I started on a single site but enjoyed it immensely as I was general labrador as well which meant in these days anyway, you did a bit of everything not just sweep up after all the trades. My second stint was again house bashing but as a full time scaff and have to agree with every word Dangeruss posted. Now as a gaffer I would say that it is on it's erse at the moment but will soon enough return to more normal levels. We do have plenty on but the new builds were our bread and butter in the early days and never really got bored again as there was always something else to break it up with but I do miss the days of the empty yard and the easy square box fully boarded.
