Hatch size and boarding set the crew's pace
Georgian and Victorian terraces across inner London commonly have a small hatch and unboarded joists, which means crawl boards have to go down before anyone can move safely, and every item is passed hand to hand rather than walked to the hatch. Post-war and new-build stock in outer boroughs more often has a boarded loft and a proper loft ladder, which is a noticeably faster job for the same volume of contents.
