Design Your Own Garden Room
Create your own garden room in minutes with our free online design tool. Choose your size, pick different cladding on every side, add your doors, windows, flooring and electrics, then send it over for an accurate price.
Our free garden room design tool lets you create your own garden room exactly the way you want it. It is simple, quick and there is no cost and no obligation. You answer a few easy questions about size, cladding, doors, windows, flooring and electrics, and we use your design to send you an accurate, tailored price.
The tool has recently been made much simpler to use. The biggest change is that you can now choose a different cladding on each side of your garden room. That means you can put premium cedar on the front where it is seen, and a lower cost, maintenance free option on the sides facing a fence. It is a small detail that can make a real difference to both the look and the final price.
How do I design my own garden room? Open the free online tool, set a custom width and length, choose whether you want a roof overhang with spotlights, then pick the cladding, doors and windows for each side, your flooring and your electrical package. Send the design to us and we will come back to you with an accurate price, usually within 24 hours on a weekday.

Why design your own garden room online
Building your own garden room design before you speak to anyone puts you in control. You can try different sizes, mix and match cladding, move doors and windows around, and get a feel for the space that suits your garden and your budget. There is no pressure and no salesperson, just you and the design.
When you are happy, you send it to us and we do the rest. Because we can see exactly what you have chosen, the price we give you is based on your actual design rather than a rough guess. It is the fastest way to get a realistic, tailored figure for a fully installed garden room.
How to create your own garden room in 7 simple steps
The whole thing is just a few simple questions, and it takes most people under ten minutes. Here is what you will do.
Choose your size
Under Dimensions, select Custom and set your width and length. Get as close as you can to the size you want. We build any size, but to keep the tool simple the sizes go up in half panel steps of 600mm. Other sizes are available, it is simply too much to list every single one, so pick the nearest and we will confirm the exact size with you.
Add a roof overhang with spotlights
Decide whether you would like a roof overhang with spotlights, and choose which elevations you want it on. The overhang gives a lovely covered area and the spotlights add soft, ambient light in the evening.
Choose the cladding for each side
Pick the cladding for each side of your garden room. You can have the same finish all the way round, or mix them, for example cedar on the front and a cost effective, maintenance free cladding on the sides facing a fence.
Choose the doors and windows for each side
Add the doors and windows you want on each side. Position them wherever suits your layout and the way you will use the space, and swap or move them as many times as you like.
Pick your flooring colour
Choose the colour of your flooring to finish the inside of the room the way you want it.
Choose your electrical package
Select the electrical package for your garden room, covering the lighting, sockets and heating you will need to use the space comfortably all year round.

Design your own garden room: FAQs
Is the garden room design tool free to use?
Yes. The tool is completely free and there is no obligation. You only share your details when you are ready to send us your design, and we use them only to reply to your enquiry.
Can I have different cladding on each side of my garden room?
Yes, and this is one of the best features of the new tool. You can choose a different cladding for each side, for example premium cedar on the front and a lower cost, maintenance free cladding on the sides facing a fence. It can change both the look and the final price.
What sizes can I choose?
You can set any custom width and length. To keep the tool simple, the sizes go up in half panel steps of 600mm, so pick the nearest size to what you want. We build any size, so we will confirm the exact dimensions with you when we discuss your design.
Do I get a price straight away?
Not instantly. Once you send your design, someone will be in touch to talk it through and give you an accurate, tailored price rather than a rough estimate. We normally reply within 24 hours on a weekday, often sooner, or within 48 hours at a weekend.
Do I have to design the whole thing myself?
No. Most people enjoy creating their own design, but if you would rather talk it through, just call us on 020 3818 5911 or email sales@myretreatgardenrooms.co.uk and we will design it with you.
What happens after I send my design?
We review your design and get in touch to confirm the details and give you an accurate price. If everything looks good, the next step is a free site visit so we can finalise the design and specification in person.
