In our case, we worked with Hi-Tech Housing of Bristol, IN since they are specifically a custom modular manufacturer, No stock plans here–you just take them whatever you’re interested in building, and they help figure out how to break it into chunks that can be transported on trucks. Once the modules are ready, a “set crew” and crane operator are hired to put it together in the field. (more…)
