820 Classon Avenue is an eight-condo building on Classon Avenue between St. Johns Place and Lincoln Place in Crown Heights, a few minutes from Prospect Park and the Brooklyn Museum. An existing four-story residential building was enlarged and rebuilt, and with the penthouse going into contract on October 26, every home is now sold or in contract, about six months after sales launched.
Where Things Stand
As of November 1, 2026, seven of the eight homes at 820 Classon Avenue have closed and the penthouse is in contract. The Attorney General accepted the offering plan on April 10, 2026. The first homes listed on April 21, 2026, and the last contract was signed on October 26, 2026, about six months later. The only other Brooklyn project of 7 to 29 homes I've tracked to a sellout, 755 Washington Avenue, also took about six months, so this one moved at a similar pace. The developer is Investmates Real Estate Development. Want to see upcoming projects by this sponsor? Reach out below.

Buying in a New Development?
New construction works differently than a resale: offering plans, sponsor contracts, closing costs and timelines all have their own rules.
A Closer Look at the Building
The building mixes small and large homes: a duplex studio and three one-bedrooms on the lower floors, three two-bedrooms with balconies above, and a penthouse duplex with a private roof terrace and keyed elevator entry. Every home has an in-unit washer and dryer and central heating and cooling. The one to note for outdoor space below the penthouse is 1R, a duplex with its own backyard and a finished basement.
Crown Heights Highlights
This stretch of Classon Avenue is about as close to Prospect Park as Crown Heights gets, with the Brooklyn Museum, the Brooklyn Botanic Garden and Grand Army Plaza all a short walk away, and the cafes and restaurants of Franklin and Washington Avenues a few blocks in either direction.
The 2 and 3 at Eastern Parkway-Brooklyn Museum, about a 4-minute walk
The 2, 3, 4 and 5 at Franklin Avenue and the shuttle at Botanic Garden, about 6 minutes on foot
Prospect Park, the Brooklyn Botanic Garden and the Brooklyn Museum, all within a few minutes
Katie's Take
I track every new development in Brooklyn, and here's how this one compares: 820 Classon Avenue sold below 701 Prospect Place and close to 582 Park Place on price per square foot, which is a fair price for a location this close to Prospect Park. Most of the smaller homes went into contract within a few weeks, while the penthouse took a price cut and a relaunch before it found a buyer, a pattern I keep seeing in Crown Heights: demand is strongest under about $2 million. If you're looking near the park in that range, 598 Sterling Place and 811 Classon Avenue are still selling nearby.
