Gilbert-Green has had a strong few years, selling £100 millionworth of property to ‘the great and the good — lords and ladies, billionaire international businessmen, global superstar celebrities and top developers’. That’s without mentioning achieving record figures on Cadogan Square, South Eaton Place, St James’s Street and the most expensive mews sale in London —on Pont Street Mews — for £11.8 million. ‘What we’ve seen since 2008 is that London is pretty bulletproof… If you bought something in super-prime London, you would have to have made a very big mistake to go wrong with that,’ he says. The ‘pro-active, professional and passionate,’ adviser’s most memorable experience? The first One Hyde Park resale for £17 million —£6,000 per square foot.
