How are our garden studios constructed?

Floor, base and walls


4×2 treated timber with 25mm foiled back insulation, sandwiched between a 9mm OSB3 and 12mm laminated oak effect flooring.

4″ concrete base with reinforcing metal.

Our garden rooms are built just like timber frame houses with the same size timber and breather membrane. Timber is 4×2 studding covered with 9mm OBS board and insulated with 50mm insulation, which is the same as is used in modern buildings.

Internal Finish

  • Walls will be plaster boarded and plastered ready for the customer to finish in a paint of their choice.

  • Laminate flooring

  • Skirting boards are then fitted to complete the finish.


External Finish
Externally, garden rooms are finished with a choice of cladding:

  • 40mm tantalized log-lap finish

  • PVC wood-grain cladding in a choice of colours

  • Natural cedar cladding with an expected 40-year lifespan without further treatment. This is a premium finish and therefore an additional charge applies.

Cedar room finish
Your cedar room will be sanded with a very fine sandpaper to give it the best finish possible then oiled with a protective covering.


Again, just like modern houses, we use 4×2 timber with a wooden beam through the peak of the ceiling, which creates a vaulted ceiling to provide an airy feeling. The ceiling is finished with a white tongue and groove effect, which is both light and easy to clean.

Externally, the roof is felted and battened and finished with Cromleigh slates or a slate of your choice. Or you can have a flat roof which is made up with a 6 x 2 timber with a 18mm OSB board on top, covered with Firestone rubber cut to size so there are no joins or leaks.


The soffits and fascias will match the doors and windows.


Half round gutters with round downpipes, which complete the finish. We are also registered fitters of Firestone rubber roofing.

How do I obtain planning permission?

We support you every step of the way.

Under regulations that came out in October 2008, outbuildings are considered to be a permitted development and as such may not require planning permission subject to certain restrictions and conditions.


Details on the relevant planning rules can be found on the Planning Portal. We recommend customers consult with their local authority to determine if planning permission is required.

In our experience the majority of garden rooms in the rear of a property do not need planning permission. Where planning permission is required, we can use a CAD architect program to assist you with your planning application, and provide you with 2D and 3D plans of your garden room drawn to your specific requirements.

Garden Room Wales is happy to support you to determine if planning permission is required, but ultimately compliance with planning requirements rests with the homeowners.
