“This is not your typical South Boston duplex,” said Tia Zaferakis of Jack Conway Cityside, listing agent for the freshly painted 1,710-square-foot, three-bedroom Unit 1. “It has full-bridge windows, not little tiny windows that make people feel like they're 'way down below.' ”

The two-unit renovation of 694 East Fifth St. in South Boston in 2000 went beyond reinventing a century-old three-decker for the new millennium. It showed how timelessly adaptable the freestanding three-decker form can be to the homebuyer’s present-day preferences for multidirectional light, open-concept living, good-sized bedrooms and baths, generous outdoor space, privacy, and, above all, a lower level that doesn’t feel like a basement.

“This is not your typical South Boston duplex,” said Tia Zaferakis of Jack Conway Cityside, listing agent for the freshly painted 1,710-square-foot, three-bedroom Unit 1. “It has full-bridge windows, not little tiny windows that make people feel like they’re ‘way down below.’ ”

Nor will you feel like you’re “way up above” or “way in the back,” thanks to Unit 1’s street-level and lower-level location, as well as the separate entrance that opens right into the front-to-back living-dining area, which offers another rarity for a duplex or three-decker.

“You have two gracious-sized living rooms – two very nicely done sitting areas,” said Zaferakis.

The front living room benefits from the bay window for a bump-out sitting area which floods in light and street views. A wall treatment of contrasting hues of brown, divided by a chair rail, unifies all three spaces into one elegant entertaining arena. Side-by-side beside the entrance is a sizable coat closet and a powder room with an oval pedestal sink.

The contiguous second living room invites you to sit before a gas fireplace, framed by a classic paneled mantel that is flanked by the vintage bookshelf built-ins with milled edges and paneled ends. The mantel and built-ins extend from the wall for a sculptural effect.

This space continues into the dining area, which seats 10 to 12 people comfortably and has a stylish chrome chandelier.

For al fresco dining, a double French door opens to a private deck planked with Trex composite decking, blending woodgrain beauty with low-maintenance resistance to pests, rot and stains.

The deck steps down to the master bedroom’s private patio and the two side-by-side parking spaces in a lot bordered by shrubs, flowers and ornamental trees.

The dining room flows right into the kitchen via a granite island for food service and conversation convenience. The kitchen is a model of open-plan efficiency. Two granite wall counters incorporate all paneled cabinetry and stainless appliances in an L form.

Along the longer counter, a Bosch five-burner gas range with a microwave/vent is between the Bosch dishwasher and the Fisher & Paykel refrigerator with a bottom freezer drawer. An angled sink with a gooseneck faucet anchors the counter’s opposite end by the laundry closet. Below the smaller counter is a KitchenAid trash compactor.

Unlike a typical L-shaped kitchen counter, this one’s separation into two allows passage to the laundry closet with a Bosch stacked washer/dryer. Another closet is in between the shorter counter and the oaken stairway to the bedroom level.

“You go down a very sizable stairwell. You then have a nice open hallway that leads to two bedrooms on one side, a large guest bath with a whirlpool tub, and a master bedroom with an en suite bath with another whirlpool,” said Zaferakis. “It’s a true three-bedroom unit with very gracious-sized rooms that are not tiny like an office.”

This is evident upon entering the left-hand master bedroom, which four windows generously brighten. The smaller windows are for the bed/dresser room below while the larger ones look out onto the sunken patio – accessible through a French door.

The deck above and the high concrete walls bring cool intimacy to the patio, which can be an outdoor workout space or an extension of the deck’s entertaining space – courtesy of the stairway that connects them.

The master bath boasts a faux Carrara marble-tiled whirlpool tub/shower, a bullnose granite vanity with a gooseneck faucet, an Italian tumbled-tile floor and an alcove of linen/toiletry shelves. Beside the bath is a walk-in closet.

The guest bath is just as spacious and stylish. The classic white vanity greets you with a classically framed mirror with milled cornice and bell lights. Faux Carrara marble tiling surrounds the whirlpool tub/shower. A gray/brown faux granite-tiled floor adds a neutral touch. A corner cabinet provides additional storage/counter space.

The adjacent second bedroom is like the master in size and the front living room in space and light - kudos to the bay window. It also has a contrast of light brown wall hues and the large windows, which let in so much sun that one upper wall was painted dark blue to mitigate the light.

The third bedroom’s single window allows a generous wall area for a deluxe workstation and bookcases for a large home office or library.

Both bedrooms have large custom closets. In the hall are two additional closets – one under the stairway.

The location is as exceptional as the layout.

“It’s central to the east side, so it’s a short walk to the beach, the walking trails, the parks, the trendy new restaurants, shopping and four bus lines,” said Zaferakis.

It is but a few blocks away from South Boston’s stellar attractions, including Castle Island, Joe Moakley Park and three beaches. Down the Harborwalk are UMass-Boston and the John F. Kennedy Presidential Library and Museum.

Offered at $1,275,000, Unit 1 at 694 East Fifth St. brings the three-decker’s blend of spatial economy and light-filled expanse to a new level.

“Very rarely do you get such engaging living space,” said Zaferakis, who may be contacted at 617-699-6268 or tzaferakis@jackconway.com for a showing - by appointment only.
