Kevin was a bit snooty but, to be honest, I largely agree with his reasons. There were so many original features of those buildings that could, and arguably should, have been preserved. But they weren't.
From the outside, at least, the guildhall lost nearly all its character and the big barn ended up looking like an anonymous small office unit.
It didn't help that the bloke was an annoying pillock. I couldn't believe the way he just ignored everyone else's opinions, even even those of his wife.
Pah. Not one of my favourite episodes.
