Oaktree Development
Welcome to Oaktree Development
For over 40 years, Oaktree Development (formerly Unihab) has specialized in innovative, sustainable, mixed-use multifamily projects—many of them transit-oriented. Founded by architect-developers Arthur Klipfel and Gwen Noyes, Oaktree has led or designed more than 2,000 residential units with a commitment to high performance, social impact, and thoughtful urban design.
Oaktree’s companion firm, GreenStaxx (GSX), brings a patented modular building system to market, developed by Arthur Klipfel to streamline the design and construction of urban residential units. Using a digital library of pre-engineered unit stacks, GSX enables developers to build faster, reduce costs, and lower risk while meeting high sustainability standards.
