24, The Firs, Hampstead, North London Simon continues his look at some of the best of modern British architecture, visiting The Firs in Hampstead, designed in the late 50s by one of the lesser known but highly-regarded British architect, Patrick Gwynne. Today it is the family home of William and Sharon Sargent, whom Simon visits for a weekend to learn more about Gwynne and his lavish design. The climax of the weekend is a relaxed and entertaining garden party. (architect: Patrick Gwynne)
