I was walking around here at the weekend (from the barrage, through "Toytown" and to the rail station) but haven't had chance to update the map yet - the building to the right of the marker has a relatively new sign on the Yale Crescent side: "Infinity House". There was a sign at the Sorbonne Close entrance with the same name when I passed a couple of years ago too, so I assume the whole complex of four buildings has this name.
