Tree-houses can be a romantic fascination for children and adults alike. We have an innate physiological bond with trees that may very well stem from a genetic memory of our ancestors reliance on these living giants. Psychologists have shown that we are drawn to trees that are climbable and provide good opportunity for broad surveillance, probably based on early survival needs. “The idea of building a small refuge in the trees seems to be one that man has entertained since the beginning of his existence……In certain cultures of the South Pacific, entire populations once lived among the trees……Records also document observation bridges in Japan, luxurious platforms in Persia and classical Rome, and a popularized version of the tree house in Victorian-era Britain” (From TreeHouses by Alejandro Bahamon, 2007). Tree houses come in all styles from an eclectic structure pieced together with found materials to a refined architectural design built by professional craftsman. Many people think of tree houses a place for children to explore, exercise and imagine. But today, tree houses are being built as home offices, guest rooms and even entire living spaces.
