All the water and heating pipes have been run, and will be
hidden behind skirting and insulation board.
The lobby/dressing room area won't have the full-height sloping ceilings so the
stud wall has been insulated against the cold void which will be behind it.
The dressing room area will be lit during daylight by a sun pipe. That's a highly reflective pipe that links the ceiling with a hole in the roof covered with perspex to let in daylight.
Things are starting to look nice and tidy around the skylights. The ceilings have foam board insulation between the rafters, and are further covered in insulated plasterboard.
