I think it's lovely, I like clutter and having beautiful things on display. It's very 'London media type' style though, I've seen loads of houses of famous people like this over the years.
Really shocked by the fake grass though (which it very obviously is - and I bet it's the pricey kind that people claim looks real) - I would have thought he'd be far too ecologically aware for that.
Also, I really, really do not think that anyone in Ben Fogle's family is doing the dusting. If you live in a house like that you have a cleaner, probably multiple times a week.
