Your cabin needs to be built on a perfectly flat surface. The foundations need to be built to the New Zealand building standard NZS3604:2011. Other options may be available so you should check with your local authorities. Whichever approach you take you must ensure they meet all relevant standards.
Lifestyle Cabins supplies foundation plans for all cabin models should you wish to use them.
We assume the site selection you have made has been in accordance with all your local regulations and Lifestyle Cabins assumes no responsibility for this. As always with any building work you should contact your local authorities to check the local regulations.
We recommend keeping the underneath of the cabin as dry and as free of vegetation as possible. We recommend placing a damp proof course (or similar like black plastic) on the ground or under the floor beam that will protect the cabin from rising damp, moisture and decay.
