Garden rooms are all the rage right now, and for good reason! They’re super versatile and can be used for a bunch of different purposes.

You can use a garden room as a home office, gym, creative studio, extra guest accommodation, or a leisure room. It provides the ideal solution for extra space.

But the big question is, how do you figure out what size garden room is right for your property?

Don’t worry, we’ve got you covered! In this post, we’ll walk you through everything you need to consider when selecting a garden room size, and show you all the different options available to help you find the perfect fit.

Considerations When Choosing the Right Size Garden Room:

Before you begin thinking about the size of your garden room, there are several key considerations to keep in mind.

Intended Purpose

Firstly, think about the purpose of your garden room. What will you be using it for? If you plan to use it as a home office or gym, you may only need a small to medium-sized garden room. However, if you’re planning on accommodating guests or using it as a leisure room, you may need a larger space.

Available Space in your Property

Next, you’ll need to consider the available space in your garden. For this you’ll need to measure the area where you plan to install the garden room, as you’ll need to ensure that it fits comfortably within the available space.

It’s also important to consider the positioning of the garden room, as this can impact its size and shape.

Planning Permissions and Regulations

In addition, you’ll need to check any planning permissions and regulations in your area before installing a garden room. These rules can vary depending on where you live and the size and placement of your garden room, but typically In the UK, there are specific rules around garden rooms that you need to be aware of.

If your garden room is under 2.5 metres in height and doesn’t take up more than 50% of your garden, you likely won’t need planning permission. However, if your garden room is larger than this, you’ll need to apply for planning permission before you can start building.

There are also some other regulations to keep in mind. For example, if your garden room is going to be located within two metres of your property boundary, it cannot be taller than 2.5 metres. Additionally, if you’re planning on using your garden room for sleeping accommodation, it will need to comply with building regulations for insulation, fire safety, and ventilation.

So, even before you start planning the size and layout of your garden room, make sure you do your research and check any planning permissions and regulations in your area. This will help ensure that your garden room project goes smoothly and that you don’t run into any unexpected roadblocks along the way.

Finally, budget is an important consideration. The cost of a garden room will vary depending on its size, materials, and features but will typically range from £10,000 to £25,000 for a larger size.

But that’s not, you’ll also need to factor in ongoing maintenance costs, as well as the potential return on investment when it comes time to sell your property.

Size Options for Garden Rooms

Once you’ve considered these key factors, it’s time to explore the different size options for garden rooms. Here are three typical size categories to consider:

Small Garden Rooms:

Small garden rooms typically measure between 2.5m x 2.5m and 3m x 3.75m. These garden rooms are ideal for storage or single-purpose use, such as a home office or a yoga studio. They’re also a great choice if you have limited space in your garden, as they can fit comfortably into a corner or against a fence.

One of the main benefits of small garden rooms is that they’re relatively inexpensive to install and maintain. However, the downside is that they may not be suitable for larger groups or multi-purpose use.

Medium-Sized Garden Rooms:

Medium-sized garden rooms typically measure between 3m x 4m and 3m x 6m. These garden rooms are versatile and practical for multi-purpose use, such as a gym, guest accommodation, or a leisure room. They offer more space than small garden rooms, without taking up too much of your garden.

The benefits of medium-sized garden rooms are that they provide more space and flexibility, without being too expensive to install or maintain. However, they may still be too small for some purposes or larger families.

Large Garden Rooms:

Large garden rooms typically any size above 4m x 5m and 5m x 6m. These garden rooms are spacious and luxurious, offering plenty of room for a range of uses, including a home cinema, a music studio, or even a small business office. They’re a great choice if you have a larger garden and want a multi-purpose space that can accommodate large groups.

The benefits of large garden rooms are that they offer plenty of space and flexibility for a range of uses. However, they’re also the most expensive to install and maintain, and may require planning permissions.

Choosing the Right Size Garden Room for Your Needs

Once you have considered the above factors and the size options available, it’s time to choose the right size garden room for your needs.

The first step is to match the garden room size with the intended use. Consider the space required for each purpose, such as a desk and chair for a home office or equipment for a gym. Make sure that the garden room provides enough space for your intended use, as well as any potential future uses.

Next, think about your lifestyle and personal preferences. Do you enjoy entertaining guests or having a private space to relax? Do you have a large family or often host events? Consider these factors when choosing the right size garden room.

Finally, it’s important to ensure that the garden room blends with the overall property design. Choose a style and color that complements the existing architecture, and consider adding landscaping or outdoor furniture to enhance the space.
