VELUX OR ROOF LIGHT CONVERSION

The simplest and most cost efficient loft conversion of all. With significantly less construction work than other forms of loft conversion offers a way of increasing the size of your home for minimal cost.

Velux windows allow for a bright and airy loft conversion and can also incorporate rain sensors, which automatically close if rain is detected. This type of loft conversion is usually covered under permitted development.

REAR DORMER LOFT CONVERSION

A dormer style loft conversion is a way of increasing the headroom and floor space in a loft conversion by extending the roof out vertically from the existing sloping roof and will incorporate either a sloping or flat roof. Rear dormer loft conversions usually fall under permitted development and are suitable for pretty much all types of property.

MANSARD LOFT CONVERSION

Mansard Loft conversions are a type of loft conversion that is very popular with properties in London. A mansard is a roof style requiring the reconfiguration of the rear slope into a flat roof that extends from the existing ridge and slopes down at around 70 degrees, offering a maximum increase in headroom and floor space. For properties with a duel pitched roof it is possible to have ā€œLā€ shaped mansard offering even more room from a loft conversion. Mansard loft conversions almost always require planning permission due to large alterations to the existing roof structure.

HIP TO GABLE LOFT CONVERSION

Hip to gable style loft conversions require the side sloping roof known as the hip roof of a semi or detached property to be reconfigured into a gable wall with an extension of the existing ridge to form an ordinary pitched roof.

This type of loft conversion may incorporate a rear dormer or simply be turned into a Velux Room. Hip to gable loft conversions are typically covered under permitted development provided the plane of the roof on the principle elevation is not altered.

PERMITTED DEVELOPMENT EXPLAINED

A loft conversion is deemed to be permitted development, subject to the following limits and conditions:

  • A volume allowance of 40 cubic meters additional roof space for terraced houses
  • A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses
  • No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway
  • No extension to be higher than the highest part of the roof
  • Materials to be similar in appearance to the existing house
  • No verandas, balconies or raised platforms
  • Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor
  • Roof extensions not to be permitted development in designated areas
  • Roof extensions, apart from hip to gable ones, to be set back as far as practicable, at least 20cm from the original eaves.
