  • Type of roof
  • The floor below

  • Dormer loft: Dormer loft conversion extends from the slope of the roof. Flat-roof dormers are the most popular type of loft conversion. They are suitable for most houses and less expensive than.
  • Hip-to-gable loft conversion: This conversion extends the slope ‘hip’ of the roof at the side of the property and creates a vertical ‘gable’ wall creating more internal loft space. This type of conversion only works on detached or semi-detached houses.
  • Mansard loft conversion: This type of conversion runs along the whole length of the house roof altering the angle of the slope. Mansard conversions work on most properties and it is also the most expensive type of loft conversion.

Is Planning Permission Needed?
