- **Contract Purchase Price**: $1,150,000
- **Illustrative Buyer Commission Share**: -$17,250*

## Property Overview

Offering an exceptional blend of architectural scale, modern functionality, character, and space, this unique tri-level loft measures nearly 1,200 square feet and provides a versatile floor plan tailored to a variety of lifestyles. Architecturally designed as a large legal studio with 1.5 baths, the unit can function as a 2-bedroom or as a 1-bedroom plus an extra large 2-person home office.

The split-level living area features soaring high ceilings, hardwood floors, and custom built-in bookshelves that anchor the expansive room. Overlooking the living space, the primary sleeping loft functions as a private suite equipped with zen Japanese Shoji screens, a walk-in closet, and a full en-suite bathroom.

Down the stairs is an eat-in kitchen complete with generous counter space and stainless steel appliances, including a dishwasher and a vented range hood. A powder room is adjacent to the kitchen.

Descending to the lower level of the triplex reveals a spacious, highly adaptable bonus room with potential for a home office or secondary sleeping area enclosed by sliding Japanese screens.

Thoughtful storage solutions are integrated throughout the immense residence, including custom-built pull-out drawers beneath the staircase. Additional highlights include an in-unit washer and dryer, hardwood floors, and sound-proof double-paned windows with views of the Brooklyn Public Library across Grand Army Plaza.

Situated within a well-maintained, dog and cat-friendly Art Nouveau building that was originally built at the turn-of-the-century as the headquarters for the Long Island Automobile Club for early motoring enthusiasts, the building blends rich Park Slope history with modern boutique co-op living. Dedicated storage and bike storage are available, with Prospect Park, major subway lines (2, 3, B, Q), and a Citi Bike station all within immediate reach. Residents enjoy unmatched neighborhood amenities, most notably the renowned Saturday Grand Army Plaza Greenmarket right outside your doorstep.

Owners make no representation as to the legal use of the various levels as bedrooms. The building's offering plan designates Unit 1A a triplex with 4.5 rooms and 1.5 baths. Please consult your architect and/or attorney for information regarding regulations on use.

## Sales and market data

### Recent sales

3 apartments at 920 Union Street have recorded sales since October 2021, the most recent for $1,410,000 in September 2023. Prices are the figures recorded with the City, not asking prices.

| Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source |
| --- | --- | --- | --- | --- | --- | --- |
| 2-F (Duplex) | 1 | — | $1,410,000 | — | September 21, 2023 | MLS |
| 2-B (Apartment) | 1 | 900 | $814,000 | $904/ft² | November 5, 2021 | City record · MLS |
| 3B (Duplex) | 2 | 1,352 | $1,631,000 | $1,206/ft² | October 19, 2021 | City record · MLS |

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

- **This home**: $1,150,000
- **Median sold price**: $755,000
- **Difference**: +$395,000 (+52.3%)
- **This home, $/ft²**: $958
- **Comparable sales**: 38
- **Sales from**: November 2024 – August 2026
- **Middle half of those sales**: $617,500 – $842,625

Based on co-op one-bedroom sales in Park Slope.

Square footage is recorded for only 7 of these 38 sales (18%), 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 Park Slope instead.

### How these sales were negotiated

- **Sale-to-list price**: 100% (34 sales)
- **Sold below asking**: 41% (34 sales)
- **Typical time to find a buyer**: 39 days (38 sales)
- **Typical time to close**: 79 days (38 sales)

Based on co-op one-bedroom sales in Park Slope 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.

Based on recorded co-op one-bedroom sales in Park Slope. 2026 is year-to-date.

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.

This apartment is part of a co-op that is taxed as one lot shared across 17 apartments. The corporation’s 2026 property tax bill was $171,398 for the whole building. Shareholders cover it through their monthly maintenance rather than a separate bill for this unit.
