‘It’s been an interesting year,’ says Grillo, who counts ‘families of famous billionaires, non-doms, international architects of note, hedge fund gurus, financiers and multigenerational landed families’ among his clients. A chartered surveyor with twenty years’ rural experience, Grillo has focused on prime and super-prime country houses and estates since 1999. ‘I don’t think people understand how delicate [the market] is, particularly the prime and super-prime sector,’ he says. ‘There aren’t that many really good houses in the country, and there aren’t that many buyers with the true ability to purchase — therefore sentiment is key to seeing and understanding the value. That sentiment can ebb and flow.’ Grillo moved from humberts to Prime Purchase in June 2015.
