Park Avenue Residence

4+ was hired to convert a doctor’s office in a landmark Park Avenue building into a duplex apartment. The original layout had steep exterior stairs leading to the entrance and a small spiral staircase to the lower floor, which was cramped and minimally functional.



4+ acquired an adjacent storage room, allowing for an efficient interior staircase and the addition of two bedrooms and bathrooms, greatly increasing the apartment's value.

Challenges and Solutions

Construction challenges included:

- Unexpected structural work

- Relocation of plumbing stacks

- Negotiation for space clearance with neighbors

- Installation of new plumbing, electrical, and HVAC systems

- Landmark permissions for facade changes and outdoor HVAC units

4+ took over management due to contractor issues, ensuring project completion.

Design and Features

The renovation retained the building's 1908 classic feel with:

- Classic mouldings, trim, and decorative finishes

- Custom hardware, doors, and cabinetry with walnut interiors

- Concealed lighting and air slots, maximizing ceiling height and storage

Key features include a full bar with a window to the kitchen and hidden bar counter. The design offers a light, tranquil space combining the luxury of a doorman building with the ease of townhouse living.
