Architecture and Design

The project blends a restored prewar façade with a modern extension that cannot be seen from the street, preserving the block’s character while allowing for contemporary layouts.

Key architectural points:

• Original façade reworked under landmark guidelines
  
  
• New rear volume allows for larger and more efficient interiors
  
  
• Wider window spans than typical prewars
  
  
• Quiet, low-density block that enhances residential feel
  
  

Interiors typically feature:

• Wide-plank hardwood floors
  
  
• Custom European-style kitchens with integrated appliances
  
  
• Stone counters and full-height backsplashes
  
  
• Clean-lined, stone-clad bathrooms
  
  
• HVAC systems and updated mechanicals
  
  
• Generous closet space for a boutique building
  
  

The design approach aims for long-term usability rather than trend-based fixtures.

Layouts and Livability

Layouts are one of the building’s strongest qualities. Because of the combination of the restored structure and new addition, units are larger and more functional than many prewar conversions.

Common layout advantages:

• Large living rooms suitable for real furniture and dining tables
  
  
• Bedrooms that actually fit long-term furniture sizes
  
  
• Primary suites with modern bathrooms and storage
  
  
• Multiple exposures in some units
  
  
• Private terraces or balconies in select residences
  
  
• Washer/dryer in each home
  
  
• Duplex layouts available in some units, offering separation of space
  
  

Even though the building sits in a busy part of the Upper West Side, it remains quiet and residential due to the block’s low traffic and rowhouse proportions.

Buyers who want prewar context but modern interiors find this combination ideal.

Amenities

Amenities are intentionally limited to keep monthly charges reasonable.

• Virtual Doorman
  
  
• Elevator
  
  
• Private outdoor space for select units
  
  
• Storage units
  
  
• Package area
  
  
• Bicycle storage
  
  

No doorman or full-service amenity footprint, which appeals to buyers wanting modern convenience without high carrying costs.

Location

This is one of the most consistently desirable pockets of the Upper West Side.

Nearby advantages:

• American Museum of Natural History half a block away
  
  
• Central Park (short walk)
  
  
• West 81st Street retail corridor
  
  
• Columbus Avenue restaurants and cafes
  
  
• B and C trains at 81st Street
  
  
• 1 train at West 79th Street
  
  
• Close to Zabar's, Barney Greengrass, and neighborhood markets
  
  

The block is low-traffic and residential, offering a calmer feel than nearby avenues.

Considerations

• Limited inventory due to boutique size
  
  
• Some units in the original structure may have differing ceiling heights or window proportions

Coverage centered on:
