GreenStaxx provides a library of modular-ready, multifamily unit-designs that fit together like Lego Blocks creating building-designs of various sizes and shapes. Using our generative-design system, multiple building-design iterations can be created in hours for review as to massing configuration and site location. Also, each building-design iteration features a dashboard providing financial data to a level of return-on-cost.

Unit-designs are standardized to enable integration with off-site modular fabrication. However, within guidelines, both unit designs and specifications can be customized to fit local conditions and user preferences. And the specification is linked to supply-chain coordination. Unit designs are taken to a CD level. Although units are dimensioned for modular construction, at the user's option they can be converted for conventional construction if an acceptable modular option does not exist.


  • An added service Architects can bring when marketing their services to clients. They can offer a modular design option, massing and feasibility studies, and standardized unit-designs for clients use in multiple projects,
