The glass curtain-wall design of shifting angular planes and the narrow triangular site formed by the Brookline Avenue/Boylston Street intersection not only give Pierce Boston a commanding sculptural presence in the Fenway, but also allow the units some of the broadest, deepest views of Boston.

“It’s not what you look at that matters, it’s what you see,” reads the Henry David Thoreau-attributed quotation in the lobby of Pierce Boston at 188 Brookline Ave. And there is plenty to see - and use and experience - at this lofty new residence, internally and peripherally.

To begin, Peruvian architect Bernardo Fort-Brescia of Miami-based Arquitectonica gave the 378-foot, 30-story condo/apartment tower an “appearance of slenderness which contributes to its sense of stature and presence,” he reported on Pierce Boston’s website.

“The materials palette is simply glass and metal that modernizes the building and allows legibility of the formal movement of the design and the site.”

The glass curtain-wall design of shifting angular planes and the narrow triangular site formed by the Brookline Avenue/Boylston Street intersection not only give Pierce Boston a commanding sculptural presence in the Fenway, but also allow the units some of the broadest, deepest views of Boston.

The soaring ceilings and windows augment the feeling of being “up there” and looking down on the city with pride of place while lending a light, airy feel to daily living.

The 2,451-square-foot, three-bedroom condo unit PH29D exemplifies these qualities by virtue of its 10-foot-6-inch ceilings, three exposures from floor-to-ceiling windows, and the penthouse level.

The L-shaped entry hall’s European oak floor leads to a choice of light-and-vista extravaganzas: the Great Room at left, or the bedroom suites at right. For starters, the hall’s left-hand leg passes a pocket door to a small but bright bedroom with two closets flanking a bed/couch alcove, which suits it for TV-room use.

To go beyond the screen to the sky, open the French door to a glass-railed balcony with a stunning view extending from the Emerald Necklace and Museum of Fine Arts to the Harbor Islands and Blue Hills.

The full bath across the hall establishes the theme of a white quartz vanity and marbleized quartz tiles contrasting dark walnut cabinetry in all three baths. Through a pocket door is a standup shower with a frosted-glass door that lets in light and preserves privacy simultaneously.

The great room’s floor-to-ceiling windows with tilt-out panes wrap around the corner, presenting a grand, deep, sweeping view of Boston. Dinner-party guests can feast their eyes on Fenway Park, the Citgo sign, the Charles River, Back Bay and Downtown office towers, the Emerald Necklace, the Harbor Islands, the Blue Hills and much more.

The real feast is easily prepped in the open kitchen that features a white quartz waterfall island counter/bar with deep sink, a white quartz wall counter with five-burner gas cooktop and stainless hood, dark walnut cabinetry with built-in refrigerator and ovens, and a dry bar with glass shelves, quartz counter and wine cooler.

When it gets cooler, a freestanding rectangular fireplace tiled in marbleized quartz is ready right across the space. French-door access to the balcony spills the entertainment out in the open.

The remaining two bedrooms have full en suite baths. Past a closet is a mid-sized bedroom with corner exposure from a glass-wall alcove.

The right-hand master suite begins at a walk-in closet with walnut cabinetry, more of which occupies a wall of the master bedroom, where a sumptuous southeastern sunrise view reaching from the harbor horizon to the Emerald Necklace greets you every morning. The master bath features a frosted glass-doored water closet to lighten up privacy.

One flight up, an expansive common roof deck with a pool, hot tub, teak decking and open-top window-walls, bridges the gap between indoor safety and outdoor sunshine. Soak in the cityscape from the lounge chairs by the pool, the shaded teak alcove with an upholstered running bench or at the galley lounge and outdoor kitchen - complete with grill, sink, fridge and furniture.

If the elements aren’t cooperating, inside is a vast common great room with couches, easy chairs, Ottomans, an open-flame gas fireplace, two TV screens, a marble dining table and a granite bar. A hall of blue glass wall/floor tiles that look cool and wavy when backlit accesses a chic dining room with saucer lights and woodgrain laminate paneling, followed by a dark oak-paneled library with a bookcase wall served by a ladder that moves on a track.

There’s more on the 18th floor. The Mezzo Lounge is a light-filled living room with sofa-bank and TV. The conference room boasts a TV screen and a wall sculpture of cushioned black paneling. The open city-view sitting area has upholstered booths and niche-seats.

The Great Room has a full caterer’s kitchen, a marbleized quartz island counter, sofas and easy chairs galore as well as an eyeful of designer lighting ranging from sculptural to tubular to webby and the breathtaking glass-wall exposure from the building’s acute-angled corner at the Brookline/Boylston crossroads.

The game room’s diversions include pinball, Pac-Man, Hoop Fever and miniature curling. A gym, pet spa and laundry are on Level 2.

The grand lobby’s fluorescent arches, saucer lights, abstract paintings and waterfall of stacked, rough, white marble present an artful introduction to the Fenway’s cultural offerings, which include the MFA, the Isabella Stewart Gardner Museum, the Red Sox at Fenway Park and movies at Regal Fenway Stadium 13 & RPX right across the street.

Offered at $4,872,300, Unit PH29D at Pierce Boston pierces the sky with a special blend of comfort, convenience and culture that lets you see and experience Boston in a new light.
