Do I need Planning permission?
Building a conservatory is a fantastic way to create space and light within your home, whilst making a connection with your outdoor space and increasing the value of your property. The trouble is, many homeowners are put off by the thought of having a Conservatory built, often out of confusion surrounding the rules. New regulations came into effect in 2008 which give homeowners the right to build a Conservatory under 'permitted development rights'. This means that you do not need to seek planning permission. However, as with all permitted development, there are certain limitations and exceptions. We recommend that you always check with our own Independent Planning Specialist who can ascertain exactly what is or isn’t required for your own property. Generally, building a conservatory under permitted development is subject to certain conditions. These are as follows:
No more than half the area of land around the original house will be covered.
A Conservatory will not extend forward of the fronting highway, (often known as the “Building Line”)
Conservatories must not be higher than the home’s roof and only a maximum of four metres high.
Single storey rear Conservatories must not extend beyond the rear wall of a house by more than three metres if the house is attached, or by four metres if it's detached.
Two storey Conservatories must not extend beyond the rear wall of the original house by more than three metres or be within seven metres of any boundary opposite the rear wall of the house.
The house is not in a conservation area, national park or designated Area of Outstanding Natural Beauty. If it is any of these it will require planning permission.
These are only the main points and as with all Government regulations often there are more complicated exceptions and rules. It is always best to get professional help to ascertain what your rights actually are and to get confirmation whether planning is required or not. There are other limitations that also apply to Conservatories and for more in depth information on Conservatory Planning Permission, please visit the Government website at The Planning Portal-planning applications
Planning permission and building regulations are often confused. "Planning permission is concerned with the visual impact and size of the structure and not the technical integrity." Building regulations, on the other hand, covers all aspects of building construction and are constantly being reviewed. Building regulations are statutory instruments that seek to ensure that the policies set out in the relevant legislation are carried out. Building regulations approval is required for most building work in the UK, however a Conservatory is usually exempt from building regulations provided it is:
Built on to a domestic dwelling and divided from the rest of the house by a door that complies with the requirements for an exterior door.
Under 30m sq in floor area.
A single storey.
Built at ground floor level.
Glazed in compliance with safety glazing requirements of approved Document N of the Building Regulations BS6262 Part 4
Not built within 1m of the boundary.
Fitted with a roof that is 75% glazed and with walls that are 50% glazed.
There are other limitations that apply to buildings constructed as Glass Room Extensions and for more in depth information on building regulations, please visit the Government website at The Planning-Development Building-Regulations.
Listed Buildings have been an area of expertise for Room Outside having built many hundreds of Timber Hardwood Conservatories and Orangeries onto properties throughout the South. These require close attention to detail with regards to planning and Listed Building Consent.
In almost all situations, you are likely to need Listed Building Consent to build a Conservatory onto a listed building. Listed Building Consent is granted by your council. It is vital to consult with your Local Planning Authority to decide the best course of action. Remember that building a Conservatory without permission onto a listed building is a criminal offence. Permission is also required to replace an existing structure.
