The Original Brownstone Group, often abbreviated as OBG, is a renowned real estate development and investment firm based in New York City. Established in the late 1980s, the company has carved a niche for itself in the competitive NYC real estate market, leaving an indelible mark on the city's architectural landscape. OBG is not just a group of real estate professionals; it is a collective of visionaries who strive to redefine urban living spaces through innovative design and sustainable practices.

OBG's portfolio spans across various neighborhoods in NYC, including Brooklyn, Manhattan, and Queens. The group is known for its transformative projects that breathe new life into old, often neglected, buildings. By preserving the historical charm of these structures while incorporating modern amenities and eco-friendly features, OBG has successfully created unique, sought-after living spaces that cater to a diverse range of residents.

The Founders and Their Vision
The Original Brownstone Group was founded by a trio of entrepreneurs - David Behin, Slava Halpern, and Michael D. Stern. Each of these individuals brought a unique perspective to the table, shaping OBG's philosophy and approach to real estate development.

David Behin, a graduate of Columbia University's Graduate School of Architecture, Planning, and Preservation, brought his architectural acumen to the table. Slava Halpern, with his background in finance and investment, provided the financial backbone of the company. Michael D. Stern, an experienced real estate developer, offered his expertise in navigating the complex NYC real estate market.
David Behin: The Architectural Visionary

David Behin's architectural background has been instrumental in shaping OBG's projects. He believes in the power of architecture to transform communities and enhance the quality of life. His designs often blend historical elements with contemporary aesthetics, resulting in unique, timeless spaces.
One of Behin's notable contributions is the conversion of the former P.S. 64 school building in the East Village into a mixed-use complex. The project, known as the "Citizen," retained the original building's historic facade while transforming its interior into a modern, eco-friendly space.
Slava Halpern: The Financial Mastermind

Slava Halpern's financial prowess has been crucial in OBG's growth and success. He has a keen eye for identifying promising investment opportunities and structuring complex financial transactions. Halpern's strategic investments have allowed OBG to take on ambitious projects that would otherwise be out of reach for smaller developers.
Halpern's financial acumen also extends to OBG's commitment to sustainability. He has been instrumental in securing green financing for several of the group's projects, reflecting OBG's dedication to environmentally responsible development.
OBG's Commitment to Sustainability

The Original Brownstone Group is deeply committed to sustainable development. The company recognizes that real estate development can have a significant impact on the environment, and it strives to minimize this impact through various green initiatives.
OBG's sustainability efforts are not just about meeting regulatory requirements; they are a core part of the company's mission. The group aims to create living spaces that are not only aesthetically pleasing and functional but also environmentally responsible.




















Green Building Practices
OBG incorporates green building practices into its projects, aiming to reduce their environmental footprint. This includes using energy-efficient materials, implementing water-saving systems, and incorporating renewable energy sources like solar panels.
For instance, OBG's conversion of the former Domino Sugar Factory in Williamsburg, Brooklyn, into a mixed-use complex includes a 15-story tower with a green roof. This not only provides insulation and reduces stormwater runoff but also contributes to the building's LEED certification.
Preservation and Adaptive Reuse
One of OBG's most significant contributions to sustainability is its commitment to preserving and adapting historic buildings. By giving old buildings new life, OBG reduces the demand for new construction materials and minimizes waste.
A prime example of this is OBG's conversion of the former Greenpoint Hospital in Brooklyn into a mixed-use complex. The project retained the original building's historic facade and incorporated many of its original features, preserving a piece of Brooklyn's history while creating modern, energy-efficient living spaces.
As the city continues to evolve, so too does the Original Brownstone Group. With a forward-thinking approach to real estate development that balances innovation with sustainability, OBG remains at the forefront of NYC's real estate scene. The group's commitment to creating unique, livable spaces that respect the city's history and environment ensures that its legacy will continue to shape the future of New York City.
