Once a cherished writers’ retreat where several books were written, this magical dividable 18-acre San Juan Island property is a haven of creativity and tranquility. The 3,648 sf home is designed with versatility in mind, offering essentially two complete living spaces—each with its own kitchen, bedroom, bathroom, and living room—ideal for multi-generational living or guest accommodations. A separate 320 sf guest cottage with bath adds even more flexibility. Thoughtful updates include laminate flooring, refreshed bathrooms, newer heating system, expansive decking, and a saltwater hot tub. The grounds are equally magical, with fruit trees, ponds, mature landscaping, a 2 stall horse paddock, an artist’s shop, and a mystical forest to explore.
