First time on the market since 1968! This fantastic 1955 MCM hillside ranch in North Barrington's highly desirable Biltmore subdivision sits on a double lot overlooking a creek at the bottom of a ravine, and is in just a wonderful, quiet, interior location. Designed by William Cooley of Stade & Cooley Architects for his own family, the home features a hillside ranch layout with classic mid-century modern elements. Upstairs you'll find a welcoming foyer that offers views through the wall of glass on the far side of the living room out to the ravine beyond. An open kitchen / dining area continues with the theme of the house, featuring suspended cabinets, volume ceilings, exposed beams, wood paneling, and so much glass to let in natural light and views of nature throughout. The living room has built-in bookcases and a feature fireplace made of stone, with a massive copper hood and floating hearth. A sunken screen porch off of the dining room is perfect for enjoying beautiful days and even more beautiful views. The Primary Suite has a private bath with dual sinks, travertine counter top and original, vintage mosaic tile. Two more bedrooms, another full bath, and the three car garage complete the main level. The lower level features a rec room with bar area, another bedroom with abundant closet space, a full bathroom with walk-in shower, a "twin bedroom" with accordion door that's currently being used as dual offices, and a den with Roman brick fireplace - plus the laundry & utility room. Highly rated Barrington schools, convenient location between both Barrington and Lake Zurich, and so much more. This is a very rare opportunity to get into a beautifully designed home with lots of original character in a very special location!
