He read modern history at Oxford University, and became a contributor to Country Life magazine. He was appointed as the magazine's Architectural Editor in 1907 and became recognised as one of the leading authorities on the history, architecture, furnishings and gardens of English houses.
He also worked as a garden designer in the Arts and Crafts style, and was a friend of Gertrude Jekyll and Harold Peto. His garden design works include the walled garden at Chequers, and several in his home county of Monmouthshire. These include Mathern Palace, Mounton House, High Glanau Manor, and Wyndcliffe Court. His gardens were characterised by divided compartments with sculpted yew hedging, topiary birds and animals, long grass bowling greens, lush planting and wild areas.
His books included The Story of the Royal Welch Fusiliers (1915), English Gardens (1925), Old English Furniture (1928), English Homes (1929), and The Garden of Today (1933).
