Hi
He'd need a few tools to process the timber as sold by Morgans. It is sold in planks and would have to be planed down, there are large saw marks on it. This is pretty common with all hardwoods, although it may be possible to get Beech that is pre finished.
You can get pine that is ready to use from more places, like Noyeks or The Panelling Center. Or Woodworkers in Dublin will also cut the timber to the sizes you require for a small fee, I think they will only do rectangular cuts and I don't think they have much in hardwoods.
Cheers
