Through various contacts and our wonderful tree surgeon Lee, we have managed to source all the wood we needed.
The uprights will be oak with ring beam sections of oak, beech and (very thick) hazel. The rafters were intended to be ash due to its strength and straight nature, however a very generous benefactor has offered us some wonderful sycamore which is more than up to the job.
We have surveyed the site for the build and agreed that there will need to be a 5m square platform levelled with a small amount of cut & fill. The turf will be stacked for either the roof or a turf section of wall.
Lee helped us deliver much of the necessary wood to the site so we were ready to go once the school is ready.
Here are some images of the location and the timbers ready for use:
