A unique new house in Old Greenwich that is shingle style on the outside opens up — literally — inside. A Nana Wall System, consisting of L-shaped glass walls that fold like an accordion, open much of the living room to the expansive views of Long Island Sound.
Set on a double lot of two-thirds of an acre, the almost 9,000-square-foot residence offers views of either the Sound or Greenwich Cove — in some instances both — from nearly every room.
Priced at a little less than $8 million by the listing broker, Paul Pugliese of Greenwich Land Co., the house has a collection of the amenities of today: an elevator to all four floors, six fireplaces, garaging for three cars, front and back stairways, his-and-her master baths, a generator and luxurious detailing throughout.
The three-story entryway, topped by a cupola far above, opens to a large living room with the walls that open and a fireplace surrounded by deep gray marble lined in brick. An oversized extension bay on one side has five windows that provide water views in two directions.
Beyond the living room is a mahogany porch with a fan, an outdoor fieldstone fireplace and columns holding up the beadboard ceiling, with a stone terrace beyond.
The dining room with coffered ceiling opens to a terrace with a built-in grill, and the library is covered in dark cherry and boasts a fireplace and another coffered ceiling.
The guest powder room has a half-moon sink with a hammered nickel bowl set in white onyx and a marble floor in a cross-hatched pattern. The family half-bath has a large oval window and custom built-ins.
The kitchen by Christopher Peacock has pairs of 48-inch SubZero refrigerator-freezers, Bosch dishwashers, and sinks, including one in the huge island. There’s a built-in microwave, and the professional Viking stove has six burners and a grill. One wall holds cabinets designed to look like an antique multi-doored refrigerator, with the appropriate nickel hardware, and there’s a waterside breakfast area. Backsplashes are crafted of marble and glass tile.
The adjoining great room has a 12-foot-high wall of glass overlooking the Sound, as well as a fireplace, and nearby is the home management office with a long, built-in desk. Access through a side entrance enables easy delivery of groceries to the room-sized pantry, and there’s a fitted mud room, one of two.
The master suite occupies its own large wing on the second level, with bedroom, sitting room, dressing rooms, his and hers baths and a roof deck.
The waterview bedroom has a fireplace and beamed beadboard ceiling, and the sitting room, with a wet bar and custom TV cabinet, opens to the Sound-side roof deck.
In a bay, her bath has a dramatic free-standing oval tub filled by water descending in a stream from the ceiling. The marble floor is radiant heated, and the frameless steam shower has a number of shower heads, including one that simulates rain. Peacluding one that simulates rain. Peacock designed the custom vanity that includes a new-to-me towel-heating drawer.
Her pastel dressing room has a large square island with multiple drawers, a make-up table, two window seats overlooking the cove and even separate shoe drawers. His bath, with body sprays and a rain head in the steam shower, along with heated marble floor, adjoins his more masculine dressing room.
On the other side of the second floor are a laundry room, with sink and beadboard cabinets and drawers, four bedrooms, four marble-floored baths, each in varying soft tones, and a family room with vaulted ceiling, skylights and a wood floor in a bowling pin pattern.
The third level has a guest suite with heated-floor bath with a skylight over the shower,  a sitting room and a Juliet balcony. One room has a rustic skip-sawn oak floor with natural wood patterns and a plan for extensive wine storage. One end of the family room with fireplace is a triangulated, glass-paneled atrium, and there’s a narrow window that runs completely through the fieldstone chimney for another view of the water. Inside, there’s a Peacock-designed wet bar. An outside balcony, protected with stainless steel railings, offers views as far as Stamford Lighthouse.
Up the floating staircase is the fourth-level semi-circular roof deck of more than 200 square feet with stainless steel railings and access to the cupola.
Throughout the interior are rift-and-quartered, six-inch white oak plank floors, high ceilings and custom detailing. Rift floors are crafted from lumber with larger than normal growth rings and a vertical grain, and quarter-sawn wood inhibits shrinking, swelling and warping.
The solid mahogany exterior doors have white bronze hardware, and hardware everywhere else is polished nickel. There’s Smart House wiring and controls, a roof of cedar shingles and an Energy Star rating.
A stone wall runs along the road, and a covered, stone-pillared porch faced with hydrangeas and boxwood crosses much of the front facade of the house and wraps around one side into a porte-cochere. The driveway with double entrances is topped with oyster shells originally from New Hampshire, according to Pugliese.
