Rocklyn Asset’s 139 Van Siclen Avenue Project Files Permits for 157 Unit Brooklyn Build

• Rocklyn Asset Corp, led by Robert Dadona, filed permits for a 157-unit residential project
• The development spans 170,535 square feet across 14 stories in Cypress Hills
• Site sits near transit, supporting long-term rental and condo demand

What the permit filing means for Brooklyn development

A new mid-rise residential project is moving forward in Cypress Hills as Rocklyn Asset Corp files permits for 139 Van Siclen Avenue. The proposed 14-story building marks another step in the steady expansion of housing across emerging Brooklyn neighborhoods. The project is still in early stages, with demolition permits not yet filed. However, the application signals a clear intent to bring new density to a transit-connected corridor.

What the unit mix and size mean for positioning

Plans call for 157 residential units across 170,535 square feet, with an average unit size of 1,086 square feet. That layout suggests a likely condominium strategy, with units sized larger than the typical rental product in the area. The building will rise 145 feet and include a cellar level along with limited on-site parking. The scale positions the project as one of the more significant residential additions in Cypress Hills.

What the developer strategy shows

Rocklyn Asset Corp, through Robert Dadona, is targeting a neighborhood that continues to see gradual investment but still offers lower entry costs compared to core Brooklyn markets. By assembling a larger-scale project near transit, the developer is aligning with a proven strategy. Build near subway access, deliver larger units, and capture demand from buyers priced out of more established areas.

What the location means for demand

The site sits between Atlantic Avenue and Fulton Street, just steps from the Van Siclen Avenue subway station served by the J and Z lines. This connectivity supports both rental and condo demand, especially for commuters heading into Manhattan. As infrastructure remains a key driver of value, projects like this benefit from built-in accessibility without requiring major neighborhood repositioning.

What to watch as the project moves forward

The next step will be demolition filings, followed by construction timelines and potential financing details. No completion date has been announced yet. Architect Guido Hartray of Marvel is leading the design, which will shape how the project competes within the local market. For investors and landlords, this filing highlights continued development momentum in outer Brooklyn. As pricing pressures push demand outward, neighborhoods like Cypress Hills are seeing increased attention from developers seeking scale opportunities.
