Ann Brooke has been designing and installing gardens, large and small, since 1987 — penthouses in New York City, Brooklyn brownstones, second homes and country estates in Connecticut, Massachusetts, Shelter Island and Colorado, schools in Brooklyn, and playgrounds in Colorado and New York. She recently relocated to Washington and is enjoying the opportunity to work in a new and more temperate environment. Ann grew up outside Sydney in a part of Australia full of lush, serene, sophisticated gardens whose English style had been adapted to a very different climate and landscape. Her landscape practice (Ann Brooke Landscape Design LLC) draws on that history of flexible and creative adaptation. Her volunteer work for Tregaron has included Shipman-inspired woodland garden design, tree planting plans, and supervising landscape installations.
