Jonathan and Sarah Rapaport traded New York City for a life in Lincoln and a 4,000-square-foot mid-century-modern home in the Deck House style — with post-and-beam construction, a tongue-and-groove ceiling, open floor plan, and lots of glass.

BEFORE: For the redesign, the Rapaports turned to Colin Flavin, principal of Boston-based Flavin Architects, who is married to Jonathan’s sister. “The previous owners celebrated the woody end of the design spectrum,” Flavin says. “Jon and Sarah wanted something less rustic.”

The redesigned kitchen features streamlined gray cabinetry and a Heath ceramics backsplash (which Jonathan first saw in a Spider-Man movie and tracked down).

BEFORE: Flavin removed a sliding barn door to enlarge the dining area, and reworked the kitchen walls to create an airy but separate space, complete with pass-through window and pocket door.

BEFORE: The original interiors skewed darker and more rustic. The owners chose to remove the flagstone and old oak floors and replace them with cerused oak in a bluish-gray tint.

This bathroom has marble tile floors and holds a freestanding tub by Wetstyle and custom vanity of cerused oak by Oak Tree Woodworking in Winchendon.

Post-and-beam construction and plenty of windows are hallmarks of the Deck House style. By reworking the colors, the Rapaports, along with Flavin and Howard Raley, the project architect, transformed the house into a sleek abode that looks very this century while retaining its mid-20th-century roots.
