## Property Overview

Mid-Century Modern Time Capsule With Awe Inspiring Views From Every Room

 Expansive views of the East River, United Nations, and both Manhattan and Brooklyn skylines welcome you to this very special duplex apartment in original condition from 1966. Master architects Harrison & Abramovitz, also the lead architects for The United Nations complex and Lincoln Center, designed 870 and 860 UN Plaza, which continue to be one of the most important modernist buildings in the country. This apartment, 31/32F, was purchased by the family when the building was built and has remained how it was originally conceived ever since. A true testament to great mid-century modern design.

 The rooms are all well-proportioned and spacious, especially the first floor public rooms which include a living room and dining room measuring in excess of 43" in combined length, and the 15" entry gallery with its glamorous curved staircase and ever so important wet bar for entertaining. The kitchen is large, with original finishes, and has a separate staircase to the upper level and an adjacent laundry room with sink. In addition to the 2 staircases, there is a private elevator connecting the two floors.

 Upstairs are 4 bedrooms including a very large primary suite with dressing room, and bathroom with double sinks and separate tub and shower. The other 3 bedrooms each have a private bathroom and there is tremendous closet and storage space both in the bedrooms and in the adjacent corridor. The upper floor also has an entrance to the building elevators and common hallway. There is central A/C and heat, and a private storage is included with the sale.

 870 UN Plaza is a top full service building boasting a full time staff of doormen, lobby attendants, concierge, resident manager, and offers valet dry cleaning. There is an amazing fitness center, Pilates studio, golf simulator, resident lounge with catering kitchen, and multiple sundecks with helicopter category views. The building has a private driveway and resident garage, and a bike room. Pets are permitted, with board approval, as is trust ownership.

 The monthly maintenance charge includes electricity and window washing. Showings by appointment.

Showing the 40 most recent of 43 recorded sales in this period.

Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below.

### How this price compares

- **Last sold price**: $2,900,000
- **Median sold price**: $2,500,000
- **Difference**: +$400,000 (+16%)
- **Comparable sales**: 3
- **Sales from**: October 2024 – May 2025
- **Middle half of those sales**: $2,048,750 – $2,537,500

Based on co-op four-bedroom sales in Beekman.

Square footage is recorded for only 2 of these 3 sales (67%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest.

This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Beekman instead.

### How these sales were negotiated

- **Sale-to-list price**: 89% (3 sales)
- **Sold below asking**: 100% (3 sales)
- **Typical time to find a buyer**: 152 days (3 sales)
- **Typical time to close**: 61 days (3 sales)

Based on co-op four-bedroom sales in Beekman with the required listing and closing data. Sample sizes vary by metric.

These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure.

Sales data through August 2026.

Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
