## Property Overview

Tastefully designed by Resolution: 4 Architecture, this gallery-like corner residence brings downtown contemporary sensibility to a classic Emory Roth building.

 Oversized windows wrap West End Avenue and tree-lined 75th Street, offering exposures from multiple directions and consistent natural light throughout the day.
 Originally configured as ten rooms and thoughtfully combined into seven, the apartment now lives as a four-bedroom, three-and-a-half-bath layout centered around a grand 28' living and dining room. The scale supports both entertaining and daily living with ease.The fully windowed kitchen is modern and refined, featuring custom white lacquer cabinetry, top-tier Miele appliances, and generous counter space. A den separated by a sliding pocket door provides flexibility for media, office, or guest use. Integrated AV and surround sound are built into the home. The corner primary suite includes a spa-style bath and custom, generous dual walk-in closets. Three additional bedrooms are well proportioned and supported by two full baths. A proper powder room, dedicated laundry room, central air conditioning, hardwood floors throughout, substantial storage, and exposed beams complete the interior.

 Built in 1927 by Emory Roth, 310 West End Avenue is a full-service cooperative with a 24-hour doorman, live-in superintendent, private storage, bike room, and laundry facilities. Pet-friendly and located one block from Riverside Park, with convenient access to playgrounds, bike paths, dog runs, express transportation, neighborhood markets including Fairway and Citarella, and the Upper West Side's dining and retail corridors.

 Assessment: $1,239/month through 2030.

- **Last sold price**: $5,400,000
- **Median sold price**: $2,787,500
- **Difference**: +$2,612,500 (+93.7%)

Based on co-op four-bedroom sales in Upper West Side.

Square footage is recorded for only 19 of these 48 sales (40%), 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 Upper West Side instead.

### How these sales were negotiated

- **Sale-to-list price**: 95.5% (42 sales)
- **Sold below asking**: 74% (42 sales)
- **Typical time to find a buyer**: 89 days (43 sales)
- **Typical time to close**: 98 days (43 sales)

Based on co-op four-bedroom sales in Upper West Side 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.
