Rebecca Davis Tulman of Coldwell Residential Brokerage has listed Unit 3F at 398 Beacon St., a one-of-a-kind home with views of this iconic neighborhood and Charles River, for $1,825,000.

Being a homeowner on Beacon Street in Back Bay comes with many perks. The location is practically perfect - only one block to Commonwealth Avenue and the Mall and two blocks to Newbury Street. And living in one of the city’s classic 19th century Victorian brownstones is an opportunity to be part of this area’s long-standing reputation for style and grandeur.

When that “opportunity” is a 1,533 square-foot townhome with two-plus bedrooms and two full bathrooms on the waterside of Beacon, the excitement level ratchets up exponentially.

The thoughtfully designed floor plan allows ample privacy for personal spaces and a stunning transitional space into the common areas. That in-between area is unique and clever with an emphasis on beauty. It all happens as soon as the door opens to this residence.

Uplighting tucked into the lavish triple crown molding draws attention to the barrel ceiling in the long foyer hallway. It’s at least a 12-foot stretch. Here, gallery-like walls are ready for favorite works of art for residents and visitors alike to peruse along the way while a lighted niche at the end of the corridor is ready-made for sculpture or installation artwork.

Although the large living-dining room is thoroughly modern, the “space” reflects 19th century sensibilities in terms of dimension, scale and details, and it all works. It does so beautifully, too.

Three full-glass pane windows (these are about eight-feet high with custom shades) in a wide bay command attention, not only for their beauty, but also for the north-facing view that includes the Charles River. Extra-wide casings around the windows produce a framed triptych-like effect of the captivating scene.

The ceiling, which is just shy of being 12 feet high, is rimmed with lavish triple-crown molding. Extra deep bump boards with detailed trim that showcase glistening oak floor boards are additional period features that help create a sense of timelessness. A bump out large enough for a chest/table/etc. is adjacent to the marble fireplace with decorative carvings on the surround.

Enjoying the best of all possible open-flow configurations, the dining area is fully open to the living room, yet has its own designated space - and lots of it. An extraordinarily wide archway separates the two spaces.

The dining area that can accommodate eight or more comfortably, has a large and lighted niche that is ready-made for a server/credenza or even a china cabinet. Two additional lighted niches on another wall stretch almost to the ceiling and are mirrored. Whether used for a china cabinet or art displays (reflections from the mirrors add visual interest), the amount of storage space is incredible. The dining room has its own double-hung four-over-four window, too.

The U-shaped kitchen is more than a study in efficiency. An ample amount of good-looking cherry cabinetry installed to the ceiling with under-cabinet lighting is accented with a glittering backsplash of mini-glass and stainless steel subway tile. Stainless steel appliances that include a Bosch dishwasher, KitchenAid refrigerator, GE electric stove and microwave add extra sparkle. The granite countertop affords excellent prep space.

A nearby full bathroom that is tucked under a rounded archway has a tub/shower combination. An oval sink in the single vanity is under a unique bay-like mirror.

Although this residence has room to spare, every square foot is well used. Consider mini-office space just outside the bedrooms in the “private” wing. At least six feet long and more than desktop computer-wide, the credenza-like desk has a pullout keyboard tray and a substantial amount of file drawer space in addition to overhead cabinets.

A nearby closet is handy for extra storage and/or coats as this is only a couple steps from the “front” door.

The elegantly proportioned sleeping chamber in the master suite has numerous highlights including a wide bay that has three oversized windows (these south-facing beauties look out over Beacon Street) with plantation shutters and accented with shadow box paneling.

The fireplace is another stunner. The extra-wide marble mantel seems to be designed for art displays with Art Deco style carvings as unique accents. Two niches on each side of the fireplace are large enough for dressers/bureaus.

Triple-crown molding and deep detailed bump boards showcase beautiful hardwood flooring in this king-bed size room. An Electrolux full-size stacking washer and dryer are out of sight behind closed doors.

Two double closets are in the “hallway” leading to French doors that open into the en suite bathroom. The tub/shower combination has a tile surround. The bay-window-like mirrors over the sink (these are curved) may be atypical, but they are intriguing.

In the nicely sized guest bedroom, plantation shutters on the oversized window with shadowbox paneling underneath are elegant “finishing” touches, carpeting a soft one. Installing a sleep sofa, day bed or even a Murphy bed could increase the potential uses. A deep single closet is another convenience.
