One Wall Street – the largest office-to-condo conversion in the history of New York – is moving towards major milestones in the construction process, including the 16-month painstaking restoration of the iconic Red Room.

A prized Ralph Walker art deco creation, the Red Room was designed in 1931 by renowned muralist Hildreth Meière, who covered its walls and ceiling in 8,911 square feet oxblood, orange and gold glass tile mosaic.

This $1 million dollar restoration project includes the delicate mending of damaged tile, grouting and shining. The Red Room served as the building’s banking hall and is considered one of New York City’s most iconic spaces. Following the restoration, the Red Room will likely become an opulent new retail space with its doors expected to open in 2021.
