Dog grooming. Personal training studios. A place for you and your friends to hide from the kids and drink some prosecco. Whether you need space to turn your passion into profit, or you just need somewhere to unwind and chill out with friends, a Garden Room will do the trick.
A Garden Room is the (even) cooler big sister of the already amazing Gillies and Mackay sheds and summerhouses. It’s a practical and usable space, complete with lights, power, heating and even plumbing if you want it. An extra space to work, play or stay.
But how much will this little slice of heaven in the form of a Garden Room set you back?
Let’s get right into it, shall we, and talk about how much a Garden Room from Gillies and Mackay is going to cost you.
How much does it cost to install a Garden Room?
Like most things, it’s hard to give you an exact cost for your Garden Room.
- What size Garden Room do you want?
- What features and specifications do you want to be included?
- Do you want mains water?
All these things and more will alter the price of a Gillies and Mackay Garden Room. So an exact cost is out of the picture until you come and speak to us.
But that doesn’t mean we can’t give you an idea of the cost to help you figure out how much you are likely to pay for different sizes and specifications.
Our full range of Blackstone Garden Rooms cost somewhere between £13,000 and £40,000 on average.
How much does it cost to install a medium-sized Garden Room (up to 25m2)?
Looking for something a little more substantial than a small Garden Room? Maybe somewhere for a dog grooming space, a personal training studio, or a place to put the ‘never leaving home’ children – then you’ll want to go for something that is ‘maybe a bit bigger’ than the ‘wee one’.
We’re talking Garden Rooms that are up to 25m2, big enough to fit in a couple of people plus some cosy furnishings, to transform the room into whatever you need it to be.
Like my Jackie’s Art studio – one of the first Garden Rooms we built way back in the day and still looking as beautiful and creative as ever today.
This beautiful studio consists of 1 set of french doors, 4 standard sidelights, 1 narrow sidelight, 1 casement, and front veranda/canopy.
This is how much something like my studio would cost:
External building size: 3.6m x 4.8m (4.5m x 4.8m inc. veranda/canopy)
Full body = £15,723.00
Steel Box Profile Roofing = £1,800.00
Fitting and finishing = £2,400.00
French doors = £2,000.00
Sidelights (x4) = £3,200.00
Opening casement window = £650.00
Veranda canopy = £1,800.00
Laminate flooring = £1,745.00
Guttering = £340.00
Total = £29,658.00
But, you might want something a little different, and that’s okay. Every Garden Room will be a little different, which will inevitably change the overall cost.
Not a problem though as this post will give you an idea of roughly how much a building of this approximate size will cost.
There are also some other factors to consider below, that will affect the overall cost of your Garden Room. They include:
- Planning permission/building control
- Groundworks preparation
- Electrical installation
How much will planning permission or building control for a Garden Room cost?
If you are going for something ‘maybe a bit bigger’ then you’ll usually be within permitted development, unless you want to tap into the mains water supply.
This is good news, as it means that you won’t need a building warrant or engineer certificates and you can save money in architects, engineers and application fees.
Fantastic! Who doesn’t love to save some money?
However, you might still need planning permission though.
You won’t need planning permission providing you comply with the following:
- the Garden Room is located at the back of the house,
- it is not used as a separate home to live in,
- the Garden Room and any other development, does not take up half or more of the ‘curtilage’ (this means half or more of the grounds behind your home),
- it’s not higher than 4 metres at the highest point,
- any part of the Garden Room that’s a metre or less from the boundary is no higher than 2.5 metres,
- the eaves (the part where the wall meets the roof) are no higher than 3 metres,
- if the land is in a conservation area or in the grounds of a listed building and the Garden Room has a footprint of less than 4 square metres.

If you comply with ALL of the above then you don’t need to apply for planning permission. And assuming you don’t need a building warrant you are good to go for the installation of your Garden Room.
If you don’t comply with all of the above, then no need to worry. Getting planning permission can seem like a daunting process, but it’s actually pretty simple and straightforward. And best of all it isn’t too expensive.
You’ll need scale drawings of the Garden Room and the site plan to show where you are putting the building in relation to your house and the rest of your garden.
How much will this cost?
If you want us to take care of all the planning and submit the applications as well as elevation drawings then we can do all of this for £650.
Otherwise, you can get standard elevation drawings for around £240 and submit your own planning application for £202.
You’ll need to factor this in on top of your garden building costs if you think that it will be necessary.
How much does ground preparation for a Garden Room cost?
Our rooms are fairly hefty, to say the least. Typically Garden Rooms weigh over 2 tonnes. And the weight has a massive influence over what type of base you should construct. You need to make sure that the correct foundations are installed to ensure the longevity of the building.
We don’t deal with the Garden Room groundworks. We leave that to the professionals – who are skilled in groundworks. We can recommend some pretty great companies that we are used to working with, to help you prepare the ground for your brand new Garden Room.
The groundworks costs aren’t included in the above Garden Room costs, so you will need to factor this cost in as an additional item.
So how much do groundworks for a Garden Room cost on average?
The most important thing to consider with the groundworks is that they are completely dependent on the existing ground level and access conditions.
Both factors affect the level of labour that will be required to prepare the site and will, therefore, affect the price. Every site is different, so it’s difficult to give a ‘ballpark’ figure until the site has been assessed. This is worth keeping in mind, as this price may not be particularly accurate if you have extenuating site circumstances.
There are two options for preparing the ground for a Garden Room. A concrete plinth or ground screws.
A concrete plinth is the traditional and most common base for a Garden Room. This will typically cost you around £2,000 – £4,000 for a small to medium-sized Garden Room depending on the access and ground conditions.
Ground screws are much less damaging to the environment than a concrete base and are usually around £1,000 – £3,000 for a small to medium-sized Garden Room, again, dependent on access and level conditions.
How much will an electrical supply for my Garden Room cost me?
Lights. Heating. Power.
The three things that you need to transform your Garden Room into a cosy space to live, work and relax in.
We can easily hook you up with an electrician without any added complexity. We recommend Robert Clark who are used to working with G&M buildings.
The cost of the electrical installation for your Garden Room will depend on the distance of the Garden Room from the main electrical box in your home. And it will depend on the electrical specifications you are looking for.
A standard cost for electrics within a small to medium-sized Garden Room will be around £1,500 – £2,000.00
When you are looking for a Garden Room for a couple of people to work in. Or to give that kid that just won’t leave home a little alone space, then you’ll probably need to go for something ‘maybe a bit bigger’ than our wee Garden Rooms.
They are more expensive than our wee ones. But with that extra bit of much-needed space and added flexibility, don’t you think it’s worth it.
