Make sure you make the best possible use out of your Log Cabin, whatever the season. Dunster House’s combination of insulation in the wall logs, floor and roofing allow you to keep the temperature in the cabin just right and use it whenever you wish.

You will need to prepare a solid base that is square and level to allow you to build this insulated log cabin successfully on your property. You can use concrete or our RapidGrid Foundation system. We recommend a base of 5.0m x 3.2m for the Severn Warmalog®. The only extras needed are a superior quality light coloured 'Barn' paint to seal the outside of the insulated log cabin, as well as a clear silicone sealer for the joints after decorating. These are available from your local decorator supplies.

Our thermally-insulated Warmalog® cabins are built of special logs - consisting of triple Tongue and Groove logs with a 62mm timber and polyurethane ‘sandwich’, that has better thermal insulation characteristics than competing brands, but at a very reasonable price. Just another new and exciting product, thanks to Dunster House!

As well as the walls of the Warmalog® Cabin, the 50mm floor and 60mm roof provide considerable insulation. The windows are Double-Glazed, with two panes of 4mm toughened glass and a 16mm air gap in a 24mm sealed window unit. These and more thermal design factors give Warmalog® cabins a U value of 0.59. This excellent heat retention makes the Warmalog® the kind of building that will keep you cool in those warmer months while staying warm in the coolest part of the year.

The Warmalog® quality timber building is well-suited to a number of uses, such as an office, work-out room or even your own private bar. So, if you need the extra room for working out or to work or  any other reason, it’s reassuring to know that the changing seasons won’t affect your lifestyle. You can keep on doing what you need to do regardless of the weather! Strong and secure, the Warmalog® has an Espagnolette locking system on its wide-opening French Doors. The roof is held up and strengthened by large Purlin beams, and below your feet, pressure treated floor bearers keep the damp away from the body of the cabin.

The Warmalog® is easy for home owners to assemble. Log Cabins will never be the same again!

Assisted Delivery

If you cannot provide an able-bodied person to offload the vehicle with the help of our driver, we can provide additional manpower with our Assisted Delivery Service. The driver will arrive with some help to unload the lorry, meaning that you can put your feet up.


Please note that items can be carried up to 50 metres from the kerbside to your place of choice as long as the route doesn’t go through a house (or any decorated building) and that there is sufficient space (at least 750mm wide) for the drivers to handle heavy pieces safely. Our drivers will be responsible for assessing the risk of carrying out a Two-Person Delivery upon arrival at the property. If they feel that there is no clear access as stated above, they will have to leave the items at the kerbside.


We offer this service on most items that are delivered, we do not offer this on our couriered products. Prices for this service can be found on individual products.
