How Much Does a Garden Room Cost?

You might want the additional space for a home office, a gym or summerhouse etc. Understanding the costs involved in building an insulated garden room is important so you can budget accordingly. In this blog we will look at how much a garden room cost. 

What is a Garden Room?

A garden room is a separate standalone structure in your garden that you can use for additional space without having to build a home extension. A garden room usually includes insulated walls, roof, doors and windows and often has electrics and heating installed. It’s different to a shed as it’s designed for all year-round use. A lot of people use a garden room for:

• Home office or studio
• Gym or yoga room
• Summer house or retreat
• Workshop
• Playroom or hobby space

What Does the Cost of these Garden Rooms Actually include?

Most insulated garden room packages include the following standard components:

• Foundations such as ground screws or concrete raft
• Fully insulated floors, walls and roof
• External cladding and roofing material
• uPVC or aluminium windows and doors
• Internal finishes such as plasterboard or timber lining

However, not every quote is the same. Some companies will exclude:

• Site preparation or ground levelling

We highly recommend checking what’s included in each quote and ask your contractor about topics such as warranties, delivery distance charges and support.

Key Factors That Affect the Cost of a Garden Room

1. Size and Design Complexity

The larger the footprint and the more detailed the layout, such as large rooflights, full glass walls or a curved roof, then the more you’ll pay. This will be a higher cost for both materials and labour. A simple 9 m² design will cost a lot less than a 24 m² open plan garden room.

2. Foundations and Site Works

Site preparation will vary widely. For example:

• Ground screws – Are quick, neat and usually included in standard packages.
• Concrete raft foundations – These are more substantial and costly but are better for gyms or heavier usage.

You might need tree root removal or ground levelling before your garden room can start to be built. This will add additional costs to the overall project.

3. Quality of Materials and Insulation

High specification builds use quality timber cladding, high performance double glazing and commercial laminate or hardwood flooring. It will include better insulation in walls, roof and the floor which increases thermal performance. However, this will understandably add to the cost. Having an insulated garden room is necessary to be able to use your garden room all year round. 

4. Location and Labour

Labour rates are different across the UK. In the Southeast or London, you can expect higher installation costs. Your chosen contractor’s availability and skill levels also influence the price. Specialist garden room installers will charge more but will deliver a better finish and guarantees.

5. Extras such as Heating, Electrics and Decor

Do you want underfloor heating, bathroom plumbing, decking, bespoke cupboards or bi-folding doors?  Any of these extras can higher your costs, in some cases by several thousand pounds.

Labour and Timeline to Install Your Garden Room

Most garden rooms will take between 1 to 3 weeks to install. This depends on the size and complexity of your chosen garden room. Labour costs range from £500–£700 per day on average. 

Planning & Regulations

In the UK you usually don’t need planning permission for garden rooms under certain conditions:

• The garden room is single storey and has a height under 2.5 m (or 3 m for pitched roof) and is located at rear of property.
• The garden room is not used as independent living accommodation.
• The garden room covers less than half the garden area. 

Building regulations might apply if you install mains electricity or heating. You should ask your contractor about planning and building regulations before work is carried out. 

How to Choose a Contractor to Build Your Garden Room?
