We aim to see if these luminous, rare and distant galaxies are signposting dense regions in the early Universe. Our $870\\textrm{-}\\mu\\textrm{m}$ survey covers an area of $\\approx0.8\\,\\textrm{deg}^2$ down to an average r.m.s. of $3.9\\,\\textrm{mJy beam}^{-1}$, with our five deepest maps going $\\approx2\\times$ deeper still. We catalog 86 DSFGs around our 'signposts', detected above a significance of $3.5\\sigma$.
