Lantern House

Lantern House is a full-service condominium development designed by Heatherwick Studio and developed by Related, located along the High Line between 18th and 19th Streets. The building is known for its distinctive “lantern-shaped” bay windows, oversized layouts, strong natural light, and quiet residential feel despite being next to one of the most visited public spaces in Manhattan. It attracts buyers who want modern construction, high-end finishes, private views, and immediate access to Chelsea’s waterfront and gallery district.

Architecture and Design

Lantern House’s defining feature is its curved bay windows. They project outward in a lantern-like form, giving each residence a wide-angle view and more usable interior space along the windows. These are not decorative shapes; the curve physically enlarges the window area, expands sightlines, and brings in more natural light from multiple directions. Taller ceilings combined with these windows make the living spaces feel more open than traditional flat-windowed condos.

The building is split into two towers on either side of West 18th Street, connected visually by the High Line running directly past the façade. The exterior uses brickwork that references the industrial history of Chelsea, while the window design introduces a contemporary element. Inside, finishes include wide-plank European oak floors, marble kitchens, custom cabinetry, and high-end appliance packages (Gaggenau, Miele, etc.).

The amenity bridge that spans 18th Street is glass-walled, giving residents views of the High Line as they walk through it. This is a signature design feature unique to Lantern House.

Layouts and Livability

Residences range from large one-bedrooms to expansive four-bedroom penthouses. Lantern House is known for layouts that feel more substantial than what’s typically found in new Manhattan construction.

Key layout advantages:

• • • • • Oversized living rooms thanks to the extended bay-window shape
          
          

        • Dining areas in most two-bedrooms and larger
          
          

        • Kitchens with full-height storage and generous counter space
          
          

        • Primary suites with large walk-in closets and five-fixture bathrooms
          
          

        • Secondary bedrooms sized for real use (not the “office-bedroom” you see in many new builds)
          
          

        • Multiple exposures in corner units for stronger light and better privacy
          
          

        • Deep window seats created by the lantern windows, which buyers actually use for seating or shelving
          
          

The building reads as quiet and residential inside. Even with the High Line outside, the glazing system is thick enough to keep the interior peaceful. Higher floors get Hudson River views; mid-level units overlooking the High Line get greenery and open sky while avoiding the noise profile of street-level traffic.

Buyers who want actual space — not just glossy finishes — tend to connect strongly with Lantern House’s floorplans.

Amenities

Lantern House has a full-service amenity package, sized to match the building and clearly designed for daily use rather than show.

• • • • • 24-Hour Concierge and Doorman: Fully staffed entrances and lobby areas.
          
          

        • Pool: Large, hotel-style lap pool with natural light.
          
          

        • Fitness Center: High-end gym with cardio machines, free weights, strength equipment, and separate studio space.
          
          

        • Spa Facilities: Sauna and steam rooms.
          
          

        • Residents’ Lounge: Seating, tables, and Wi-Fi for work or informal gatherings.
          
          

        • Coworking Areas: Dedicated tables and semi-private workrooms.
          
          

        • Children’s Playroom: Well-lit space with activity zones.

        • Parking: On-site garage access.
          
          

The amenity bridge between the two towers is one of the most unique components and gives residents an elevated common area above the street.

Location

Lantern House sits in the center of West Chelsea, one of the most desirable locations for buyers who want access to:

• • • • • The High Line literally next to the building
          
          

        • Chelsea Piers and Hudson River Park for running, biking, and waterfront activities
          
          

        • Art galleries concentrated between 10th and 11th Avenues
          
          

        • Meatpacking District, about five minutes south
          
          

        • Chelsea Market and retail along 10th Avenue
          
          

        • Restaurants, cafés, and boutique shops throughout the surrounding blocks
          
          

Transit is a short walk to the A/C/E or the 7 train at Hudson Yards. Buyers often choose this area because they prefer the waterfront lifestyle and don’t mind a 5–10 minute walk to subways.

Despite the foot traffic on the High Line, the residential side of the building is quieter because it faces the water and interior streets rather than 10th Avenue.

Market Performance and Buyer Profile

Lantern House attracts a mix of:

• • • • • End-users looking for large, modern layouts and strong amenities
          
          

        • Buyers upgrading from smaller downtown condos
          
          

        • Pied-à-terre buyers who want a visually striking building
          
          

        • High-net-worth buyers who want luxury new construction near the water
          
          

Resale performance is strongest for:

• • • • • corner units with multiple exposures
          
          

        • larger two- and three-bedrooms with river views
          
          

        • High Line–facing units above tree level
          
          

        • penthouses with terrace space
          
          

The combination of size, design, and amenities makes Lantern House competitive with other high-end new developments in Chelsea and Hudson Yards.

Strengths

        • Strong amenity package with pool, spa, and coworking
          
          

        • High Line frontage with quiet interiors
          
          

        • High-quality finishes and appliances
          
          

        • Prestigious Chelsea waterfront location
          
          

        • Full-service building with strong long-term appeal

Considerations

• • • • • Distance to subway requires a short walk
          
          

        • High Line visibility (buyers should evaluate privacy on lower floors)
          
          

        • Some lines have more limited river views than marketing suggests
          
          

        • Monthlies reflect the full amenity package and luxury-level staffing
