Old versus new. American desert and French Provincial. Rustic stone juxtaposed with smooth plaster and tiles. Inside reaches out through walls of steel and glass and climbing through it all is a sinuous staircase of wood and iron. Rough luxe versus sophisticated modern living. At its heart this rambling stone edifice is first and foremost a gathering place for family and friends. Private residence #4 at Silverleaf Scottsdale, Arizona OZ Architects.
