28 imaginative tree houses, ranging from kids' fantasy play areas to family retreats and adult hideaways in the UK-based Blue Forest. Enter the world of fairy-tale towers, whimsical stairways, crow's nests, zip lines, and suspended rope bridges. Take pleasure in the details of hand-split oak shingles, thatched roofs, and cedar tongue-and-groove interiors. Made of sustainably sourced materials, Blue Forest's magical sanctuaries fit snugly between trees and branches—often incorporating them into the building itself—and sit lightly on the land. From a child's tree house inside a secret garden to party venues for teenagers and adults, this book details 28 imaginative tree houses, some of them accompanied by site plans and drawings. Whether the dwellings on each page are simple or designed to house a spa or home theatre, this beautiful book will inspire readers to reconsider their own garden's possibilities for relaxation and play.
