This clean, ultra-modern Chicago home is the former residence of the very architect who designed it. Meticulously crafted in a particularly spare design, its clean lines, built-in book cases, and use of natural materials pay homage to minimalist building architecture. Seamless floor-to-ceiling windows let in the light and bring the outdoors inside, a sensibility that informs the sustainable design. Four bedrooms and three spa-like bedrooms unfold over 4,000-plus square feet. View property.
