Multifamily Building Designs.
Ready to Go. 

Speed. Simplicity. Sustainability.

The GreenStaxx (GSX) System is a patented design tool with an innovative approach to driving efficiencies and satisfaction at every phase of multifamily housing construction.

Our standardized, replicable unit designs and in-unit specifications allow developers to build high-performing, healthy buildings more quickly and at lower cost.

We partner with construction managers, modular manufacturers, and architects dedicated to advancing innovative, efficient construction methods and streamlining project delivery.

GSX Library

GSX’s Library of modular-ready unit designs have been meticulously engineered to offer the best living experience for unit occupants and the best return on investment for developers. 

 

The library includes optimized corridors, inside and outside corners, and ADA unit designs that fit together like Lego blocks to form buildings of almost any size or shape.

 

GSX’s standardized outline specification integrates a supply chain of high-efficiency products and top-quality materials so that healthy, sustainable homes can also be the most cost-effective while leaving room for customization where it matters. 

 

Our process is optimized for modular manufacturing, but conventional construction is an option with the GSX System.

GSX has delivered hundreds of high-quality, human-centered, cost-effective units. Let us help you deliver more homes with less hassle.

Gilbert Trudeau, RCM Group

“GreenStaxx unit designs are some of the most well-designed living spaces RCM has built in our factory. Not only is the team great to work with, I believe their work towards standardizing building components represents the future of the industry."

John Boynton, Developer

"The residents of Brookside Square Apartments continually voice their appreciation of the units and the thoughtfully designed common areas of the building. This mixed-use building has become a centerpiece of the West Concord community. I would definitely contract with GreenStaxx for future multifamily development."

Scott Vlasak, BHR Architects

"As architects, BRHA appreciates the efficiencies that GreenStaxx Unit Library and Specification brings to the design process. It makes our job easier - from clarifying initial designs, to reducing rework - and allows our team to focus on bringing value and creativity to the parts of the building where it matters most."
