Frequently Asked Questions


Before installing your Telluria building, you must have a flat and level foundation. Failure to create a flat/level foundation will mean spacers will be required, creating an opening under the frame where water can penetrate./p>

If you intend to use a concrete surface, this must be as smooth as possible to prevent water from passing underneath. Porous concrete, joints, etc., will not result in an absolute seal.

We recommend making the concrete slab 10 cm wider than the building itself. It is best to slope this extra 10 cm away from the construction so the water drains off naturally and does not pool against the building.
You can insulate your Telluria building; this personal preference will depend on how you intend to utilise your Telluria Garden Room. The roof comes insulated as standard, but the outer walls are not. You can place flexible 8 cm thick rock wool between the profiles and neatly finish the inside with a Telluria inner wall.
As with the insulation, your Telluria building can easily be adapted to feature electrical provisions if required. Holes are provided at various places in the panels to feed electricity provisions. To connect your Telluria to an electrical supply, you must put the electricity provisions in place before starting the construction.

The water drainage pipe is always located at the rear, right-hand side of your Telluria installation. If you opt for an extension to the left, the water drainage pipe is located at the rear on the right. If you opt for an extension to the right, the water drainage pipe is in the middle of the construction.

The following applies to the larger models below (always for a front view): Garage 3654 + 5436 Plus + Luminato 5436: The water drain pipe is located on the left-hand side at the rear.

The model type determines whether a single or double door is provided. You cannot choose this yourself. The door is always located at the front of the Telluria Elegance or Luminato installation. It is not possible to place the door on the side.
We provide a 20-year guarantee against rust on our Elegance, Luminato, garage ranges and fencing. The warranty is voided when grinding in the materials.

We offer a pay by finance option on any purchase over the value of £560.

Our simple finance options allow you to spread the cost of your purchase over 24, 36 or 48 months.Read more about our Pay by Finance option here.
