Most townhomes in the sizzling South End have fascinating histories going back more than 100 years. The back story for this property is equally interesting, albeit unique: it’s not old, and it has an exciting future. This building at 82-84 East Brookline St. was constructed from the ground up in 2002.

Unit 6 is a spacious, bright and airy penthouse duplex that is filled with 21st century amenities, yet thrives in any era.

Oak flooring (found throughout this unit) and curved double crown molding that accents the wide bay with two oversized two-over-one windows create an “Old World” touch in the spacious living room.

Another window is in an adjacent bump out. Flanked by two built-in bookcases with open- and closed-shelving (one side has built-in desk space), the gas fireplace with a prettily detailed mantel becomes an instant focal point.

A deep coat closet with custom inserts and a hidden cubby under the stairs to the second level provide a substantial amount of storage. A large half bathroom with Kohler fixtures and a marble tile floor are also on this level.

The eat-in kitchen is more than simply big. A built-in banquette seats six-plus people comfortably while the table doubles as extra prep space – a lot of it, too.

An adjacent credenza with a butcher block counter works as a server when dining or a dry bar when entertaining. An overhead cabinet that stretches to the ceiling has glass-front doors.

The “working” part of the kitchen is a sleek U-shaped galley with black granite countertops and stainless-steel appliances that include a Bosch dishwasher and Samsung refrigerator. A mirrored backsplash adds depth, sparkle and maximizes the benefits of under mount lighting. Double crown molding is a finishing touch. The kitchen also has a deep and lighted pantry closet.

A full glass pane door opens to a private deck and, for added convenience, to parking behind the building. Drive in and come through the back door directly to the unit.

Like the living room below, the master bedroom is huge. A three-window bay that starts about three feet from the floor provides some privacy without obstructing light flow. Moreover, this area is large enough for a comfy chair or two. Closet space in the king-bed size sleeping chamber is abundant. Two oversized single closets have custom inserts.

The second bedroom – for guests or family – is almost identical in size to the master - as in very big. Strategically placed windows on two exposures maximize the flow of natural light. An extra-deep and extra-wide double closet that is essentially a walk-in affair is fully customized with various inserts.

The full bathroom on this level is both efficient and beautiful. Marble is the finishing material used in the surround of the tub/shower ensemble as well as on the floor and long vanity countertop. Elbow room is plentiful. The commode has its own private room.

Laundry facilities (a full-size, stackable Whirlpool washer and dryer) are in the hallway.

In addition to looks and location, this in-town residence has another exceptional feature: a new rooftop deck. Fully equipped with water, electricity and gas (for a grill, of course), this grand-sized outdoor space has a commanding rooftop view of the neighborhood to the Prudential and Back Bay.

Getting to this urban yard is easy. A regulation staircase (forget about navigating spiral staircases or narrow ladder-like steps) is the pathway to the great outdoors. It’s wide and bright, too, thanks to the full glass pane door that opens to the roof.

Location-wise, the future is exciting for this home. It’s only a block from Exchange South End - a $1 billion-plus project on the site of the now-shuttered Boston Flower Exchange on Albany Street. This development that includes a 1.6 million square-foot life sciences and technology campus – near Boston Medical and Boston University Medical centers and the SoWa neighborhood – plus pedestrian-friendly open space – Albany Green – is in the works. An endeavor of this magnitude not only makes this the largest development in living memory of the South End, but brands this opulent home a fantastic investment.
