Hideaways and Studios -- TreeHouses are not just for kids anymore. In urban backyards or on forested acreage, the majority of our work has been for families who are looking for more space and happened to 'look up'. A playroom for the kids, art studio for mom, cigar room for dad, or a game cabin for the whole family, this group of treehouses under 400 sq. ft. are as diverse as they are fun. Everyone is allowed in these tree houses!
