Construction has reached street level on 204 4th Avenue, a 13-story residential building in Gowanus, Brooklyn. With L+Z Architecture as the executive architect and developed by Avery Hall and Gindi Capital, the 200,000-square foot structure will yield 193 rental units and 14,000 square feet of ground-floor retail space, and is part of a wave of upcoming residential projects that is expected to dramatically transform the neighborhood following the approved Gowanus rezoning. Leeding Builders Group is the general contractor for the half-acre property, which is alternately addressed as 655 Union Street and bound by Sackett Street to the north and Raul Vasquez Jr. Place to the south.

Photos taken over the weekend show the ground floor taking shape with a dense array of concrete formwork, steel rebar, and scaffolding standing across the lot in preparation for the rise of the reinforced concrete superstructure’s walls and columns. YIMBY expects 204 4th Avenue to ascend steadily throughout the rest of the year, possibly topping out by the winter.

Most of the construction activity is occurring on the southern end of the plot, which was formerly occupied by a Speedway gas station.

The renderings from Avery Hall’s website depict a straightforward massing rising from a podium with multiple setbacks on the uppermost levels topped with landscaped terraces. The façade will be composed of dark gray paneling framing a grid of floor-to-ceiling windows. The first story features a double-height ceiling span for the residential lobby and retail space, and the main entrance is located on the southern elevation beneath a protruding canopy.

Residential amenities will include an outdoor rooftop swimming pool and lounge, coworking space, a children’s playroom, a fitness center, a pet-washing station, tenant storage, and a bike room.

204 4th Avenue has an anticipated completion date of January 2025, as posted on site.

  1. Excellent project.

    • Gowanus 101

      What’s Happening in Gowanus?
      The Canal

      The Gowanus Canal Was Designated a “Superfund Site”
      For over a century, the banks of the Gowanus Canal were line with industry and manufacturing companies, which released their toxic waste into the canal water as well into the ground. In 2010, the federal government identified the Gowanus Canal as one of the most toxic waterways in the entire country. It’s filled with toxins that pose serious public health risks. As a result, it was designated a “Superfund” site, and in 2020, the Environmental Protection Agency began a $1.5 billion cleanup of the canal.

      The Land

      The Gowanus Neighborhood Has Been Rezoned
      In 2021, 82 blocks in Gowanus were changed from mainly industrial use to allowing residential development. The existing industrial buildings being demolished in the neighborhood will soon be replaced by dozens of apartment towers reaching up to 30 stories tall.

      Most of the Rezoned Land is Highly Toxic
      The vast majority of development sites in Gowanus (see map, below) are filled with cancer-causing toxins due to a century of industrial use, and have been classified by NY State as “Brownfield sites.” Some have toxins as deep as 150 feet.

      The Infrastructure

      Sewage Frequently Flows Into the Canal
      During heavy rains, raw sewage flows into the canal because it exceeds the current sewer system’s capacity. As a result, the EPA has demanded that the City build two enormous “retention” tanks to keep excess sewage from going into the canal.

      What’s The Problem?
      The Land is Not Being Cleaned Up Fully, Leaving Toxins in the Soil
      All of these sites need to be cleaned up before residential buildings can be built. State law requires they be cleaned to “pre-disposal conditions”—as they were before industrial poisoning. However, this is NOT happening. For instance, at some sites, where toxins reach as deep as 150 feet, the State is only calling for developers to clean less than the top 8 feet of contaminated soil.

      Toxins Left in the Soil Can Enter Buildings And Threaten Future Residents’ Health
      The State itself acknowledges that when certain toxins (“volatile organic compounds” or VOCs) are left in the soil, they can “move into buildings and affect the indoor air quality.”

      Rather than remove them entirely, the State has decided that on the development sites, these toxins will be covered, or “capped,” with a slab of concrete. This method of dealing with toxic land, known as creating a “vapor intrusion barrier,” is very risky, and is so unreliable that these sites must be monitored every year, in perpetuity, to ensure that dangerous vapors haven’t penetrated people’s residences.

      The Most Deeply-Affordable Housing Is Planned for the Most Seriously Toxic Site
      Some of the worst contamination can be found at “Public Place,” a City-owned plot at the corner of Smith and Fifth Streets which for decades housed a manufactured gas plant that created waste known as “coal tar.” Exposure to coal tar has been linked to a variety of cancers. Coal tar at this site has been found to a depth of 150 feet.

      The cleanup proposed for this site is woefully inadequate, and only the top 8 feet of soil will be cleaned. It is also the only site in the entire rezone where 100% of the 950 apartments target lower incomes, including units for unhoused individuals and seniors. A school has also been proposed for this site.

      Placing the lowest-income residents in danger in this way raises Environmental Justice concerns.

      Toxins Are Not Confined To Their Original Sites and Threaten the Health of Existing and Future Residents
      Large “plumes” of migrating carcinogenic coal tar have already been found far from their original site in Gowanus, and with flooding and rising groundwater levels from climate change, these and other carcinogens can wind up underneath existing homes and intrude into them.

      Fumes from the Toxic Construction Sites Pose a Danger to the Community
      The disturbance of the land at these toxic construction sites has caused air monitors to be set off by toxic fumes reaching dangerously high levels, with the community not notified and only discovered after kids in the neighboring playground smelled it and reported it to our electeds.

      The Gowanus Canal will be Re-Contaminated With Toxins
      Without a full cleanup, toxins from the sites surrounding the canal will seep right back into the canal and re-contaminate it, thereby not only wasting $1.5 billion in taxpayer dollars, but also returning the canal to its dangerously toxic state.

      Sewage Retention Tanks Are Not Being Built, and Sewage will continue to flow into the canal—and into our homes
      The City is not following the EPA’s timeline to build the required retention tanks, and at this point says that they won’t be complete until after 2030. And the retention tanks are only meant to deal with the current number of residents in the community; they don’t take into account the additional sewage that will be produced by 20,000 planned future residents.

      Without the required retention tanks, and given increases in rainfall as a result of climate change, sewage will (and has) backed up into people’s homes.

  2. definitely nice looking building, and good neighborhood, I wonder will they have a good amount of truly AFFORDABLE HOUSING, that’s desperately needed in that area? or is this more for the market rate high middle income group as always
