What is included in the cost of a garden room?
The ultimate cost of your perfect garden room has a lot of different elements included in it. All these various factors combine to give the actual cost of building your garden room. It is important for you to know what all these elements are in the quotation you receive from any garden room companies you enquire with.
Below is the table with all these factors explained:
| Element | Included in quote of starting price | Details |
| VAT | Most of the time | VAT refers to Value Added Tax and most companies include this in their quote. |
| Materials & delivery | Partially | Delivery charges are included in the quote within a certain radius of the business. Outside of that radius there may be extra charges. Standard materials should also be included in the quote but you may need to check for any specialist requests. |
| Installation | Most of the time | Most of the garden room installation companies include installation charges in their starting price. For some predesigned models, there can be an extra installation charge as an option. |
| Foundations | Most of the time | Most garden room manufacturing companies add the pricing of the foundations in the starting price . However, there may be some contractors that price it separately. |
| Insulation | Majority of the time | Insulation of the walls and roofs is almost always added in the pricing. There may be some that offer it as an extra option and they will let you know about that in their quotation. |
| External Cladding | Most of the time | Most of the companies include the cost of external cladding in their starting price. However, this pricing generally covers the cost of only their most basic finish. |
| Doors & Windows | Most of the time | The starting price of a garden room includes the cost of a standard door and a window in it. This door would be likely made of a uPVC material. Any customisations you need would cost extra. |
| Roofs | Most of the time | The starting price of a garden building routinely includes the price of a roof covering. This is usually for the standard options such as insulated steel or EPDM membranes. For a higher cost, there can be options to upgrade the roofing materials. |
| Lighting & Power | Majority of the time | Generally, garden room installation companies include the cost of wiring and setting up electrical outlets in their initial quote. However, should you have any lighting or electrical requirements that would be considered specialist, you should expect to pay more. |
What optional extras can add to the cost?
Customisation is key when it comes to truly making a garden room your own. Bear in mind though, the further you deviate away from what is considered a “standard build” the more you increase the price.
Interior Decoration
The basic starting cost of a garden room generally gives you a basic structure of walls, door, windows and a roof. In the event that you wish to add some elements of interior decoration to your new extra space, it would have an impact on the pricing. This interior decoration work includes customising paint colours, tiles, adding furniture etc.
Heating
The basic price of the garden room can give you insulation, however if you need a heating feature added to the room, that will include an extra cost. You can get an option to upgrade to a heating feature in the beginning as well so before you choose a plan you can make an informed decision.
Data Cables
If you want data cables installed in your garden room to allow internet access and networking then that will also add to the garden room costs. Most companies do not offer this as part of their basic pricing and charge extra for it.
Technology
A basic garden room that you get installed generally is very low tech. It generally has electrical wiring done and power outlets installed but that is about it. If you need any technological advancements added to this room, then that will also add the ultimate cost of your garden room.
Shower and toilet
The cost of a garden room with shower and toilet would obviously be more than the starting price that you are quoted. This is a special customisation that is only done based on the client’s request. The size of the bathroom and shower area would be another factor impacting the price.
Exterior lighting
If you need lights installed on the exterior of your garden office or building then this added extra will cost you more. Different types of lights and the number of lights you get installed will also change the final cost of the garden building.
Soundproofing
If you want the noise generated inside the garden room to stay inside and you want to stay away from the noise outside, you may want to soundproof it. Soundproofing is an additional customisation that would increase the cost of the room.
How the type of garden room can impact the price
There are different types of garden rooms that you can get installed. Which type of room you require and what customisations go into also play a major role in the pricing of the rooms. A truly bespoke garden room can have a lot of unique additions. However, you’ll also need to make sure you have the correct planning permission for the type of garden room you require.
Below are some of the types of rooms most garden room companies offer:
Garden Room Bar
Adding a Garden Room Bar to your home is the perfect way to entertain guests and create an atmosphere that brings people together. There are various styling options that will impact the garden room worth and cost.
Garden Room Spa
A Garden Room Spa is the perfect retreat for relaxing, refreshing and rejuvenating after a long day at work or just to escape with friends. With plenty of options available, you are sure to find something that will suit your needs within your budget.
Garden Room Gym
If you are into working out and staying healthy, then a gym in your own garden would be the perfect thing for you. You can choose what equipment you need and how to utilise the space to get the perfect garden gym. These details will play a role in the price.
Garden Room Sauna
A sauna can be a nice relaxing place where you can sweat out the stress from your mind and toxins from your body to feel refreshed. Whatever equipment and installations that are needed to convert the garden room into a sauna will add to the cost.
Can you build a garden room on a budget?
Even if you are working with a tight budget, you can very much build a garden room. As we have mentioned above, the pricing depends upon the different options you choose and the customisations that go into it. As with anything, it is best to leave building a garden room to the experts. Professional garden room suppliers can build one for you from scratch or install a prefabricated one as per requirement.
