Here’s a scenario for you: you kind of enjoy privacy, but your property is on a slope and that garden fence is not exactly covering your secret backyard deeds…
Yet, you start wondering… What if you put some trellises on top of the fence? Is there a legal height limit to that? Is a trellis even considered a fence according to your local council or is it some other kind of mystical barrier-being? Let’s dive right in.
Permitted maximum of total height for a boundary fence with trellis on top
There are three answers to be had here, and they all depend on your local authorities. Check in with them and, depending on what their garden wall policy is, you will have options. The maximum height of a garden fence with trellis on top is defined when:
- Your council treats a trellis as a fence or a garden wall. In this case, the total height of your fence and trellis should not exceed 2 metres;
- Your council treats a trellis as a “temporary structure”. The trellis on top can, therefore, exceed 2 metres. In this case, the fence itself falls under the category of “permanent structures” and thus its height limitation still remains. A ”temporary trellis” are trellises that are being used to support plants for a limited period of time (up to 28 days) during the year;
- Your council treats a trellis as a fence only if it’s physically attached to your fence. Although rare, such a regulation will require you to install a free-standing trellis with its own upright support in order to make use of its height.
Alternative fence height increasing ideas to try out
Communication is key. But what if the fence does not belong to you and your neighbour refuses to cooperate? Here are some practical fence height extension ideas for you:
- Erect your own fence right next to the neighbour’s one. So long as you adhere to the allowed garden wall height regulations and it’s standing on your property, you should be fine. The case here is that the fence belongs to your neighbour and he does not want it to reach the height limit.
- Plant freestanding mature hedges and bushes or other tall-growing plants like bamboo. These can reach 2 metres in height, acting as a living extension to your wall. If the hedge is the only boundary between you and your neighbour you will both share the responsibility of trimming it. There is also a “tall hedge” limitation of 2 metres.
- Install your own freestanding trellis and plant some climbing dense vines nearby. The vines will easily grow over 2 metres. Sightly choices would be evergreen clematis, honeysuckle, trumpet vine. Russian vine is also suitable, but it’s highly invasive, so be careful with it.
- Build a small shed or a greenhouse next to the fence. Installing outbuildings does not require planning permission so long as their height does not exceed 2.5 metres when they’re placed within 2 metres of the boundary. However, you can boost the allowed height to 4 metres if the shed or greenhouse is located more than 2 metres away from the fence.
