If you are shopping for a luxury condo in Seaport, one question matters more than almost anything else: which building actually fits how you want to live? In 02210, several full-service buildings can look similar at a glance, but the day-to-day experience can feel very different once you compare views, amenities, service style, and monthly costs. This guide will help you sort through the main full-service luxury condo options in Seaport so you can focus on the building that best matches your priorities. Let’s dive in.
What full-service means in Seaport
In Seaport, full-service usually means a building with 24/7 concierge or doorman coverage, garage parking, and a stronger amenity package than a standard condo property. Depending on the building, that may also include clubrooms, pools, spas, fitness space, valet, sports simulators, or pet services.
That shared label can be misleading, though. Some Seaport buildings feel more like hotel-style towers with a large amenity campus, while others feel more residential and waterfront-focused. If you are deciding between buildings, it helps to compare not just finishes and price, but also the kind of daily lifestyle each one supports.
Seaport’s main luxury condo buildings
The core owner-occupied luxury shortlist in Seaport usually includes 22 Liberty, 50 Liberty, EchelonSeaport, Pier 4, and the Residences at the St. Regis. One Harbor Shore is also important to watch, but it is best viewed as a future buying opportunity rather than a current resale comparable because delivery is scheduled for late 2026.
Most of these headline buildings cluster around Fan Pier and the Seaport Boulevard corridor. Fan Pier is centered around Harborwalk, a marina, public space, retail, and restaurants, which is part of why waterfront buyers often focus so closely on this part of the neighborhood.
22 Liberty
Why buyers consider 22 Liberty
22 Liberty is the first luxury condo building at Fan Pier and remains one of the clearest choices for buyers who want a classic direct-waterfront Seaport address. It is a 14-story building with 109 residences, and its glass design was planned to open up harbor views while also preserving privacy.
For many buyers, 22 Liberty stands out because it feels a bit smaller in scale than the largest amenity-heavy towers. If your priority is harbor orientation, a polished full-service experience, and a quieter residential feel, this building often lands on the shortlist quickly.
Unit style and amenities
Current listings commonly show dark oak floors, floor-to-ceiling glass, marble baths, and high-end kitchens with Sub-Zero, Wolf, and Miele appliances. Some homes also feature 10- to 14-foot ceilings and private terraces or balconies.
Building services and amenities typically include 24/7 concierge, a doorman, garage parking, a club room with terrace, and a gym. It is a strong fit if you want full service without paying for an oversized resort-style amenity package you may not use often.
Typical condo fee range
Current listing examples show monthly condo fees ranging from about $940 to $4,245. Many standard residences appear to fall roughly in the $1,500 to $3,600 range.
50 Liberty
Why buyers consider 50 Liberty
50 Liberty is the sister building to 22 Liberty and is another top-tier Fan Pier waterfront option. It is also 14 stories, but with 120 residences and a design that emphasizes water and sky through large window walls.
Buyers often compare 50 Liberty directly with 22 Liberty because both offer direct harborfront living. In practical terms, 50 Liberty may appeal to you if you want that same Fan Pier location with a slightly newer and slightly more expansive feel.
Unit style and amenities
Current listings often show open layouts, waterfront terraces or balconies, high-gloss white lacquer cabinetry, waterfall islands, and Sub-Zero, Wolf, and Miele appliances. The homes tend to read as sleek and contemporary, with a strong visual connection to the water.
Amenities and services commonly include 24/7 concierge or doorman coverage, a fitness center, resident lounge or club room, a boardroom, and garage parking. For many buyers, the appeal is straightforward: direct waterfront living with a polished, modern full-service setup.
Typical condo fee range
Current examples run from about $909 to $7,717 per month. Many standard homes appear to be around roughly $1,900 to $3,640.
EchelonSeaport
Why buyers consider EchelonSeaport
If you want the deepest amenity stack in Seaport, EchelonSeaport is often the first building buyers examine. The condominium towers at 133 and 135 Seaport Boulevard are designed with stepped stone-and-glass forms, and the broader project promotes more than 50,000 square feet of amenities.
Echelon feels more like an amenity-rich Seaport Boulevard campus than a quiet harborfront enclave. That makes it especially appealing if your ideal building includes a more active social and fitness lifestyle built into daily life.
Unit style and amenities
Current listings often feature floor-to-ceiling windows, white oak floors, Caesarstone quartz counters, electric shades, and dedicated work areas. Many homes also include parking or storage packages.
The amenity lineup is a major part of the story here. Public information points to three pools, an indoor pool, an 8,500-square-foot wellness center, yoga and fitness space, a basketball court, lounges, and Regent-branded service standards.
Typical condo fee range
Current examples run from about $921 to $4,675 per month. Many homes appear to be in the low-thousands.
Pier 4
Why buyers consider Pier 4
Pier 4 fills an important niche in Seaport because it offers a more boutique-scale waterfront experience. The building includes 106 homes, and many buyers are drawn to the combination of strong water exposure, modern design, and a smaller overall residential feel.
If the largest towers feel a bit too busy for your taste, Pier 4 can be a compelling alternative. It still delivers a full-service experience, but with a scale that may feel more intimate.
Unit style and amenities
Public listings emphasize corner exposure, broad water and skyline views, and private garage parking. The homes read more like modern waterfront residences than a super-tall tower product.
Amenities include concierge and management, a Topsider lounge with catering kitchen, a fitness and wellness center, a golf simulator, a dog spa, and a seaside sky terrace with grill and fire pit. That mix gives Pier 4 a distinct identity, especially for buyers who value indoor-outdoor resident spaces and pet-friendly features.
Typical condo fee range
Current examples run from about $1,658 to $7,686 per month. Many homes appear to fall in the mid-$2,000s to low-$3,000s.
