Base Recommendations:

We recommend a RapidPad™ foundation System for all Log Cabins. This base system is designed for our cabins and can support them on most types of ground. It also includes an insulated floor. Click here for full details

If you wish to use concrete, it is recommended that you take your log cabins size and add 100mm all the way round to calculate the size of the base required.
