Installation & Construction
Do you need planning permission?
No, all our cabins fall within permitted development. This is due to them being under 4 metres in height and below 30m2 internal space. If a cabin goes over 2.5 metres in height then you will be required to leave adequate space between you and any neighbouring boundaries, we advocate a site survey and would be able to suitably advise you.
Is construction included in the price?
Yes, all our packages include full construction. This is undertaken by our specialist installation teams who are all fully employed by Johnsons. We DO NOT use any sub-contractors.
Do you use subcontractors for your installations?
No we do not. To ensure the highest quality of your installation and longevity of your cabin, all our buildings are installed by our very own Johnsons trained staff.
How long does it take to build the garden room?
The majority of our garden rooms can be installed within 2 days dependent upon your garden room selection.
Do you supply basework? And if so what basework do you use?
We do, our chosen method is called a ‘Structural Timber Base’. This entails a post and beam method, where we concrete posts 18-24 inches into the ground and lay beams across. This is a lot more cost effective (and better for the environment) than concrete. This method also allows for good ventilation under the cabin to eradicate the chance of your timber rotting and elevates you slightly to ensure no water damage is done.
How far away from the boundary do they need to be?
You will need to treat your timber throughout its life, so we would always recommend leaving an adequate gap big enough to fit a person through. Then dependent on the height of your building will depend on the space you would need to leave between your cabin and any neighbouring boundaries.
Do you check the site prior to installation?
We offer a free site visit to all potential customers throughout Kent and Essex giving you the opportunity pre-sale to discuss all your cabin requirements, option and any other questions you might have.
One of our experienced team members will measure your garden, assess ground level, check access and confirm the best position for your brand new cabin.
We take pride in making sure we supply you the perfect cabin that meets your every need, and this process is an essential part of this.
Garden Room Specific

Our cabins are of the very best quality and are built to last. To ensure your cabin has a long life span it is imperative to treat your timber every 5 years with paint preservative.

What timber do you use?
Here at Johnsons we use Siberian spruce timber. All of our timber is sourced from sustainable forests in countries with colder climates, so the wood is closer grained and heavier, avoiding the more open grained wood that has a greater tendency to twist or warp.
