Re: Hello all from Ontario, Canada
A few years ago I built a cabana in the garden on 5" of compacted clear gravel followed by 5" of re-inforced concrete. To date, have not seen any frost heave or cracks.
On this build I am considering of adding 2" of rigid insulation to act as thermal break on top of the drainage base followed by re-inforced concrete.
In my local municipality I can build an outdoor structure 120 sq. feet or less without a permit. Setback regulations must be followed.
