Greenhouses are a popular addition to many UK gardens, offering a controlled environment to grow plants, fruits, and vegetables year-round. However, before you start constructing your greenhouse, it’s essential to understand whether you need planning permission. In the UK, planning regulations can vary depending on your location, the size of the greenhouse, and how it will be used. This blog post will guide you through the key considerations.
Understanding Permitted Development Rights for Greenhouses
In the UK, many homeowners benefit from Permitted Development Rights (PDR), which allow certain types of construction without needing formal planning permission. Greenhouses often fall under these rights, particularly if they are considered an “outbuilding.” However, there are specific criteria your greenhouse must meet to qualify:
• Size and Height: The greenhouse should not exceed a height of 4 metres if it has a dual-pitched roof, or 3 metres for other types of roofs. If it’s within 2 metres of a boundary, the maximum height allowed is 2.5 metres.
• Location: The greenhouse must be located in the rear garden or backyard. Structures built in front of the house usually require planning permission.
• Coverage: The greenhouse and any other outbuildings should not cover more than 50% of the total area around the house.
• Design: The structure must be single-storey with no balconies, verandas, or raised platforms.
If your greenhouse meets these criteria, it is likely you won’t need planning permission. However, there are exceptions, especially if your property is located in a designated area.
The Purpose of the Greenhouse
The intended use of the greenhouse can also affect whether planning permission is required. If the greenhouse is for domestic use (e.g., growing plants for personal enjoyment), it is more likely to fall under Permitted Development Rights. However, if you plan to use the greenhouse for commercial purposes, such as selling plants or hosting events, you may need to apply for planning permission.
Temporary vs. Permanent Structures
Another consideration is whether the greenhouse will be a temporary or permanent fixture. Temporary greenhouses, such as those made from plastic or lightweight materials, may not require planning permission, especially if they can be easily dismantled. On the other hand, permanent structures with concrete foundations are more likely to require planning permission.
How to Apply for Planning Permission
If you determine that planning permission is required, the process is straightforward but involves several steps:
• Pre-Application Advice: Consider seeking pre-application advice from your local planning authority. This can help identify potential issues early on.
• Submit an Application: Complete and submit a planning application, which typically includes detailed plans and specifications of the proposed greenhouse.
• Wait for a Decision: The local planning authority will review your application and make a decision, usually within 8 weeks.
• Appeals: If your application is refused, you have the right to appeal the decision.
Tips for a Successful Application
• Compliance: Ensure your greenhouse design complies with local planning regulations and guidelines.
• Consultation: Engage with your neighbours, especially if the greenhouse might impact their view or property.
• Professional Help: Consider hiring an architect or planning consultant to assist with the application.
In many cases, building a greenhouse in the UK does not require planning permission, thanks to Permitted Development Rights. However, it’s crucial to understand the specific rules that apply to your property and intended use. Always check with your local planning authority if you’re unsure, as this can save you time, money, and potential legal issues down the line. With the right preparation, you can enjoy the benefits of your greenhouse without any planning headaches.
