What is dormer loft conversion?

  The dormer loft conversion is to add a box structure to the pitched roof, creating walls at a 90-degree angle to the floor. Dormer loft conversion is one of the most common types of conversion in the UK, very suitable for semi-detached or row houses in built-up areas. The dormer extends upwards and outwards to provide additional headroom and floor space.

Types of dormer loft conversion

  Dormers come in various shapes, styles and sizes. Make your dormer extension design correct, it can enhance the appearance of your home and increase its curb appeal; get it wrong, it will be an eye-catcher. The challenge is to maximize the internal space while ensuring that the dormer is proportional to the existing house.

  The main dormer types are:

  Gable or dog house dormer: they are characterized by the sloping roof with two sloping sides, forming a triangle below the roof line, just like a classic dog house. Small single gables are usually built to increase light and visual appeal, while larger gables also provide additional space.

  Hip roof dormer: these are similar to gable roof dormers, but with three sloped sides instead of two. It provides more horizontal space than gable dormers and more overhead space than shed dormers.

  Shed dormer: on these, the slope of the roof is the same as the main roof, but the slope is much smaller. It has no peaks or hips, thereby reducing costs. These dormers are usually installed to create more space, so they can be large.

  Flat roof dormer:they have a box-like structure with a flat roof and are usually built behind the house. These provide the maximum internal space and head height, because all the walls are vertical, but it looks a bit awkward, like someone posted a box on the side of the house.

  Duplex dormer: named after French architect Francois Mansard. This is also usually built at the back of the property, with the central flat roof and the vertical sides usually at a 70 degree angle. These extensions provide a significant increase in loft space.

  L-shaped type: this involves the construction of two dormers-one on the roof of the main house and the second above the rear extension. The two dormers meet to form an L shape. It is very popular among owners of Victorian terraces.
