Stein's décor scheme was inspired mainly by her home's lofty architecture. The high ceilings, white brick walls and exposed iron beams begged for a visually interesting interior. "I wanted to keep it light, bright and modern but also bring in an interesting mix of furniture," Stein says. Since all of the loft — except for her bedroom — is one great room, it was important for her to pay attention to floor plans and arrange the furniture in a logical and comfortable way. "Even the best furniture won't look good if it's positioned wrong," she says. "I had my furniture laid out three ways before I found the best arrangement."
