Development 

Diamond Dev Group is a New York–based real estate development company with over $100 million in assets under management.

Our vertically integrated team manages the entire lifecycle of a project — from acquisition and design through construction, leasing, and final sale.

Our partners hold professional licenses across all critical disciplines, including architecture, structural and mechanical engineering, real estate brokerage, leasing, construction, and property management. This in-house expertise allows us to control quality, timelines, and costs at every stage of development.

Through long-standing relationships with vendors, lumber yards, and suppliers, we source materials directly from manufacturers, securing competitive pricing and reliable access to high-quality products such as tile, mosaics, stone slabs, wood flooring, interior finishes, and appliances.

Diamond Dev Group specializes in high-capitalization projects with strong upside potential, executing strategies ranging from fix-and-flip to long-term buy-and-hold investments across all New York City boroughs.

The firm remained cash-flow positive throughout the COVID-19 pandemic, demonstrating disciplined risk management and a proven track record of securing and protecting investor capital.
