The new roundhouse at the Irish National Heritage Park in County Wexford. This looks to be a good strong house, and an interesting one too, for the double-skinned wattle wall will be filled with crushed sea shells. However, it is odd that the rafters do not rest directly onto the large wall posts, but rest on rather thin-looking wall-plate . A small bird's mouth joint into the base of the rafters to match a similar slope cut onto the top of the wall post, would make for a strong union and provide excellent weight transfer. The taller posts situated inside the house may be somewhat unnecessary, but here too lap joints would've helped to take the load of that thick thatch.
