The residence collection

Six Seaport addresses.
Six distinctly different ways to live.

Six defining condominium addresses. Each offers a different relationship to the harbor, the neighborhood, and the way you want to live.

The residence map

Six residences.
See the neighborhood around each one.

Fan Pier is quiet and composed. Pier 4 reaches farther into the harbor. Echelon sits at the neighborhood’s active center. St. Regis occupies its own waterfront edge.

22 Liberty on Boston Harbor

01 · Fan Pier · 109 residences

22 Liberty

A quieter, more private way to live on the harbor.

Live asking range$895K–$6.475M
Homes available5
Median ask$2.449M

The most restrained of the Fan Pier addresses. It feels private, established, and unmistakably residential, with the water experienced through the home rather than through a resort-sized amenity program.

Why it works

  • Direct harbor position and Harborwalk access
  • Intimate scale with an established resale record
  • Quiet arrival, attentive staffing, strong privacy

What to weigh

  • Fewer amenities than Echelon or St. Regis
  • View, floor, and line create large price differences
  • Parking, balcony, and storage rights vary by home

50 Liberty on Fan Pier

50 Liberty

More space, more outdoor living, the same composed waterfront.

Live asking range$1.85M–$13.5M
Homes available4
Median ask$4.523M

50 Liberty keeps Fan Pier’s residential calm while offering a broader mix of larger plans, balconies, terraces, and entertaining space. It is often the better fit when 22 Liberty feels too restrained or compact.

Why it works

  • Direct waterfront with generous plans and glass
  • More balcony and terrace opportunities
  • Residential atmosphere without hotel operations

What to weigh

  • The penthouse makes the current price range look wider
  • Plan efficiency and outdoor space vary significantly
  • Harborwalk exposure and carrying costs need review

Pier 4

Water on three sides. The city behind you.

Live asking range$3.45M–$6.695M
Homes available4
Median ask$6.245M

Water on three sides, private balconies, and a smaller residential scale make Pier 4 the neighborhood’s strongest indoor-outdoor proposition. The best homes feel almost detached from the city behind them.

Why it works

  • Unusually close relationship to open water
  • Balcony-forward plans and intimate scale
  • Valet or self-parking and a private arrival

What to weigh

  • Current entry price is materially above the broader field
  • Wind, exposure, and balcony usability are residence-specific
  • View premiums jump when a line clears an obstruction

Echelon Seaport residences

04 · Central Seaport · 447 condominiums

Echelon Seaport

For the buyer who wants the building to be part of the life.

Live asking range$799K–$4.695M
Homes available25
Median ask$1.9M

Echelon is the social, amenity-rich counterpoint to Fan Pier. Its scale creates the Seaport’s widest choice of floor plans and price points, with daily dining, retail, fitness, and resident life immediately downstairs.

Why it works

  • The neighborhood’s deepest amenity program
  • Broadest range of layouts, prices, and inventory
  • Central position for dining, fitness, and daily errands

What to weigh

  • 447 condominiums create more resale competition
  • The experience is social and active, not discreet
  • Tower, line, parking, and amenity charges vary

St. Regis Residences Boston

05 · Commonwealth Pier · 114 residences

St. Regis

Here, service is not an amenity. It is the reason to live here.

Live asking range$1.499M–$44.5M
Homes available9
Median ask$3.599M

Service is not an accessory here; it is the product. St. Regis is the Seaport’s clearest lock-and-leave residence, built around a highly staffed arrival, wellness, entertaining, and the details that make ownership easier.

Why it works

  • High-touch service and true lock-and-leave ease
  • Strong wellness, guest, and entertaining amenities
  • Direct water position with newer interiors

What to weigh

  • Service comes with meaningful carrying costs
  • Sponsor inventory still competes with resales
  • The $44.5M Grand Penthouse distorts the range

One Harbor Shore

The rare chance to shape a Fan Pier home before it is finished.

Live asking range$1.195M–$3.519M
Homes available5
Median ask$1.645M

The final residential phase of Fan Pier brings new construction, customization, a serious wellness program, and a landscaped roof terrace to the waterfront. It is the fresh start in a pocket otherwise defined by established addresses.

Why it works

  • New construction and early-selection opportunity
  • Marina, park, Harborwalk, and Fan Pier setting
  • Contemporary wellness and rooftop amenities

What to weigh

  • No operating, resale, or association history yet
  • Delivery, completion, and final common costs require diligence
  • Sponsor inventory will shape near-term resale competition
