Yes you can! There is an amazing voluntary project now in France. Where one investor bought the land and people volunteer to help build a castle on it. The people gain knowledge of past building techniques since there are no motorized vehicles or electronics allowed. The lumberjack drives his horses into the woods and cuts the trees used for lumber by hand. The blacksmith makes the tools, and the stone and clay is gained from the nearby quarry. Here is the link: https://www.guedelon.fr/en/
The castle will take 25 years to complete!

Do I have your permission to use that in a conversation? I’ll seem smart!