The Residences at the St. Regis, Boston
Why buyers consider St. Regis
For buyers seeking the most hotel-like service package in Seaport, St. Regis Residences usually stands in a category of its own. The waterfront tower opened in November 2022 and includes 114 residences in a 22-story building.
This is often the building buyers tour when branded service, valet, and a more elevated hospitality feel matter most. It is a strong match if you want luxury living that feels closest to a private residence paired with high-touch hotel-style operations.
Unit style and amenities
Official residence descriptions highlight floor-to-ceiling windows, walk-out or Juliet balconies, wide-plank oak floors, custom Italian cabinetry, Wolf and Sub-Zero appliances with wine storage, polished marble counters, spa-inspired baths, and heated primary bath floors.
The amenity package includes a Grand Lounge overlooking the harbor, a bar and wine vaults, a sports simulator, an indoor pool with Jacuzzi, steam room and sauna, and a 12,000-square-foot amenity level with an outdoor terrace. Current listings also reference 24-hour concierge, valet parking, and a door attendant.
Typical condo fee range
Current examples range from about $1,742 to $22,930 per month. Most standard residences appear to sit in the low-to-mid $2,000s, with much larger homes rising sharply from there.
One Harbor Shore
Why it matters now
One Harbor Shore is the final Fan Pier waterfront phase and one of the most important future opportunities in Seaport luxury. It is still pre-selling and is scheduled for late 2026 delivery, with 122 residences planned.
For now, the right way to think about One Harbor Shore is as a next-generation direct-waterfront purchase option, not as a current resale building. If you are open to waiting for delivery, it may deserve a place in your search.
Planned features
Marketing highlights abundant glass, custom Italian cabinetry, Wolf and Sub-Zero appliances, concierge service, a roof terrace, a Grand Lounge overlooking the marina and harbor, and a Recovery Room with sauna, cold plunge, and Vitamin C shower.
The building is also being marketed around marina access, boat docking, water taxi service, and ferry access. That waterfront integration gives it a distinct angle compared with currently completed buildings.
How monthly costs compare
One of the biggest surprises for buyers is that the building name alone does not explain monthly HOA costs. Across current examples, St. Regis shows the highest HOA ceiling, while 22 Liberty, 50 Liberty, EchelonSeaport, and Pier 4 often cluster in the low-thousands for standard residences.
The spread is often driven more by unit size, floor height, view corridor, outdoor space, and service load than by the building itself. In other words, two homes in the same building can have meaningfully different carrying costs if one has larger square footage, stronger views, or a more premium position.
Which building fits your lifestyle
Choose Fan Pier for classic waterfront living
If your priority is direct harbor orientation and a more established waterfront feel, 22 Liberty and 50 Liberty are often the strongest pure Fan Pier plays. These buildings are closely tied to Harborwalk, marina access, nearby dining, and the broader Fan Pier setting.
Between the two, 22 Liberty may feel a touch more intimate, while 50 Liberty may feel slightly more expansive and contemporary. For many buyers, the decision comes down to unit-specific views, layout, and monthly carrying costs.
Choose Echelon for amenities
If you care most about pools, wellness space, fitness options, and a more social resident environment, EchelonSeaport is usually the standout. It offers the broadest amenity package among the established Seaport condo choices.
That makes it a practical fit for buyers who want the building itself to function as part of their daily routine, rather than simply a place to come home to.
Choose Pier 4 for boutique scale
If you want to stay on the waterfront but prefer a smaller-building atmosphere, Pier 4 deserves close attention. Its amenity package is still strong, but the overall scale can feel more personal than some of the larger towers.
It is especially appealing if you value features like a dog spa, golf simulator, and resident lounge spaces with a strong indoor-outdoor connection.
Choose St. Regis for hotel-style service
If branded service, valet, and a high-touch hospitality feel are at the top of your list, St. Regis is the clear reference point. It is the most hotel-style option among the current Seaport buildings.
This can be a great match if service standards and a refined amenity experience matter just as much to you as the residence itself.
Choose One Harbor Shore if waiting works
If you want new direct-waterfront inventory and are comfortable with a future delivery timeline, One Harbor Shore is the building to watch. It offers a rare chance to buy into the final Fan Pier waterfront phase.
For some buyers, waiting is worth it to access a brand-new product with marina-centered features and a fresh amenity concept.
What to know about location and access
Seaport’s waterfront buildings are not interchangeable from a location standpoint. 22 Liberty and 50 Liberty are strong Fan Pier waterfront addresses, Pier 4 sits at the water’s edge with immediate Harborwalk and ICA access, St. Regis has its own pier and Harborwalk connection, and Echelon is a bit more inland along Seaport Boulevard.
That difference affects how the neighborhood feels on a daily basis. Some buyers want to step directly into a harborfront setting, while others are happy to trade a little waterfront immediacy for a larger amenity ecosystem.
In terms of transportation, the safest way to think about this pocket of Seaport is walkability to Silver Line service paired with garage or valet parking, rather than direct subway access. For many buyers here, the real comparison is walkability plus parking convenience, not heavy-rail proximity.
How to narrow your short list
Before you tour, it helps to rank your priorities in order. In Seaport, the best building for you is usually the one that lines up with your lifestyle first and your wish list second.
A practical way to narrow the field is to ask yourself:
- Do you want direct waterfront views or the largest amenity package?
- Do you prefer a boutique building or a larger tower?
- How important are valet, pools, spa features, or pet amenities?
- Are you comfortable with higher HOA costs for more service?
- Do you want a move-in-ready resale now, or are you open to waiting for new construction delivery?
When you answer those questions clearly, the shortlist usually becomes much more manageable.
If you are weighing Seaport buildings, building-specific guidance matters. Small differences in orientation, layout, carrying cost, and service style can have a big effect on both lifestyle and long-term value.
