Usually required by Local Authorities on Victorian-Style properties or where clients are following the Mansard trend of similar conversions within their locality. This would be constructed at the rear of your property and has a flat roof; however, the back wall slopes inwards at an angle of 72 degrees.
Mansard lofts are normal constructed where planning permission is required or your property falls into a conservation area.

Are conversions that create a square end to the rear of the house. This creates maximum space and also creates additional headroom for the staircase and new room or rooms. If an additional en-suite bathroom is proposed along with the rooms the increased height created by the Dormer provides additional height above the fittings.

These are smaller Dormers and are usually constructed to maintain the aesthetics of your property. Planning permission is not always required

A Bonnet Dormer is an extension to a roof with a small pitched roof of its own. Local Authorities only permit full Dormers to be erected at the rear or side of a property.

This type of loft conversion is generally for semi-detached house and on the very rare occasion, end of terrace houses.
This involves changing the hipped end (sloping side) to a gable end (flat end), thus creating a much bigger loft area, generally to incorporate the new stair case to the loft.
This type of loft is normally constructed under permitted development; therefore, planning permission is not required.

Roof Light or Velux Conversion
These convert a loft area already available by fitting a flat window into the roof. It does not change the shape of the roof at all or increase the amount of space. However by using Velux Windows it does give much more light into your loft. Planning permission is not usually required.

CONSIDERATIONS
When converting a loft the following things need to be taken into consideration
- Roof - Typically changes to the roof to support either a dormer or roof lights will require an engineers design to show how the existing roof structure will support the modifications.
Floors - In general existing ceiling joists will not support an additional floor above, this may mean that additional support will be required to ensure the new space has a solid floor and wont adversely effect the rest of the structure.
-
Walls - Any new floor must be fully supported by load bearing walls. Under the party wall act of 1996 it is necessary to give notice to adjoining properties for some types of work on shared walls.
- Stairs - The new floor must have adequate access for fire and health and safety considerations. Straight flights of stairs are the preferred type if there is enough space. Spiral staircases, Ladders and alternating tread stairs can be used when space is an issue. Steps should have a tread area of at least 22cm and rise no more that cm with a pitch of no more than 42 degrees. Stair width is more flexible with no major restrictions however remember that you may want to get bulk furniture up and down the stairs. Stairs should have at least 2 meters of head room
