The Big Build at the National Building Museum

A free, all-ages family festival where kids and grown-ups learn hands-on skills side by side with real tradespeople: plumbers, carpenters, roofers, electricians, and designers. Children use real tools to hammer nails, wire a light, and pour concrete, and can climb inside construction equipment at the outdoor truck petting zoo. It is a drop-in day built for curious families who love making and building things. This event was created as a sample for the Family-Friendly Events community events. It is (or is expected to be) a real event, but the details and date may not be accurate. Please check the official event website for the most up-to-date information.
