Project Goals

• Merge the two structures into a single workplace and knit their floor plates together.
• Install an elevator from grade to roof despite height limits and differing levels.
• Add a rooftop floor for gatherings while respecting landmark restrictions.
• Replace outdated building systems and provide reliable AV/IT across many conference rooms and 100 workstations.
• Supply ADA restrooms on every level and improve life-safety paths.
• Offer a warm, cohesive office that encourages staff to spend time on site after the pandemic.
  

Design and Implementation

Layout & Structural Changes

• New elevator tower—65 ft masonry shaft with brass-trimmed cab—lands at the main level; a short bridge connects the previously separated floors while a stair connects the 3rd floor mezzanine.
• Rooftop event floor framed in steel, set back for landmark approval, with exposed ductwork and lighting to heighten ceiling volume.
• Large floor openings cut and reinforced with steel beams to create internal sightlines and clear way-finding. Large windows repurposed as portals on either side of the bridge.
• Steel structure threaded through both buildings for the new floor and for local slab infills.
  

Mechanical, Electrical, and AV/IT

• All legacy window units, patchwork duct runs, and piping removed.
• New VRF with dedicated outside-air system, and sprinkler mains throughout.
• Distributed AV rack rooms serve video-ready conference spaces; low-voltage scheme coordinated with furniture vendor.
  

Materials and Finishes

• Cork flooring unites office areas; black-and-white marble marks lobbies and elevator fronts.
• Custom wood fire doors with antique-style brass hardware recall the era of the original buildings.
• Herringbone parquet and paneled millwork on the president’s floor conceal vents and diffusers.
  

Key Elements

• Landmark-approved elevator and rooftop level.
• Unified circulation spine that eliminates the former “maze” condition.
• Hybrid open/closed ceilings: exposed services in the event venue, concealed runs on executive floor.
  

Challenges

• Landmark District approvals for a new floor and exterior elevator tower.
• Off-set slabs demanded creative vertical circulation.
• Bedrock at elevator-pit depth slowed excavation.
• Strict budget control: value engineering removed extensive fire-rated glass yet preserved custom bronze and woodwork.
  

Outcome

The headquarters now blends restored detail with contemporary infrastructure. Staff and visitors move easily between departments, meetings start on time with dependable tech, and the event loft hosts town-halls as well as client briefings. Post-occupancy surveys show higher attendance than the firm’s previous offices, and leadership cites the project as a key part of their return-to-office success.
