GreenStaxx is a breakthrough solution for modular multifamily construction. The patented GreenStaxx system provides a library of sustainably pre-designed and pre-engineered units which are stacked and configured into a grid that is flexible to maximize the development of any site. When a project is identified, a grid is created to fit local conditions and sized to fit the unit stacks. When units are placed into the grid, the result is a completely integrated set of contract documents that are connected to supply chains, including modular manufacturers. Utilizing the GreenStaxx building system, teams at the local level, site owners and developers can quickly and accurately evaluate sites, generate entitlement and construction drawings, and decrease construction time while maximizing building potential and quality.

Like toy blocks, the stackable GreenStaxx library of unit types include outside corners, inside corners, units with stairs, a unit with an elevator shaft, one bedroom units, two bedroom units, etc. This library of unit types provides the data and documentation to quickly and easily design, evaluate, estimate and construct high quality, energy-efficient multi-family residences.

The GreenStaxx system has been used in both modular and traditional timber frame multi-family, residential and mixed-use projects ranging from 35 - 280 units. GreenStaxx is now focused on the symbiotic advantages that modular construction provides in combination with the GreenStaxx system, particularly in urban, mixed-use or multi-family residential projects.
