This case study project investigates how to compose and construct a hybrid drawing. Several drawings are combined together for a hybridized representation of RoTo Architects’ Carlson Reges House. The pool in the house serves as a datum tying the individual drawings together. Furthermore, colors are used to delineate the different types of drawing: the red represents a section while the black shows a plan corresponding to the section. Both drawings are correlated by the pool in section and the pool in plan. While acknowledging its urban industrial site, the house emphasizes the importance of sustainability by reusing materials found on site; for instance the swimming pool is literally an old gas tank found on site and cut in half for a lap pool in the house.
