Form follows function as dual gallery halls lead from formal areas to split sleeping quarters in this Prairie house plan adaptation. At the heart of the house plan, the grand-scale great room offers a raised-hearth fireplace framed by built-in cabinetry and plant shelves. Traditional formal rooms blend into more open, casual living areas through classic archways. Open planning combines the country kitchen with an informal dining space and adds an island counter with a snack bar. A lavish master suite harbors a sitting area with private access to the covered pergola. The secondary sleeping wing includes a spacious guest suite with an angled whirlpool tub. A home office or guest bedroom offers its own door to the wraparound porch. Related Plan: Need less space? See house plan 81312W (2,626 s.f.).
