Important Things to Take into Consideration Before Installing a Garden Room 

Before you build a garden room, there are some things you should consider first. For example, where are you going to put the room? What type of insulation do you need? And do you need proper ventilation? These are just a few of the issues to consider before installing a garden room. If you can follow these simple guidelines, you’re on the right track. Listed below are some important things to consider before installing a garden room. 


Besides the cost of the garden room itself, there are many other factors you should consider before starting the installation process. These factors include the size of the room, the materials to be used, the lighting system, and the heating system. In addition, you should find out if you need to apply for planning permission for your garden room. Also, some garden designs require building regulations in your area. Finally, you should check the laws in your local area so that you don’t break the law by building an unauthorized room in your garden. 

The size and design of a garden room are based on its purpose. This decision should also be based on the size of the plot. Usually, timber frame garden rooms are cheaper than those made of other materials. However, extra features, delivery, and third-party labor will also influence the price. The interior finishing is also a factor that affects the price. In addition to the material, the design and decor of the garden room should match the interior of your house. 


When it comes to creating a garden room, a lot depends on your vision. The location, size, and orientation of the space are the primary considerations. Other factors to consider include your desired functions. Consider the view of the garden, a path or structure, outdoor artwork, and if you need electrical access. Here are some tips to help you create the perfect garden room. And remember to make it as relaxing as possible. Whether you want to use it for entertaining or simply relaxing, your garden room can be an extension of your home. 

The main transition area between the different garden rooms is a stone patio. Having an open space between the rooms makes the yard feel spacious. Designer Alli Guleria has repeatedly used curved lines that create an air of flow and relaxation. In addition, you should use barriers and structures to define garden rooms. This creates intimacy and privacy. Once you have determined the purpose of the garden room, you can then design its layout. You can also use pathways to link different garden rooms. 


There are many benefits to choosing insulated garden rooms over those without. The roof deck is a particularly important consideration as the warm side of the room will be protected from condensation. Warm moist air cannot condense on cold surfaces, which would be ideal. However, there are several conflicting requirements that may prevent an ideal solution. For example, permitted development rules in the UK only allow a garden room to have a height of 2.5m. Consequently, the internal ceiling height will be limited by this height. 

To ensure that the garden office is fully insulated, it is important to check the u-value of the material used for construction. Most suppliers will have worked out the u-value of their structure and published it on their specification sheet. Once you’ve gathered as much information as possible, you can then decide whether you need to install extra insulation or not. A garden room can provide useful storage space as well as an area to relax. 


Garden rooms that are poorly ventilated often experience condensation during the winter months. This is when low temperatures and humidity in the room cause water vapor in the surrounding air to condense into droplets. This moisture then sticks to cold surfaces. The vapor can be held onto these surfaces, causing a foul odor and decomposing areas. Even worse, condensation can lead to the growth of molds and bacteria and may even cause health issues. Fortunately, quality ventilation can help eliminate condensation in your garden room. 

Depending on the type of garden room, there are two basic types of ventilation systems. Passive ventilation is simple, using only wall vents. It aims to draw moist air out of the garden room while drawing fresh air in. Designed to keep the building cool during the summer, passive ventilation systems do not require electricity. Besides being the easiest way to ventilate a garden room, passive ventilation systems also reduce the need for electricity. 

Building Regulations 

If you are planning to install a garden room on your property, you should be aware of the various building regulations before you start your project. The government has set a minimum standard for all buildings and outbuildings, including garden rooms. They are intended to protect the public, conserve energy, protect the environment, and promote sustainable development. Garden rooms are normally exempt from building regulations unless they are more than 15 square meters in size, are built on land that is less than a meter from the boundary, or contains sleeping accommodation. 

If you’re planning to install a garden room, you must ensure that you are in compliance with the necessary regulations. Garden rooms are not allowed to have a balcony or raised platform, as they are considered outbuildings and may interfere with other neighbors’ views. Garden rooms cannot be built in National Parks, AONBs, or Broads, as they lack permitted development rights. And if you are constructing a garden room on a listed building, you must get permission from the local authority for any outbuilding on the property. 


Choosing the right size for your garden room is the first step in building your outdoor oasis. Whether you want Small Garden Rooms, a simple gazebo, or a fully enclosed room with windows and plenty of natural light, the size you choose will determine the materials you’ll need, as well as the overall cost of the project. Make sure you check building regulations in your local area before you start building. Then, decide on your style and start planning! 

A 3m x 3m garden room is the smallest size you can install, and it is a good size for a single desk office with ample storage space. Then, you can add a bookcase or filing cabinet. You could even install a double desk along one wall if you have enough space for both. Be sure to consider wall shelving carefully, as they will have to face each other – you don’t want people knocking their heads on it! 


Ensure that you have the correct foundations for your garden room. You can use concrete rafts, slabs, screw piles, or blocks. If you’re building on a sloped garden, you can fix your garden room with concrete blocks. Once the foundation is in place, level the surface. Then lay plasterboards. Make sure to use a leveling compound to avoid any bumps. Once the plaster has dried, you can decorate your room. 

Another factor to consider when installing a garden building is the base. You must ensure that the ground is level, otherwise, you’ll end up with a crooked structure. If the base is uneven, this will cause the building to leak and may also lead to subsidence. Then, make sure that you read the instructions on how to maintain your garden building. While many garden buildings are guaranteed for up to 10 years, Which? members have been using their summer houses for longer. 

The design and layout of your garden room are also important. The location of your garden room is important, as it affects its orientation and how it will function. The orientation can also influence the type of insulation and heating and cooling you will need. You should also think about the use of your garden room, as you may want to make it more private or use it to entertain guests. Having a separate room for storage allows you to know exactly where to store things so you can easily find them when you need them. 


There are many different factors that influence the cost of installing garden rooms. The time you can dedicate to a project and the scope of the garden room itself will determine the costs. You can buy a ready-made kit from a supplier at a lower cost, but it’s better to get professional help. Building control approval will add to the cost. And you’ll need to apply for planning permission separately. The costs vary from place to place.
