Do you want to add space in your home with minimal hassle? On occasion, it is important to know what size home extension you can build without any planning permission. Experts can guide you through the process. Understanding the permitted development(PD) can assist in optimising the space without unnecessary delays. If you are under the permitted development guidelines, then a home extension in Solihull is possible without formal planning approval. However, it is necessary to meet the criteria.
Home Extensions Without Planning Permission
Rear Extensions
If it is a terraced or semi-detached home, you are allowed to extend up to 3 metres in addition to the existing rear wall. In the case of the detached home, up to four metres of expansion is acceptable. It is a limit that is set for the single-storey rear extensions based on the standard PD rights. Previously, the limits have been 6 metres for the terrace and semi-detached home. On the other hand, a detached home could have been extended to 8 metres. However, these rules have changed as of May 2025. When it is a large extension, it may be necessary to get Neighbourhood Consultation. Councils usually notify the neighbours to know whether they have any objections. Still, it is a simple method in comparison to full planning.
For a single-storey rear extension, the height up to which you can extend is 4 metres overall. Expansion within 2 metres of the boundary may have an optimum eaves height of about 3 metres.
Conservatory and Garden Rooms
Experts can build a conservatory without any planning permission. On occasion, there are similar rules to the ground floor extension. While making plans, it is better to concentrate on how you can optimise your present space. A clear idea about the purpose of the space can help you plan a better way.
A proper understanding of the extension may be able to add value to the property further. Whether it is a conservatory or garden room, you can utilise it for dining or cooking.
Side Extension
Under the permitted development, it is possible to build a side extension for a single storey. On occasion, you can easily go up to 4 metres. However, the width should not be more than half of the original width of the present home. The original home needs to be present at the location from 1 July 1948. If the property is located in a National Park or Conservation Area, there may be more restrictions.
Maisonettes and flats may not be able to take advantage of the PD rights. Listed buildings also need listed building consent for any type of home extensions.
Thanks to the PD rules, homeowners can enjoy some flexibility. However, it is always better to ensure that you are compliant with the governmental rules and regulations. It may help forget about the expensive enforcement notices.
