A few sheddies have log cabins, and you do need the space to have them, but if you are on the look out for a new one, then Garden Buildings Direct has expanded their range with the BillyOh Pathfinder ‘Huntsman‘ Log Cabin and the BillyOh Pathfinder ‘Woodman‘ Log Cabin.
I do like the Huntsman, could be some sort of Shed based office.
Of course if you get one please Share your shed!
