The third home in this week’s roundup of Massachusetts’ most expensive home sales hides sleek modernity behind a facade from the late 1700s. The centerpiece of the 2018 renovation is a three-story staircase with glass railings that connects the main living areas – including a large kitchen with a marble waterfall counter – to a main bedroom with peaked ceilings and an adjoining dressing room. A parlor with striking, blue, coffered paneling and a detached studio round out this blend of the contemporary and the traditional.
