Chicago-based home builder Ranquist Development executed this amazing city house renovation and they built a bit of the great outdoors right in. This modern triangular-shaped house plan features a three-story interior courtyard, which adds architectural interest while flooding the space with natural light. The unique footprint of this 8,600-sq.-ft. custom home provides for a contemporary open-concept layout. On entry, a landscaped atrium leads you to the main level, where the kitchen features a two-storey glass wall that opens to the backyard. The fully functional double-height windows have an industrial edge to them, complementing the exposed brick, ductwork and rustic wood beams throughout. The kitchen leads into the living and dining room, media room, mudroom and out to the attached garage. Upstairs are three bedrooms and an open loft space that leads out to an adjacent deck. The third floor houses the sweet retreat – a boutique hotel-style, glass-enclosed penthouse surrounded by the rooftop deck. The basement level rounds out this house, with a theatre, spa bath, guest room and playroom space. This spacious multi-level home is awesome for entertaining and family life. Ranquist Development.
