Encompassing the parlor level and second floor of the building that dates back to 1899, this brand new home, which is 25-feet wide, has three bedrooms, three full bathrooms, one half bathroom and 3,384 square feet of living space. It is listed by Glenn Forger of Olde Forge Realty for $9,300,000.

Imagine a restoration/renovation project, not just down to the studs, but right down to the pilings - 61 of them set 60 feet deep - and then topped with steel construction. That’s the story behind, above and below Unit A at 75 Beacon St. This is a magnificent townhome on the Flat of the Hill directly across from the Public Garden.

Encompassing the parlor level and second floor of the building that dates back to 1899, this brand new home, which is 25-feet wide, has three bedrooms, three full bathrooms, one half bathroom and 3,384 square feet of living space. It is listed by Glenn Forger of Olde Forge Realty for $9,300,000.

The front-to-back parlor level, which has as open concept living-dining room, is filled with extraordinary features, details and amenities. One of the most memorable is the floor-through sight line that stretches from the open-concept living-dining room past the kitchen into a bonus room at the back of the house. The effect is amazing.

Countless architectural features command attention, too. One is the unique front boxed window, which has multiple glass panes within individual windows plus a three-window section with a huge eyebrow transom that was restored off-site. Mirrors installed on the end side panels reflect natural light into the living room, along with gorgeous views of the Public Garden and Beacon Street.

Soaring 11-and-a-half-foot high ceilings that drop to 10 feet on the second floor are surrounded by custom milled triple-crown moldings that exemplify 19th century craftsmanship with a contemporary edge.

Paneled wainscoting and deep bump boards accent five-inch-wide quarter sawn oak floorboards that are throughout the home. A custom mantel surrounds the gas fireplace.

A 21st century interpretation of a classic built-in china cabinet with interior down lights and glass front doors over four drawers stretches to the ceiling in the huge dining area that seat a minimum of eight people. Two cased openings - each with multi-glass pane transoms - separate a 10-foot long wet bar space that is between the dining room and the kitchen.

The bar includes a wine fridge, stainless steel sink, Sub-Zero refrigerator drawers and an ice maker and custom cabinetry with under mount lighting and interior down-lighting.

Matching cabinetry is only one of many features that create an exceptionally stunning, yet functional kitchen. Wolf stainless steel appliances that include double ovens and gas stove top plus a Sub-Zero refrigerator with integrated panels address practical needs.

Two stainless steel sinks (one is in a mini-Butler pantry space with a secondary dishwasher while the other overlooks Bryon Street) increase the efficiency of this room.

The extended center island with a deep countertop, on the other hand, is both beautiful and practical with a microwave oven and the ability to seat four people. By the way, seats at the island face out to the living room and include park views.

A huge back room just off the kitchen is far from ordinary, too. White shiplap on the uniquely shaped soaring ceiling is one unforgettable feature as are two double hung windows. These six-over-six statements have almost 18-inch square panes of glass.

However this back room is used - office, breakfast nook, etc. - the bonus is that even from here you can see straight through to the Public Garden.

The elegance that is paneled wainscoting throughout the entire stairwell and in the second-floor corridors, plus deep double crown molding and bump boards, doesn’t end at the bedroom doors on this level. The bedrooms, two of which have en suite bathrooms, are understated beauties.

The master suite, of course, is another outstanding example. Consider that at 23-feet wide, the sleeping chamber is almost the width of the unit. Three oversized bay window areas in this south-facing room, each with multi-glass pane windows, have mirrors on the “side” walls that reflect both natural light and the amazing Beacon Street views.

A gas fireplace, flanked by custom built-ins at one end of the room, is suitable for comfy seating. It is a thoroughly modern sitting room/parlor. The rest of the space easily accommodates any desired amount of bedroom furniture.

On the other hand, well-planned custom inserts in the walk-in closet dressing room that is almost half the size of the bedroom could eliminate the need for bureaus, chests, etc.

Luxurious finishes such as large marble hexagon floor tiles and oversized marble subway tile wainscoting in the en suite bathroom are complemented by equally stunning amenities that include a soaking tub with a stainless steel surround and a step-in shower with three sprays (a rain head, regulation shower head and hand-held body wand) within a frameless glass enclosure. The marble subway tile surround stretches to the ceiling.

The wall-hung Kohler commode has its own frosted frameless glass enclosure and the marble-topped vanity has two sinks.

An exceptionally wide six-over-six window (the panes are almost 18-inches square) is an instant focal point in the second bedroom suite. A king-size bed fits comfortably in this chamber that also has a deep and lighted walk-in closet.

Marble floor tiles in a basketweave pattern are a nod to the building’s past, but the step-in shower with two sprays (one is a hand-held wand) in a frameless glass enclosure with a subway tile surround is strictly modern. The sink is by Kallista and the commode by Kohler.

A wide built-in bench (with storage) - under an extra-wide six-over-window - between two custom floor-to-ceiling wardrobes combines old-world charm with practicality in a spacious bedroom (or not) at the back of the residence overlooking Byron Street. Great as guest space, a private office or even a playroom for the younger set, this room has easy access to a full bathroom just down the hall.

This loo with a step-in shower in a frameless glass enclosure and marble floor tile in a basketweave pattern is adjacent to laundry facilities with a full-size Electrolux washer and dryer.

That this home comes with outdoor space that is well-planned with exceptional amenities is a given. The private roof deck, which is at the end of a regulation staircase, is big - in fact it has more than 650 square feet of casual living/entertaining space with water and electricity. Copper accents on the downspout and window lintels gleam in the sunlight.

Although tile flooring that lets water drain is technically impressive, the outdoor kitchen unit is the star. The DCS Fisher Paykel unit includes a grill, refrigerator and a sink plus adjacent workspace. Of course, rooftop views of the neighboring homes and Boston landmarks are fascinating any time of year.

Among the many perks that come with this property, the availability of concierge service, private elevator access from the first floor to the heated garage, and a private storage room is guaranteed to be a favorite.

Even if you’ve pulled in front-end first, an inlaid turnstile turns the car around to face the heated brick paver driveway so you can drive right out to the street. This home has two parking spaces: one inside; one outside.
