think that the pointed dormer is a triangular dormer in the broadest sense. In fact, this type of dormer is really a triangle. However, it is the case that the angle is smaller and thus the shape, according to the name, is more acute. This type of dormer therefore provides interesting details in the exterior view, but of course also offers less space for windows. Anyone who wants to guarantee the highest level of light incidence in the attic is not advised with the pointed dormer. Instead, this is particularly worthwhile for smaller houses. Here it is often worthwhile instead of the triangular dormer, as its appearance looks narrower and less conspicuous. Despite the smaller area for windows, this of course guarantees more light incidence than would be the case without the dormer.

Hip and half-hip dormers

The hipped dormer and the so-called saddle roof dormer can be confused from a visual point of view. However, the structure differs through distinctive properties. Then, while the two look alike, the hipped dormer is formed from all sides when viewed more closely. In this sense, the hipped dormer is created from above as well as from below and the sides. This in turn means that the hipped dormer is particularly harmoniously integrated into every building. So it doesn’t just stand out, but completes the whole picture. The area created by this type of dormer can be used generously for various windows. But of course the multifunctionality and aesthetics of this type of dormer also have a proud price. High costs are to be expected.

Round dormers

There are different types of round dormers, with a distinction mainly being made between segment arch and clay roof dormers. The segment arched dormers have a circular section which rests on the dormer cheeks. As a result, it is very flexible when it comes to varying the roof height. This type of dormer can also be designed in such a way that a lot of light in particular flows into the attic. The clay roof dormer, in turn, only has a semicircle, which has a seamless transition to the rest of the roof. This creates a harmonious picture.

Bat and ox-eye dormers.

The bat dormers, which are also known as ox-eye dormers, can be found particularly in North Frisia or on thatched roofs. The name can be found in the section of a circle, which is carried out within the dormer. This increases the swing of the dormer, which in turn resembles the look of an ox-eye or a bat. Several bat dormers can be attached to a single roof. The fact that they connect directly to the roof creates a particularly harmonious image. While very large windows can be used depending on the size of the dormer, nothing is added to the living space. Because this type of dormer is just a change to the roof.

Does the dormer construction require a permit?

All of the above-mentioned dormers can be easily implemented with installation kits. However, this does not change the fact that the building authorities intend to be involved in this project. Because building a dormer changes the statics of a house significantly. It is therefore necessary that an expert, namely the structural engineer, is involved in the planning. Especially when it comes to adding a dormer, for example to an old house, the effects can be serious without the correct calculation. However, once the structural engineer has prepared a professional plan, this only needs to be approved by the building authorities and, as a result, the client can have it carried out.

Costs for the dormer construction

The cost of building a dormer depends largely on the model chosen and the size. Not only the price for the dormer itself should be calculated. Then there is also the installation of windows or any other components.

At the same time, it must also be taken into account whether it is a prefabricated dormer or an individual model. For finished products, around 5,000 euros can be expected. Of course, this is multiplied by the number of dormer windows. However, lower prices can also be expected by choosing the right material.

If the dormer is not a finished model and is instead to be set up individually, the costs can even double and triple. Independently of this, the costs for the roof connection, the roofing and the covering are also added. All in all, a single dormer often costs 10,000 euros.

Make a dormer yourself?

Even talented craftsmen cannot mount the dormer on the roof. The work of experts is always required here in order to achieve high-quality and, above all, safe results.
