"ā¦There was a lot of chainsaw work involved in notching and grooving the logs so they fitted together perfectly to keep the wind and rain out. Putting together the corbelled roof ā continuously crossing the angles to gradually bring the roof towards the centre and cover the space ā was a fascinating process.

And finally we put up the turf, taken from the meadows of Cae Mabon.ā¦"
