Overlooking the Rose Fitzgerald Kennedy Greenway along the waterfront is a one-plus bedroom corner unit at 110 Broad St. in the newly constructed 12-story glass, steel and brick development called the Boulevard on the Greenway.

Jillian Reig and Stephen Losordo of Compass are marketing Unit 401, a 1,410-square-foot condo, at $1,849,000.

This home is one of 36 residences in this boutique mixed-use development, completed about a year ago.

The new construction incorporated part of an 1805 warehouse designed by Charles Bulfinch, the same architect who designed the State House 10 years earlier.

Essentially, two of its four-story exterior walls were preserved. New Boston Ventures developed the building, which was designed by Finegold Alexander Architects.

A tall glass door, flanked by windows, opens into a soaring lobby, tiled with Ann Sacks porcelain, anchored by a wide concierge desk. Next to the reception area is a high wall featuring a creative design of preserved vegetation, like mosses, referencing the nearby Kennedy Greenway.

Around a corner are two elevators to the residents’ common spaces and the condominiums.

Unit 401 has an entry hall that leads into the expansive open living/dining/kitchen area filled with light. A coat closet, a laundry closet with a Whirlpool stacked washer/dryer and a stylish half bath are on one side of the passageway. The other side is gallery space for artwork.

The L-shaped hall continues toward the main living area, but before that is a door to the en suite bedroom facing a good-sized area with a double-door closet. Losordo says this could serve as a den or a wall could be added to create a nursery.

The main living space, with its wide-plank hardwood flooring with a sand stain, has a nine-foot ceiling and nearly floor-to-ceiling glass on two exposures.

The gas-ribbon fireplace on one wall is a nice feature in the living area, which also has a glass door that opens onto a pleasant balcony. From this perch are views of the inner harbor beyond Rowes Wharf and a panorama of the Greenway to the North End. The historic Custom House tour is visible, too.

A long center island topped with white quartzite delineates the bright kitchen from the living room and faces the large windows. Beneath the island with a deep stainless steel rectangular sink are a Thermador dishwasher and Thermador microwave.

Gleaming European-style lacquered white cabinets line the interior wall that holds a convection oven. The Thermador double-door refrigerator with a bottom freezer has a matching glossy white finish. The Thermador five-burner gas cooktop has a retractable Broan hood.

At the corner of the living area overlooking the Greenway is room for a dining table and chairs. As an alternative, said Losordo, the niche could be set up for a home office.

The exterior wall of the bedroom is part of the Bulfinch component of the building, and its two new windows replicate the size and shape of the originals with their multi-panes. The en suite bath, finished with striking striped porcelain tiles, has a double vanity topped with white quartzite, a glass-enclosed shower with a rain showerhead, and a dual-flush toilet, like that in the powder room.

On the second floor of the building, within the Bulfinch walls, is the residents’ clubroom/library where space has been earmarked for a caterer’s kitchen and dining area.

And on the third floor are a fitness room with gym equipment and a pet-grooming spa, where dog owners can shampoo their pup.

A unique feature of this development is the fully automatic parking system, Park Plus, a computerized system that allows residents to call for their car from their mobile device by punching in a code. Access to the 48-car underground garage will be from Wharf Street. The purchase of Unit 401 includes deeded parking.

What is particularly convenient is the easy access to the main highways – Routes 93 north and south and Route 90 – as well as living in a walkable neighborhood, close to South Station and Chinatown and to the North End as well as the amenities along the Waterfront.
