About GreenStaxx

GreenStaxx is a Cambridge-based design company focused on applying the principles of mass production, standardization, and replicability to the modular design-build process for multifamily buildings. We see these principles as the key to lowering the cost of housing and enabling a quicker transition to low-carbon and responsibly sourced buildings. 

GreenStaxx began as a passion project within Oaktree Development, a multifamily developer specializing in designing and developing innovative, multi-family, mixed-use, mixed-income, high-performance, and transit-oriented (TOD) projects.  

While working on designing multifamily residential projects, Arthur Klipfel, CEO of Oakree and GreenStaxx, noticed that most residential buildings are comprised of stacks of units that repeat from building to building: outside corners, inside corners, and corridor units. He believed this repetition could be captured to create an iterative system for designing and constructing residential buildings.

Arthur developed and patented the resulting system, which became the foundation for GreenStaxx, which aims to offer the resulting process to residential developers nationally.

Our Guiding Principles

We seek to play a major role in enabling the most energy-efficient, well-designed, high-quality, cost-effective, and replicable multifamily housing available in the US. We intend to do so with integrity, generating positive professional relationships, making responsible material and energy choices, and advocating for sound land use principles and good labor policies.

We are committed to continuous improvement and transparency with partners and clients. The team approach requires continuous participant feedback to achieve cost and performance goals.
