Woolbeding House lies in the valley of the River Rother in West Sussex, an unchanging English landscape. Time had appeared to stand still when, in 1972, Simon Sainsbury and Stewart Grimshaw leased the house and gardens from The National Trust. For over four decades, they worked with a talented team of architects, designers, and contractors to create a masterpiece of twentieth-century garden design, a Sussex Arcadia. In 'The Loveliest Valley', Grimshaw recalls catching intriguing glimpses of the house on visits to Sussex, the serendipitous nature of their purchase, and the painstaking process of breathing new life into both house and garden.
