The floor and roofs are comprised of heavy duty 19mm thick tongue & groove boards to ensure the log cabin is robust and durable.

Doors, Locking System & Windows

The Marple Insulated Pent Cabin comes complete with joinery-made double doors and ‘Casement’ Opening Windows. All glass is both toughened and double glazed – perfect for extra security and insulation. Not only is there the toughened double glazing, but there is a secure mortice lock system on the doors, therefore, whether you plan to use the log cabin for storage, or for a garden office, this extra secure space will provide that additional peace of mind.


This insulated cabin is supplied with untreated timber as standard, however you can upgrade to pressure-treated Tanalised™ timber which protects your cabin from rot & decay.


The 66mm, modular panels allow you to build your cabin with confidence, knowing everything fits tightly and is where it should be. Fixings and instructions are included to allow you to build the cabin yourself, however we may be able to offer a professional assembly in your area. Please check before ordering.

How are these insulated cabins delivered?

  • Your cabin will arrive with modular, pre-fitted EcoQuilt™ insulated panels. This makes access into your garden, and assembly easy, and the 27x44mm internal framing makes for a really strong building.

What about assembly?

  • These buildings are simple and easy to build, and we also provide easy-to-follow digital instructions.

What are the different treatment types?

  • These buildings are supplied untreated, however we can also supply them with a Tanalised® pressure treatment is where chemical preservatives are forced deep into the wood’s fibres to resist rot, decay and termites. Pressure treatment gives the wood on your building an extra level of protection and is an effective way of making your building long-lasting. We recommend that a high quality paint/preservative is applied straight away to the untreated cabins, and if you don’t intend to change the colour of your pressure-treated building, then a water-repellent will be ideal.

Do they come with any warranty?

  • Yes, if going with the Tanalised® (pressure-treated) version, then the wood on your log cabin is protected against rot, decay and insect infestation for up to15-years (timber splits or warping, which may occur naturally over time are not covered).

Will my cabin need a base?

  • Yes, all garden buildings should be assembled on a firm and level base, and we always recommend a concrete base where possible. A good, sold, level base will ensure your building goes together easily, and lasts for many, many years. In order to protect your building from moisture, you should leave a 2ft (60cm) gap around the exterior of your building.
