Now she gives an exclusive tour of the lush gardens of Santa Barbara in her first book: Private Gardens of Santa Barbara: The Art of Outdoor Living (Gibbs Smith, 2020). Working across styles, designing gardens for historically significant estate properties, relaxed bungalows, or coastal family retreats, Margie takes her cues from her clients, their lifestyle, the architecture of the property, and the land itself. Grace Design Associates sculpts the terrain to mimic nature and layers on essential elements—organic materials, stone and plantings—to create a dynamic, living ecosystem that supports the local biome and utilizes water in the most efficient and considered way. Margie and her team have also developed expertise in the design and construction of environmentally sensitive landscapes, with particular attention paid to soil and water conservation, biodiversity, and fire-smart landscaping. Margie earned her degree in life and earth sciences from UCSC, supplemented by coursework at UCLA in Landscape Architecture, and has since designed, from concept to completion, over 350 projects. Margie’s work has been featured in top publications throughout the world including Garden Design, Traditional Home, Better Homes and Gardens, Veranda, Luxe, Sunset, Los Angeles Times and The Wall Street Journal.
