A foreign team called Build the Earth - UK recently shared the entire UK they currently reproduce in Minecraft in 1:1 ratios.
Based on the team's newly released intelligence, we can see the Wales Llandudno Pier in production, as well as the city of Newcastle near the Scottish border. While the team didn't say how long it took to build, according to its video channel was created in July 2020, it suggests they've spent at least nearly two years.
In Minecraft, a 1:1 restoration of the entire UK is a feat, and players are expected to have to wait a long time to see the finished product.
