You CAN build a conservatory or single-storey extension without planning permission if:
- It is a maximum height of 4m high or 3m high (if within 2m of a boundary).
- The conservatory does not cover more than half the garden.
- The roof ridge or top point is not higher than the eaves of a property’s roof.
Adding a conservatory to your home can be a great way to expand your living space and create a connection between your indoor and outdoor areas. However, before you start planning your new conservatory, it’s important to understand the rules and regulations that govern their construction. One of the most important factors to consider is the size of the conservatory, as this can impact whether or not you need planning permission.
Planning permission is required for any construction that exceeds certain limits and conditions, as set out by the government. These limits and conditions include the size of the conservatory, as well as its location and appearance.
According to current regulations, a conservatory can be built without planning permission if it meets the following criteria:
- It is a single-storey structure
- It does not exceed 4 metres in height
- It does not exceed 50% of the total area of land surrounding the original house
- It does not exceed 3 metres in depth for a semi-detached house or 4 metres in depth for a detached house
- It is not located at the front of the property, unless the property is on designated land or is a listed building
Based on these guidelines, the biggest conservatory that can be built without planning permission is approximately 30 square metres for a detached house, and 15 square metres for a semi-detached house. However, it’s important to note that these are just general guidelines and may vary depending on your specific circumstances.
There are other factors that may impact your ability to build a conservatory without planning permission. For example, if your property is located in a conservation area, you may be subject to additional restrictions and regulations. Similarly, if your property is a listed building, you may need to obtain special permission before adding a conservatory.
In conclusion, the biggest conservatory that can be built without planning permission is approximately 30 square metres for a detached house, and 15 square metres for a semi-detached house.
