Considering the Time Period. I would go with 2. Taking into account that his Father was a Politician, and in that time period meant that he was a Mason or a Meso Druid (Not the same type as John), which was a means of making contacts and getting things done. He probably had underground tunnels. This was probably especially true considering his mother.
Number 2 looks like it has multiple types of secondary, tertiary, and quaternary support structures and reinforcements.
