This is a so called Kontor Building from our Leniland Bedrock Server. (Minecraft Java & Bedrock 1.19)
Paste it where you stand. It faces north. If you are using WorldEdit please use [//paste -e] to also paste the entities like armor stands etc.
The Building has a basement, so when you paste, it goes 6 blocks into the ground below your feed where you are standing.
It is one of many pieces of the Leniland Bedrock Server, making it possible to create your own adventure map.
