So new it doesn't seem to be on Google or Bing Maps yet, at least on the actual map bit, this is the one new build that stands alongside the two historic-building-conversion jobs (Purifier House and Engine House) at Brandon Yard, basically the site of the old gasworks.
They were one of the last sites to be regenerated, after some failed attempts to turn them into offices, including by the Soil Association. I don't know much about what they do in a gasworks, but I heard that the ground was highly polluted and needed a lot of remedial work before anything new could be put there.
