The Allandale House. Designed by William O’Brien Jr., the assistant professor of Architecture in Cambridge, Massachusetts, this unusual vacation house plan is an A-frame house in the forest that stands out among the trees.
Backyard:the tree was diseased. the trunk was still "good". they built the ultimate treehouse using reclaimed materials. this is not your ordinary tree house.this is a BIG KID tree house. i am in LOVE! someday, i will have a cool treehouse, too!
