Built c.1867 for Attorney William Everett, son of Massachusetts Gov. Edward Everett, this stately French Academic townhouse was reconverted to its original single-family status by The Holland Companies in 2011.

Towering above its neighbors, 89 Marlborough St. readily gives away its great soar of space inside: six full levels of living with ceilings as high as 13 to 16 feet, all elevator-accessible. Furthermore, its “corner” location, courtesy of an open court abutment, divulges its three sides of exposure - a rarity in the Back Bay.

But not readily apparent from the street are more spatial rarities: a finished basement with home gym and craft room, a two-level roof deck with incomparable skyline views, a heated two-car parking area in the rear, and a Beacon Hill-style “hidden garden” in the front, the first harbinger of the quiet privacy all of the spaces afford.

This gives the buyer 7,607 square feet of space for a growing family, dressed to the hilt with the historical elegance of its era. The five full baths are all en suite with the five bedrooms for premium privacy for the whole family.

The ground-level entrance – a convenient alternative to the strenuous stoop – begins the refinement right away with a checkerboard tile floor vestibule, followed by a gracious hall tastefully trimmed in paneled wainscoting and crown molding. At left is a formal reception room with ample light from the garden windows.

Ahead is a classic turned-baluster staircase with spiral newel post, followed by the paneled elevator and the au pair/in-law suite. The latter contains an eat-in kitchenette with black granite counter and paneled Shaker-style cabinetry and a full shower bath with basket weave-patterned Carrara marble tile floor and white Paris-Métro wall tiling characteristic of most of the baths.

From the sizable bedroom, two double French doors exit to a bluestone patio and the rear parking, which is paved in herringbone brick. A long mudroom with a bluestone tile floor and a wall of coat hooks, shoe-removal benches and upper shelves also access the parking.

On the second floor, the formal dining room features paneled wainscoting, custom green wallcovering hand-painted in leafy designs, corner exposure and one of six fireplaces with salvaged historic marble mantels.

A double French door opens to a front Juliet balcony with cast-iron railing. Off the central hall is a quaint powder room with hand-painted leafy patterns on the porcelain sink and makeup mirror.

The chef’s kitchen in the rear is garnished gourmet-style with a black granite island counter built in with a sink, dishwasher and microwave; a black granite L-shaped running counter with a double sink and a Viking six-burner gas range with a grill; a coffered ceiling with paneled beams; and paneled white Shaker-style cabinetry.

Built into the cabinetry are separate oversized refrigerator and freezer units and a second dishwasher. Also in the kitchen are a black granite “home central” desk and a butler’s pantry with Viking catering oven. Paris-Métro white-tile backsplashes complete the composition.

The haute couture continues on the third floor with the wood-paneled formal library. Its scholarly enrichments include a coffered ceiling with molded rosettes and egg-and-dart moldings, a hand-nailed parquet floor inlaid in a crisscross pattern, a classic fireplace carved with Grecian urns and scroll brackets, a wet-bar with black granite counter and mirror-backed glass shelves, and a full-wall bookcase with track-run stepladder. Twin French windows open to twin Juliet balconies in the rear.

Past another powder room with hand-painted floral designs on the porcelain sink, shelf and mirror is the formal living room. The bowfront lets in generous light and city views. The yellow wall treatment brightens the space and the sole remaining marble mantel, original to the house, is gracefully carved in leaf patterns.

The floor-through master suite occupies the entire fourth floor. The master bedroom with a fireplace has blue wallcovering, hand-painted in flower-cluster patterns. A tray ceiling heightens the space.

Two walk-in closets precede the five-piece master bath, where Carrara marble permeates the wainscoting, benched shower, two-sink vanity, built-in makeup table, and basket weave floor to give a sense of palatial pride to one’s ablutions.

Finishing the formalities are an oval clawfoot tub with cradled hand-held shower, a marble-tiled private space for the commode and bidet, and a blue-accented tray ceiling.

The twin bed-and-bath suites on the fifth-floor entitle the children to comparable pride and privacy. The gray and pea-green bedrooms have classic fireplaces and private baths bedecked in marble tile. Even the laundry room boasts a marble sorting counter.

The mansard roof forms a studio suite on the top floor, where a deluxe corner bar with wood paneling, granite and shellacked wood counters and mirror-backed glass shelves is ready for elegant entertaining.

A front bedroom suite with a marble fireplace and private shower bath is handy for putting up party guests. A wainscoted stair with turned balusters ascends to the two-level roof deck, where the historical grandeur of Back Bay and South End row houses combines with the contemporary colossus of the Hancock, Prudential and Downtown/Financial District towers to showcase Boston at its best.

Offered at $11 million, 89 Marlborough St. is a rare opportunity to enjoy skyscraper soar and rowhouse regality simultaneously.
