Okay, imagine Tom Bender is like a grown-up who designs buildings. It's kind of like drawing a really cool picture, but instead of just being for fun, the building he designs is a real place that people can go inside and use.
Tom Bender has to think about lots of things when he's designing a building, like how many rooms it will have, where the doors and windows should go, and how people will move around inside. He also has to make sure the building is safe and strong so it doesn't fall down!
Once Tom has all his ideas down on paper, he works with other grown-ups who help him make the building actually happen. They use special tools and materials to build the foundation, the walls, the roof, and everything else that goes into the building.
When it's all finished, people can go inside and use the building for all sorts of things, like living, working, learning, or playing. And all of that is thanks to Tom Bender - the grown-up who designed it all!
