Loft conversions are an ideal way to increase the living area of your house, without eating into your valuable garden space. Loft conversions are a guaranteed way of increasing the value of your house by turning your unused attic into a stylish new living space.
Do I need planning permission for my loft conversion?
“Roofline” loft conversions
With this type of conversion, we would create a room/rooms within the existing shape of the roof at present using Velux windows for light and ventilation. With this type of conversion, we would not extend or alter the existing shape of the roof at present.
Normally, planning permission is not required for this type of conversion. However, a full set of Architect’s plans would be necessary along with the designs of a Structural Engineer and subsequent calculations to verify designs. This will be necessary to justify all current building regulations.
However, if your property is in a conservation area, there may be restrictions on the design and shape of the Velux windows to be installed.
“Dormer” loft conversions
Dormer’s have been referred to in many different ways, Dormer windows, Dormer extensions, roof extensions, attic extensions.
A brief description of a Dormer would be an extension of an existing roof shape. Consider a most typical terraced property/town house where the roof would start at the gutters at the front of the house rising to the Apex, the ridge in the centre of the house, then falling again down to the gutters at the back of the house. This most typical roof shape does not usually produce a substantial habitable room, unless the house is unusually large. So with this type of roof structure, it would be advisable to extend the roof and create a Dormer (usually to the rear of the property.)
The size, shape and general design of this or any other Dormer can vary greatly. This type of conversion may also not require planning permission. Householders have what is known as a permitted development allowance. This permitted development allowance is usually measured in cubic metres. The amount allowed (cubic metres) varies from property to property. Generally, the allowance would be between 50 and 70 cubic metres or 20% of the overall volume of the property.
