How long would it take to build lodging?
Houses could probably be built in a fairly short time, as they worked with extended families aiding in the building process. For a permanent building it might have taken a week to gather the material and another week to build the house. When they were traveling they used tents which could be set up in minutes. These could also be set up on their ships for protection from sun & weather. As to how many men it took to build a Viking age house, like today’s homes, it could be built by one man, but would take a long time. The more men (or women) able to help build, the faster the house would go up.
