At Penthouse 5A, the smell of chocolate candy no longer permeates the air, but living here is sweet with amazing views from every window. David Green of Coldwell Banker Realty is offering the unit for $1,649,000.

For a hundred years, local children got their education in a parochial schoolhouse atop the highest point in Charlestown. According to the parish website, the mission of the Dominican Sisters of Kentucky was to “teach the children of the pioneers.”

Imagine, the windows having stencils of wintry characters greeting the kids as they made their way up the steep and slippery slope every morning or the sweet smells from the nearby Schraftt’s Candy Company wafting through the open windows in the springtime enticing the students.

The journey from schoolhouse to penthouse began in 1996 when St. Francis de Sales Parochial School was sold and Orchard Hill Condominium Association was founded. The building was refurbished and the top floor auditorium that once held assemblies and an annual St. Patrick’s Day play was turned into luxury homes.

“It’s so quiet and private,” he says, “It’s a dream.”

The home retains vintage charm and integrates it handsomely with a chic modern design.

On the lower level of this townhome are the private spaces.

The primary bedroom is tastefully accented and comfortably crafted. Two Palladian windows in the primary bedroom suite frame views of Doherty Park and the steeple of the St. Frances de Sales church across the street. Every morning, you can watch tugboats chugging along the Mystic River while gazing across to Assembly Row, the Encore casino and the tall white wind turbine.

Sunshine sparkles on the gleaming hardwood flooring. To the far end of the room is a gas fireplace with two built-in bookcases. There is ample room to set up a seating area in front of the hearth and a king-sized bed on the opposite wall. Other furniture, such as dressers and nightstands, co-mingle nicely. Sconces and globes adorn the walls and ceilings, adding ambient lighting in just the right places. The custom walk-in closet can accommodate a sizeable wardrobe.

The spa-like en suite bathroom was created using principles of Universal Design so people of diverse abilities can enjoy this shining space. The gleaming white-tiled walk-in shower is enclosed by glass doors and has the luxury of multiple shower heads. The long vanity holds a pot-belly sink. The floor is covered with warmly colored marble which complements the color of the countertop.

The spacious guest bedroom rocks another Palladian window, sharing the splendid view. There’s ample room here for a dresser opposite the bed and a desk fits nicely into a corner near the window. The walk-in closet welcomes guests to hang up their clothes and stay awhile.

The guest bedroom has its own stunning bathroom with a glass enclosed soaking tub, a shimmering wall of sea green glass tile and a nicely-sized vanity with a rectangular sink.

A laundry room is situated between the two bedrooms. A full-sized LG washer and dryer serves the home.

The living level upstairs boasts a voluminous open floor plan - perfect for entertaining. The gourmet cook’s kitchen beckons. It was renovated recently and the polished Super White Calacatta marble counters look gorgeous atop modern white cabinets. Storage is plentiful.

Top-of-the-line appliances include a huge Sub-Zero refrigerator, a Miele oven and dishwasher, and an induction cooktop that will appeal to serious home chefs who appreciate its fast heating and temperature control. You’ll want to drink your morning coffee seated at the island, basking in the light streaming through multiple windows.

The kitchen rolls out into a lovely “great room” with nooks and crannies for living and dining furniture. There’s even a space for a piano, suggesting a sing-along with family and friends.

One of the focal points in this room is the second gas fireplace. Another is the glass shelves that will be even more elegant once the new owner’s display their colorful collectibles.

A powder room sits nearby.

What is truly memorable about this home is that it gives you a chance to observe some of the most breathtaking views in Boston. Through the many oversized windows on this level, the city is displayed in every direction. Landmarks such as the Back Bay skyscrapers, the Charlestown Monument, the Zakim Bridge and the control tower at Logan Airport stand out.

On either side of the hearth are French doors that open to the private balcony that reveal more magnificent vistas. From here, the view extends from Harvard University’s Memorial Hall to the North End’s Old North Church. The panorama encompasses a sliver of water view with sun dancing on the waves. City lights twinkle like jewels in the evening. Vibrant colors of the gorgeous sunrises and sunsets are painted across the horizon. It’s the perfect place to host a July 4th party and enjoy the fireworks from several surrounding communities.

Back inside, the dramatic vaulted ceiling introduces the stairs that lead to the cozy loft area - ideal for an office or den. Built-ins organize the space and a skylight illuminates it. You might even choose to use it for an occasional guest. It’s all in how you decide to furnish it.

Orchard Hill only has 26 units, giving it a boutique feel. The beautiful brick building has common spaces that include an exercise room, a landscaped patio and an underground garage. Penthouse 5A comes with two deeded parking spaces.
