Loft Conversion Types

There are 4 main types of loft conversion; Velux/Roofline, Dormer/Kennel, Hip to Gable/Gable End, and Mansard conversions.

Velux

Velux conversions are the most common, and give you the classic loft conversion room with the sloping ceiling that follows the roofline. These conversions are typically fitted with Velux windows and are the fastest and cheapest to build.

The pros:

  • Fast
  • Cheap
  • May not need planning permission to build
  • Easier to gain planning permission if needed
  • Privacy (due to windows facing upwards)
  • No extensive changes to the outside of the home

The Cons:

  • Sloped ceiling
  • Smaller internal space

Dormer

Dormer or Kennel loft conversions are similar to Velux conversions, but add boxes to the roof so that you gain additional headspace and your windows face outwards rather than upwards (like a Velux conversion).

The pros:

  • Still fairly fast to build
  • Still relatively cheap
  • More headroom
  • May not need planning permission to build
  • Relatively easy to gain planning permission
  • Dormers can be built to suit the rest of your home

The cons:

  • Longer to build than a Velux conversion
  • May not be allowed on listed buildings or in conservation areas
  • Not significantly more headroom
  • Less privacy

Hip to Gable

Hip to Gable, or Gable End conversions involve making significant changes to the roof. A hipped roof is one where the ends slope inwards and a Gable End is where the ends go straight up, following the existing line of the walls. Changing the ends of the roof provides more headroom and usable space within the loft.

The pros:

  • More headroom
  • More usable room
  • Blends into most house styles fairly easily
  • Materials can be used so that the change is imperceptible after it’s built

The cons:

  • Planning permission is required most of the time
  • Takes longer to build
  • Most expensive

Mansard

Mansard loft conversions make the most extreme changes to both the interior and exterior of the house. A mansard is almost like a huge dormer, which turns the roof shape from a triangle into a rectangle so that the interior rooms look and feel more like normal rooms rather than a loft conversion. Double mansards are also possible, where both sides of the roof are opened up

The pros:

  • Maximum headroom
  • Maximum usable space
  • Interior feels like normal rooms
  • Materials can be used so that the change is more subtle after it’s built

The cons:

  • Most expensive type
  • The longest to build
  • Requires planning permission (which may not always be granted)
