Here are photos of the scaffolding that has been erected around 231 Duffield Street. While most attention has been on 227 and 233 Duffield, one important part of the history of the block is that all these buildings were connected underground. 231 Duffield is controlled by the V3, the same company building the hotel at 237 Duffield, and it looks like they intend to use their demolition permit. Some speculate that escaped slaves may have used other buildings on the block for various purposes, but that they stayed in 231.
