Understanding your planning rights and what to do with them is a specialist subject. At MSK Design we understand that a successful project demands effective planning. The planning route for any extension will depend on the type of development you are after, your property type and any planning restrictions that may be imposed on your property.
When extending your home, this may be the first time that you have had to deal with the planning process. If so, we would be happy to explain how the planning process works, and how we can assist you in addressing all of your compliance needs. We summaries a few key points to consider when identifying your planning obligations:
If you are seeking to develop under permitted development, the following must apply:
- Your property must be a single family dwelling household
- The extension cannot project further than 3m from the original rear wall of the property
- The extension cannot project to the side of the property even if it is to the rear
- A flat roof cannot exceed 3m in height
- A pitched roof will need to be hipped on both flank elevations where it is within 1m of neighbouring boundaries
- A front porch must not exceed 3m in height and have a maximum floor area of 3m2
Please note that further requirements also apply. The ones stated are generally the most common to consider which may also be subject to additional requirements.
If you are looking to extend within the following specified areas, you will need to seek full planning permission:
- Any extension that is of more than one storey,
- Any extension fronting the public highway, including side extensions and extensions behind garages,
- Any extension that projects more than 3m from the original rear wall of a property,
- Any extension that seeks to have a single pitched roof with soffit exceeding 3m within 1m of a neighbouring boundary line,
- Any works that seeks to change or increase the use of a building,
- Any extension that exceeds the limitations imposed through permitted development,
If your property is any of the following types, you will need to seek full planning permission:
- Converted property into flats,
- Purpose built flats,
- Mixed use building,
- Commercial property,
- A property not classified with C3 use,
If any of the following planning restrictions apply, you may/will need to seek full planning permission:
- Conservation area with article 4 direction (needs to be reviewed on an individual basis, as only certain parts of your permitted development may be removed)
- Listed building
- New build residential with permitted development rights removed
- For any demolition work to be carried out within a conservation area, conservation area consent will also be required in addition to any planning consent for the new build element.
- For any tree that is required to be removed or trimmed within a conservation area, planning consent will also be required.
- Any building that is to be painted in a conservation area my require consent
- Front porches that are not
In any case, we can confirm your status before we enter your home.
Many properties across the UK will benefit from ‘permitted development’. If your property is eligible, your extension will be designed within the critical dimensions permitted for its classification.
Works carried out under ‘permitted development’ are often addressed as developments that do not require planning permission however, this is only correct if all criteria listed under the General Permitted Development Order are met. For all developments carried out under ‘permitted development’, MSK Design ensures that nothing is left to chance and always obtains a ‘certificate of lawfulness’ from the local authority, to provide peace of mind for all clients. Please also note that this is now something that is often required when selling your property, which may not be until years after the works are completed.
If you are unsure of what your planning obligations are – don’t panic, we will always confirm what the status of your property is before any consultation.
