Principals Yiannes Einhorn and Hal Einhorn founded Grid Group around a shared understanding that things done well create value.

Building on decades of design, construction and financial experience, Grid Group offers a full suite of real estate development services and a dedication to quality and craft above all else.

Our projects are a reflection of this hands-on commitment, where classic design proportions, masterfully executed construction details, and a comforting sense of refinement remind buyers and investors alike that there is a right way to do things. With deliberate and meticulous attention to detail in each stage of the development process, we take pride in creating exceptionally well considered and expertly crafted spaces for our customers to enjoy their lives.


Yiannes Einhorn

Yiannes Einhorn is a doer. With the bandwidth to carefully balance countless priorities and prerogatives simultaneously, an unending curiosity of the how and why, and laser focus on creating the best possible outcome, Yiannes is a master of getting things done, and done well. After cutting his teeth at an early age in the home inspection business observing countless building system failures, Yiannes began to translate those experiences in the form of construction detailing and design in each of his development projects. Never afraid of a challenge, Yiannes has applied his encyclopedic knowledge of Zoning and Building Code to quickly evaluate prospective deals and find opportunity not visible to most. Currently overseeing the design and construction of more than $300 million in project value, Yiannes’ hands on approach and exceptionally high standards for the people that he works with have allowed Grid Group to maintain the highest of standards in quality and craft in the New York City new development market.
