How much do garden rooms cost?
Most garden room suppliers will offer a rough pricing guide for common sizes of building, but there are many things to consider. Your particular garden may require a bespoke garden room due to its size or access.
Here are some of the different factors that will determine the overall cost of a garden room:
- The size of the garden room you want to create
- Whether you choose a modular or bespoke design
- The materials you use to build your garden room
- The design features you choose, such as doors and windows
- The interior of your garden room, for example, plastering and cladding
- Whether you need electrics or plumbing
- Whether you want a pathway created from your home to your garden room
Garden room options
If you’re choosing to create a small garden room for a space to work or to enjoy your hobbies, you may find a modular garden room is perfectly suited.
However, if you’re creating something unique, such as a garden man cave or children’s garden room, you might want to look into bespoke options that allow you to really tailor the building to your needs.
Below are some average cost guides for popular garden rooms.
Cost for a garden man cave
A garden room is a perfect solution for you if you’re looking to create a man cave for yourself. If you have the luxury of space in your garden to create your special little space for some you time, then go for it.
The cost of your garden man cave will be affected by the type of building, size and any other complexities of creating it.
A low shed with insulation and power will cost anything from £1,500 to £2,500+. Whilst a large, high-spec log cabin or custom brick-built cabin will cost anywhere from £15,000 to £30,000+.

| Large higher-spec log cabin / Custom brick-built cabin | Per project | £15,000 | £30,000 | £22,500 |
Cost for a children’s garden den
For your children a garden den would be amazing – weekends of fun definitely would be had.
Again, the cost to create a children’s garden room will be affected by the size, style and type of garden room.
A children’s garden playhouse will cost anything from £430 to £1,300+. A treehouse project usually costs around £2,500. Whilst a more advanced raised platform project if an elevated softwood deck with railing/stairs will cost anything from £2,200.
The added labour cost will usually be around £360 per day.

Cost for a small garden room
Off the shelf vs. bespoke garden rooms
When choosing the type of garden room you want, you have the option of an off the shelf modular solution, or something bespoke that is created specifically for your outdoor area.
Garden rooms are naturally quicker to build than an extension for example, as they’re detached from your home. The type of garden room that will suit you best will depend on what you want to use it for.

Garden room cost calculator
To calculate the cost of creating a garden room, you’ll first need to start with the size and style of the garden room you want. From there you need to add the cost of labour for building or installing the garden room. You’ll also need to budget for the cost of fixtures, fittings and furniture to finish off your perfect garden room – these are often costs that many homeowners forget to include when planning their garden room project.
Garden room quote
We recommend obtaining at least three quotes from our trusted tradespeople. Our request a quote feature is perfect for getting quotes – you post details about the job you want doing and we’ll send it out to local tradespeople in your area. Try it out!
Garden room hourly rates
As with many one-off home improvement projects, the cost of a garden room is usually quoted per project rather than an hourly rate for the job. That said, the installation cost for labour will usually be charged at a day rate – with a garden room usually taking 2 to 3 days to complete. The average labour cost for a garden room is around £690 per project, based on two people carrying out the work.
