The Big Build recreates historical landmarks from Viking longboats to a prohibition-era speakeasy from the 1920's. Other creations include a medieval castle tower, a historical coastal lighthouse, and a Lewis and Clark vintage winter fort. Host and contractor Nick Mystrom enlists the help of experts from some of construction's most esoteric fields as he puts his hands on history. You are walked through the step-by-step process of the challenges faced by the original builders, and the amazing engineering they had to use to enable them to overcome their obstacles.
