About Your Order

High-quality timbers are used throughout the construction of the garden building. Mercia garden rooms are installed by a team of professional installers.

Delivery And Installation Information?

Since this building includes free professional installation, there’s hardly any effort required on your part!

You will need to ensure there is a 24” clearance all the way around the building and have the area cleared and ready on the day.  This will allow for the building to be assembled and for you to be able to treat the building.

Once your order is placed, the manufacturer’s installation team will be in touch with a short pre-installation questionnaire. This helps us confirm that the site for your new Insulated Garden Room is ready, making sure everything runs smoothly on installation day. 

After the foundation is set and access to your garden is clear, our installers will take care of the rest!

Note: The installation team will not dismantle or remove any old buildings.

Aftercare & Guarantee:

The garden room is supplied untreated. You must apply a preservative and waterproofing topcoat immediately after installation. Using the treatment after installation, followed by consistent annual treatment of the garden room, will maintain the high-quality finish and is a requirement of the 10-year anti-rot guarantee. A 1-year manufacturer's warranty is included as standard.

To treat the garden room, elbec recommends Protek wood treatment. Browse our Protek Royal Exterior Wood Finish Paint range to find the best paint colour to add your own personalised finish.  We’ve also included in the options section some popular colours and a Wood Preserver+ to be used underneath the colour of your choice.

Planning Permission - Do You Need It?

The garden building designs have been created to adhere to planning permission guidelines. However, we cannot guarantee that you will not need planning permission for a garden building.  We advise checking with your local authorities before constructing your garden room. 

Garden Room Base Requirements?

A flat, level base is required for the installation of your Insulated Garden Room. You can purchase the Mercia Elite Timber Base with Ground Screws.  For more information on how to build a garden room base, you can contact us.

Prior to the Garden Room installation, be sure to check the base is level in all directions. If the base is not level, it will cause the building to twist and warp with the natural movement of the timber. It’s essential to adjust your base accordingly to achieve this before the installation process begins.
