Twins: Houses in Five Parts are two home proposals found on The Fancy. The designs were created for brothers looking to build two nearby vacation homes for their families. O'Brien gives detailed theory to explain his polygonal approach but the nitty-gritty is too in-depth for this website (read more background here). The houses look beautiful with their modern lines and open spaces, providing a truly blissful retreat. The over-sized windows make privacy far from guaranteed but when you're in the middle of the woods, only forest animals (and the occasional stalker) will have the opportunity to sneak peeks.
