Has anyone got any experience of living in a cob house? We've had an offer accepted on a lovely little cottage made of cob and, while we're really excited, I've woken up this morning feeling a bit panicked? Is there anything we should know about cob houses? Can we hammer nails into the walls to hang pictures or the tv (I'm imagining the wall just crumbling away which I'm sure is just silly, right?). I read cob houses were good at keeping a cool temp in hot countries but what does this mean for English winters? Will it be freezing inside? It only has electric heaters at the moment but would installing central heating be harder with the walls being cob?
