The video shows a first-person view of a player in a sandbox game, likely Minecraft, building a structure. The player places red and black blocks on a grid to create a tall, narrow structure with a window. The player then adds a second layer of black blocks on top of the red ones, creating a two-story building. The player continues to build the structure, adding more black blocks to create a larger, more complex building. The video ends with the player looking at the completed structure, which has a tall, narrow shape with a window and two levels.
