Understanding Planning Permission for Garden Cabins

First of all, it is important for you to understand what planning permission is before going into the details. A planning permission is a formal approval from the local planning authority that you need to have from your local authorities before you can make changes to your property.

Even though this might sound like a complicated and long process requirement, it is very important because it’ll make sure that the structures are built in a way that is not against safety standards and seems reasonable with the area’s development plan.

Exemption from Planning Permission

The great news is that many garden cabins do not require planning permission before adding them to your property as they are exempt from planning. The most important thing is to make sure the garden cabins meet the guidelines that govern the size and location of the structure.

In Ireland, all houses are allowed to build a garden cabin in their back garden up to a size of 25 m2 without having to get planning permission before doing so. 25 m2 is a fair size that can serve many purposes, from a home office to a studio or a relaxation space.

But there’s an important factor that you shouldn’t overlook when planning for this.

You’re supposed to leave more than 25 m2 of free space in the garden after building the less than 25 m2 garden  cabin. This is just to make sure your property has an open area and doesn’t overshadow the environment.

Why the Size Matters

If you’re wondering why there is a restriction on size, it is because the restriction creates a balance between the homeowner’s wish for additional space and the whole community’s interest. If a garden cabin is unnecessarily large, it can affect the neighbors, by blocking natural light and automatically changing the overall area’s uniqueness.

When the guideline of keeping the garden cabin below 25 m2 is followed, these issues will be greatly prevented. It is a size that gives you functional space without affecting the property or causing fights with neighbors.

Garden Cabins: Beyond Just an Extra Room

An interesting attraction of garden cabins is that they serve many purposes. They can be designed as:

Home Office: A lot of people work from home now. Creating a separate, quiet space for yourself to work in is very important. Garden cabins will give you the chance to work peacefully away from the distraction of the main house.

Art or Music Studio: For someone who creates art, a garden cabins can be a safe place. Because it is detached from the main home, it means less noise, which is perfect for you to make music or create art.

Relaxation Space: Picture yourself in a quiet reading corner or a yoga space in your garden. The fresh air it brings can be your perfect escape from daily life.

It is important for you to note that even though garden rooms are very useful, they come with certain ways in which they should be used. If the garden room is to serve for accommodation purposes, that is, if someone plans to sleep in it regularly, then getting planning permission will be needed.

When to Seek Advice

It might seem that the guidelines are straightforward, but depending on the details of your property and the garden cabin’s design, there might be slight differences.

For example, factors like nearness to property boundaries, roof height or whether the garden cabin will need plumbing can influence the need for planning permission. In case you’re in doubt, it is always advisable to meet with local authorities or visit the planning department that handles this. This will not only help you understand better, but it will also make sure you avoid potential legal problems in the future.
