Life is good on the sunny side of Commonwealth Avenue and is about to get a lot better.

Unit 3 at 327 Commonwealth Ave. in the prestigious Back Bay is a completely renovated floor-through home, designed by Stanton Schwartz in 2018, where old and new intertwine seamlessly. This beauty, featured in Boston Modern Luxury Interiors, is listed by Judy Goldfarb of Coldwell Banker Residential Brokerage for $2,190,000.

Both period and contemporary amenities such as oversized windows with grand views of the Commonwealth Mall, original crown moldings and beautiful quarter-sawn oak flooring in a walnut stain impart style and grace.

State-of-the-art technology that includes WiFi-controlled forced air heating and cooling, Lutron lighting and a Sonos sound system imparts 21st century treasures.

“Practical” was not overlooked. To maximize storage, every closet, including a double one in the entry, has custom California Closet inserts. To simplify laundry day, the unit has a washer and dryer. For safety and convenience, a parking spot has direct access to the building’s rear door.

Still, the best part is the definitive “living space” that encompasses 1,345 square feet and includes two bedrooms and two bathrooms.

The L-shaped kitchen is another excellent example of the thoughtful planning and exquisite finishes that are throughout the entire unit. Overhead cabinets stretch to the ceiling and under-mount lighting keeps work surfaces free of shadows while simultaneously highlighting the quartz countertops and backsplash.

Chef-worthy appliances include a Miele induction top range, speed oven/microwave and dishwasher plus a Sub-Zero refrigerator with integrated panels. The huge center island seats three or more people.

The beauty-and-brains combination continues in the huge living room area, which is fully open to the kitchen. Triple crown molding with picture rail trim and detailed paneled wainscoting complement custom plantation shutters on windows in the wide bay area, adding panache to this elegant space. So do full-fluted columns on the wood-burning fireplace and the 13-foot-high ceiling that are “period” appropriate for this beautiful 1880 brownstone.

Classic and contemporary also live happily together in the dining room. Here, triple crown molding and a huge window with custom plantation shutters accent exuberant wallpaper by global lifestyle designer Kelly Wearstler. Contemporary pendant lights are a striking accent in this spacious room that seats eight-plus easily. Custom built-ins flanking the window work for decorative displays and/or sensible storage.

Luxury rules in the full guest bathroom in the bedroom corridor. The floating vanity with a Duravit one-piece sink/countertop and Toto commode complement the sleek step-in shower that has a floor-to-ceiling marble tile surround, a rain shower head and a two-shelf product niche.

A floor-to-ceiling stationary glass panel emphasizes the high ceiling and makes this large room feel even bigger while Brizo fixtures add sparkle. The floor boasts radiant heat.

A wide two-window bay area, a working fireplace with a marble surround and hearth plus French doors opening to a nicely-sized deck are glamorous features in the master suite. Double crown molding and detailed window casings are touches of period elegance that are right at home in this thoroughly modern room.

Ample storage space is a must today and the master suite does not disappoint. It begins in the king-bed size sleeping chamber with an extra-deep floor-to-ceiling built-in wardrobe customized with eight drawers and numerous cubbies and hanging spaces to keep clothing and accessories organized and readily accessible.

More specialized hanging areas, open shelving for shoes and additional cubbies are in the hallway leading to the en suite bathroom, essentially creating a custom walk-through California closet.

Another luxurious touch is the ultra-chic, intricately patterned Ann Sacks marble floor tiles (also with radiant heat) that start in the “walk-through closet” and continue into the sleek en suite bathroom. Waterworks fixtures complement white marble tile in the surround that stretches to the ceiling for the tub/shower ensemble and covers the vanity countertop. A “swinging” half door to the tub/shower is both practical and pretty.

Big and bright, the guest bedroom/office/nursery has a deep double closet. This multi-purpose space also has French doors that open to the deck.

An extra-deep, almost walk-in affair in the corridor offers more storage options. In addition to custom shelving/cubbies that stretch to the ceiling, this area has access to a crawl space. Extra storage is available in the common area of the basement as well.

On a side note, this brownstone was designed by architects (Charles K.) Kirby and (G. Wilton) Lewis and was built by James W. Tobey in 1880. The front façade was significantly remodeled between the late 1890s and early 1940s.

In 1907, former cotton manufacturer Herbert Dumaresq bought the property. He was a partner in Jordan, Marsh & Company – the operators of the famed Jordan Marsh department stores. Dumaresq lived at 327 Commonwealth Ave. for 20 years.

In 1954, the single family home was converted to nine apartments and in 1981 they were transformed into five condominium units.

There will be an open house from 1 to 3 p.m. on Saturday, May 4.
