On a New York island accessible only by 45-minute ferry from Connecticut, building a prefab retreat required brokering a deal with a ferry operator. Getting concrete mixers on and off the island by boat was virtually out of the question, so the architects specified a prefabricated foundation and arranged to put the slabs on the ferry with the help of the general contractor. The ferry operator confirmed that the boats could accommodate the 16-foot-wide modules that comply with federal shipping regulations, as long as the modules were arranged two abreast and delivered before Memorial Day weekend.
