It is of paramount importance that your Man Cave Garden Room rests on a sturdy foundation. If the foundation is not properly prepared then it may affect the durability and lifespan of your cabin.

Problems that can occur include:

  • Cracks in the structure of your Garden Room
  • The shape of the building may be altered, resulting in alignment issues with doors and windows, along with spaces forming between the timber
  • Insulation will as a result be affected
  • In extreme cases, improper foundation can result in a structure completely collapsing

It is recommended that you construct your foundation using concrete and apply some form of waterproof sealing for insulation. It should be tightly compacted and consist of the same material – do not build your cabin on uneven or soft ground or, for example, halfway on block paving and halfway on grass.

As this is the case, we recommend consulting a professional contractor if you are unsure as to the quality of your foundation or how to prepare it on your own.

The drawing provided is provided as a guideline for the proper foundation required for your Man Cave Garden Room.

Important – if your foundation is improperly constructed then your warranty will become void, so it is of paramount importance that you adhere to our instructions. 


The wood of your Man Cave Garden Room will naturally deteriorate without the proper treatment. We recommend treating the wood with some form of preservative as is required for all wood products. This is especially important when it comes to the doors and windows of your garden room in order to prevent the build up of moisture which can cause problems with damp. If the wood is not treated then this can also have an adverse effect on its appearance, with a changing of colour.

It is also recommended that you maintain your cabin while not in use, airing it out on a regular basis, which will also help prevent moisture build up and damp issues.

In addition, we also recommend for the lifespan of your cabin that you paint it with paint designed to protect against the elements. This will require a paint designed for unprocessed softwoods

If you have any questions about maintenance of our garden room products, please contact us.

Usage and Safety

    • Always keep fire safety equipment nearby, including a fire extinguisher, and take care if using camping equipment that puts the inhabitants at risk of carbon monoxide poisoning. It is also recommended you install a smoke alarm.
