Description

Welcome to 15 East 90th street, the landmarked Emily Trevor Mansion, a unique piece of Manhattan history.

This nearly 26 feet wide Park block Carnegie Hill Mansion boasts over 12,000 square feet, including two stunning terraces. The Mansion designed by Mott Schmidt underwent a complete renovation and modernization completed in 2022, with a special effort to preserve its original spirit, architecture and style.

All floors are accessible by the elevator, which has fully renewed equipment.

One enters into a grandly scaled traditional marble reception room, equipped with a wood-burning fireplace and stunning original ceiling murals based on the work of British architect Robert Adam, entirely restored by a specialty art conservation. A separate discreet service entrance allows direct passage to the spacious chef's kitchen.

The central kitchen has new Miele appliances, an oversized island, and direct access to the garden terrace. This area provides access to the lower level with not one but two gyms.

The enormous parlor floor comprises a grandly scaled south-facing living room flooded with light and a wood-burning fireplace. On the opposite side is a 26-foot butler's kitchen that services the dining room, perfect for hosting dinner parties.

On the third floor is the primary bedroom with its fireplace, spacious closets and stunning bathroom made in solid Quartz. Also situated on the third floor is the restored South facing library, made from substantial woodwork brought by boat in the XIX century. In this room, you can also find the fourth fireplace.

The upper staircase brings one to the fourth floor, where a media room separates two additional large bedrooms under a skylight.

Lastly, ascending to the sun-blasted 5th floor is a lounge, two additional bedrooms, a steam shower and a fully fitted sauna. The terrace on the 5th floor boasts 450 square feet and faces south, allowing the sun to shine throughout the day.

Lighting fixtures throughout the house are by Edward Caldwell

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
