Planning Permission for Loft Conversions.

Planning Permission is not normally required for a Loft Conversion. It is only required if you wish to alter the roof space beyond specified limits. Party Wall agreements will need to be followed up as the dividing walls to the home are always shared unless your home is detached.

New regulation’s have recently come into force as of 1st October 2008. These state that a Loft Conversion to a home is now considered as a Permitted Development. This means that a new Loft Conversion does not require any Planning Permission if it falls within the new specified guidelines

1. For a terraced house the total area of the new dormer/s should not exceed 40 cubic metres.

2. For a semi detached or a detached property the limit is set to 50 cubic metres. This would have to include the new gable wall if you want to change a hipped/sloped roof to a gable ended/straight roof, to maximise the area as much as possible.

3. The front shape of the roof should not be changed, no dormers will now be allowed to the road side of the property unless you are developing a bungalow or a detached property. Planning Permission will need to be applied for both these types of properties.

4. If you want to add a Veranda, Raised Platform or a Balcony then you will need to apply for Planning Permission.

5. Any Windows facing to the side of the property will need to be of obscure glass and should be at least 1.7 metres above the new floor level, for safety.

6. No part of the Dormer should be any higher than the highest part of the actual existing roof height.

7. Any new materials to be used should be similar to the existing ones, this would include tiles and gutters.

8. All dormers should be set away from the eaves at least 20cm, this is not applicable for conversions of hipped/sloped to gable/straight roofs.

9. If you already have used up a few cubic metres on an Extension to the property then this will be deducted from the allowance that is allocated under the Permitted Development. Anything further will need to be discussed with an Architect or your Local Authority.

10. If you are living in a Conservation Area, Listed Building, National Park and the Broads, an area of Outstanding Beauty or a World Heritage site then you will need to apply for Planning Permission.

Planning Permission for Extensions.

The new law that came into power on the 1st of October 2008 also covers Extensions. This means that an Extension or any type of Addition to your home would fall under Permitted Development. Although there are some conditions to follow.

1. Materials used to build should be similar to that of the existing property.

2. Extension on the side of the property must be single storey extensions and should not exceed a height limit of 4 metres. The width should also be no more than half that of the original house. Double side Extensions will need Planning Permission.

4. A minimum gap of at least 7 metres has to kept from the rear boundary walls for all two storey extensions.

7. For a single storey Rear Extension the maximum depth is 3 metres for an attached property, be it a semi detached or a terraced house. For a detached property the maximum depth is 4 metres.

8. Verandas, Balconies or Raised Platforms will not be considered under Permitted Development.

9. The maximum eaves height for an extension that is built within 2 metres of a boundary wall should not exceed 3 metres.

11. Any upper floor windows that face the side of the property must be of obscure glass and also be at least 1.7 metres above the floor level.
