This $2.5 million design-build project prepares a pad-ready site for a community of 50 tiny homes, an outreach center, and a community center supporting veterans experiencing homelessness. Castle collaborated closely with the owner and architect to create an inclusive layout that meets City of St. Louis, fire, and AHJ standards while aligning with the nonprofit’s budget. Addressing challenges like contaminated soils and old building foundations, Castle adjusted the grading plan to retain usable materials onsite, optimizing costs.   

Castle’s responsibilities included civil design, site preparation, earthwork, and soil remediation, along with installing 451 linear feet of storm sewer, 3,057 linear feet of sanitary sewer, and 2,782 linear feet of domestic water service. Additionally, Castle completed grading and concrete slab installation for the tiny home foundations.

"Working with Castle through a progressive design-build approach for site preparation, earthwork, utility infrastructure and tiny home foundations helped us get started faster and provided us with flexibility as we worked through this unique project for a tiny home village in St. Louis. One example is that contaminated soils were determined to be more extensive than identified after construction started. Castle was able to utilize their internal design team to collaborate and respond quickly, providing us with a remediation solution within the original budget."
