Planning permission for loft conversions

Planning permission is not normally required. However, permission is required where you extend or alter the roof space and it exceeds specified limits and conditions.

Under new regulations that came into effect from 1 October 2008 a loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:

• A volume allowance of 40 cubic metres 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 eaves

*Bear in mind that any previous roof space additions must be included within the volume allowances listed above.
**Planning permission may be required if your property is in designated areas include national parks and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.

Loft Conversion transformed into a master bedroom with en-suite bathroom in Sheffield

We are now 6 weeks into the fantastic loft conversion in Fulwood, Sheffield. We have constructed a double story extension to the side of the property and taken the new roof line through to match the existing roof.

We have designed the loft with a rear dormer window to maximize the floor space within the new loft bedroom and bathroom.

The new staircase has been fitted along with 5 M08 top opening Velux windows.

We are now constructing the new stud walls and insulating the rooms to comply with building regulations. We will be posting more images of this huge conversion over the next few weeks.

Loft conversion building regulations

Building regulations will always be required if the loft space is being converted into any usable form of accommodation or habitable room. These requirements are in place to ensure that the necessary construction criteria are met and that the all health and safety laws, amongst other things, have been satisfied. We apply and obtain building regulations on all our loft conversions and garage conversions, so you don’t have to.
