Adjunct Assistant Professor

M.S. Real Estate Development

Alex Barrett is a native New Yorker, a licensed architect, and dedicated to the belief that great design adds value. Prior to joining Hudson in 2021, Alex founded and led his own architecture/development firm in the creation of multifamily condominiums in Brooklyn and Manhattan for 15 years.

He has been a speaker at the Yale School of Architecture, Harvard’s Graduate School of Design, Columbia’s Graduate School of Architecture, Planning & Preservation, and NYU’s Schack Institute of Real Estate and the national convention of the American Institute of Architects. Alex received a Bachelor of Arts from Connecticut College and an Master of Architecture from Yale School of Architecture.

Alex is a devoted gearhead and when he’s not creating buildings you’ll find him rock climbing, traveling, and exploring the city with his family.
