I think they will get into property development - it is a good way to make money.Haven't thought about them for ages. Just had a look. That garish extension is totally out of keeping with the original property. I really hate it when people do this to old houses - you see it all the time on Instagram. They take all the character out of them and make them look like new builds.
And why do two men, with no children, need such a big house unless they really do think they are property developers now and are literally going to do it up and flip it?
I have childfree couples who live in big houses. It's better than living in a cramped house knowing you can afford bigger.
