S.I. Container Build

What S.I. Container Build does

S.I. Container Builds is a privately held, women-owned modular construction company founded in 2016 by CEO Rory Rubin and headquartered in Buffalo Grove, Illinois. The company designs and fabricates sustainable steel-frame buildings using repurposed one-trip shipping containers, with an off-site precision manufacturing process certified by NTA-ICC for multi-state code compliance. Its product portfolio spans single-family homes, accessory dwelling units (ADUs), multi-family developments, workforce housing (P3 Construction Site Solutions), commercial structures (concession stands, retail spaces, marina amenities), and specialized facilities such as the She Care Wellness Pods deployed at HBCU campuses. Notable technical features include Corten steel construction rated for winds up to 175 mph, modular expansion and relocation capability, closed cell insulation, and solar integration through the SUPER GREEN Model, which is designed to maximize Inflation Reduction Act tax credit eligibility.

The company operates a hybrid go-to-market model: direct-to-consumer sales for individual homeowners seeking ADUs and single-family homes, and enterprise field sales targeting developers, contractors, government entities, and nonprofits for larger B2B projects. Revenue is generated through one-time project-based sales with quote-driven pricing that varies by size, customization, and specifications. Distribution is supported by a modular consultant network (notably Audree Grubesic of Modular Sure Site), partnerships with financing providers (PACE Equity Finance for C-PACE loans), and industry collaborations through the Offsite Dirt Network. The customer base is diversified across hospitality, real estate, agriculture, sports/recreation, education, nonprofit/social services, and government verticals, with flagship projects including the Navy Pier Marina amenities building in Chicago, multiple HBCU wellness facilities in partnership with the Boris Lawrence Henson Foundation and kate spade new york, and a DCFS-licensed group home for trafficking survivors in Palatine, Illinois. Production is anchored by a 32,000 sq ft facility opened in July 2022, with typical build timelines of 8-12 weeks and documented cost and sustainability advantages over traditional construction.
