“Will I Need Planning Permission For A Bristol Loft Conversion?”

(basement conversions planning permission notes below underneath)

Many loft conversions will not require planning permission as they fall within the bounds of what is known as “Permitted Development”, however permitted development has it’s limitations.

Limitations Of Permitted Development For Loft Conversions

**As quoted From The Planning Permissions Official Webpage

  • 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 original eaves
  • The roof enlargement cannot overhang the outer face of the wall of the original house.

Some of the above information will likely be ambiguous to you in relation to your specific loft conversion project, don’t worry, our specialist builders will likely be able to give insight into how these rules and regulations apply to your Bristol loft conversion

Planning Permissions For Basement Conversions

“Will I Need Planning Permissions For My Bristol Basement Conversion?”

Many basement conversions are within the bounds of permitted development, meaning that many basement conversions don’t require planning permission, however if structural changes are required, planning permission may be required also, direct quote from the planning permission official website:

Converting an existing residential cellar or basement into a living space is in most cases unlikely to require planning permission as long as it is not a separate unit or unless the usage is significantly changed or a light well is added, which alters the external appearance of the property.

Excavating to create a new basement which involves major works, a new separate unit of accommodation and/or alters the external appearance of the house, such as adding a light well, is likely to require planning permission.”

Again, with matters of planning permission and how this applies to your project, once you meet with our expert specialists/ builders you will be given insight into how the rules apply to your project and what will be required (if anything).
