Dormers
A dormer is a structural element of a building that protrudes from the plane of the sloping roof surface. Dormers are used, either in original construction or as later additions, to create usable space and height within the roof. Dormers are a valuable part of the design for a loft conversion, enabling the addition of windows and balconies.
Types of Dormers
Flat roof dormer:
The roof of this dormer is flat and almost level with a frontal eave that parallels the main roof fascia. A slight fall to the top is required for rainwater drainage. They are usually large in size maximising living space within the roof.
Pitched roof dormer:
The roof of this dormer is pitched. They are always smaller than a flat roof dormer because the Apex cannot protrude above the main roof. They are usually designed for the larger roof and are mainly positioned on the front elevation.
Designing Dormers
Keeping the style consistent.
If more than one dormer is planned for each elevation then they need to be identical. If a dormer already exists then our Architectural Designer will match the style so they don’t look out of place.
Not only the style of the dormer is important but the size too. Other than the occasional larger central dormer, sizing should be consistent throughout the elevation. The massing of dormers should always be in proportion to the property so they do not overshadow the story upon they rest. For instance, a massive dormer on top of a small bungalow will look out of character. Planning restrictions/ permitted development rules will apply. Explore this page for examples of dormers, online brochures for dormer/ roof tiles and uPVC windows.
Conservation Area
If you live in a conservation area, planning permission is required for a loft conversion. It is likely your local council will not grant permission for large dormers, so a good design is essential for your loft conversion. However, they will allow you to have a recessed type of dormer which won’t be so large. A small single dormer would be suitable for a property situated in a Conservation Area or National Park. If planning permission is granted, twin dormers can also be designed to create more space and will look symmetrical. Pitched roof dormers are more favourable to the planning department as apposed to flat roof dormers.
If you have a large enough loft, our Architectural Surveyor may design your loft conversion with a combination of Velux roof windows. We have extensive knowledge in this sector with over 25 years experience with planning applications.
Examples of Dormers
Matching Dormer Tiles or Slates
Ensuring dormer tiles or slates match the existing roof material is a crucial aspect of adhering to permitted development and planning regulations. Our Architectural Designer meticulously selects materials that seamlessly blend with your roof and the surrounding environment. Explore the options available in our online brochures to find the perfect match.

UPVC Windows
Incorporating a dormer into the design offers more than just additional space; it also provides the advantage of having a conventional vertical window. We ensure continuity by matching your existing windows, and if replacements are needed, we seamlessly integrate this into the project. Our standard Eurocell white profile uPVC windows are available, with the flexibility to supply any color or style showcased in our brochures. Upon installation, we recommend referring to the Care & Maintenance brochure provided for proper upkeep.
