After looking at these images posted by others on voat of Pegasus, I am starting to believe Pegasus may actually have a large space below the building. Please refer to the photos below posted on Voat by other members.

Also, keep in mind. The park two houses down used to be a Trolley turn around. Any chance of stuff underground around here historically?

Where is this picture from in Pegasus ? https://i.sli.mg/twRY6g.jpg I don't see any other concrete ceilings in the building. This picture makes me think the first picture is a basement. (look at the white tube) https://i.sli.mg/Tg1EzT.jpg

Also, Here they are pouring cement. on the bottom level. Take note of the wire grid, usually used to reinforce. Why would you reinforce cement on the floor if there weren't a basement? Anybody here familiar with laying concrete flooring? is this normal?
