Knowing that they were looking to design a loft-like environment, the couple kept to an open layout for the majority of the living space. One of the most fantastic features of the space is a bank of clerestory windows that flood the interior with seemingly endless amounts of daylight. Originally added back when the building served as an artist studio, Weiss and Carpenter agreed that keeping them was a must. "The only original part of the house is the ceiling and the existing skylights and clerestory," Weiss describes. "We basically changed everything else." The ceiling compliments the contents of the environment, but also continues the story of the homeowners' design philosophy. "We loved the original wood and steel ceiling, including steel beams forged at the Carnegie Steel Works," Carpenter explains. "In coming up with our design approach, we wanted to reflect some of the previous uses of the structure ... Keeping elements from the past not only interested us aesthetically." he says, "It was important to us to reuse structures and objects in ways that are close to their originally intended use."
