I think that the anchor represents the mother and the kite represents the son because the mother is holding the son back when he was younger and now that he hasaid his own house he feels free like a kite is in the air.

‘You at zero-end,me with the spool of tape,recording length, reporting metres, centimetres back to basics the leaving up the stairs’ this quote could be saying that maybe that now him and his mother are going in different ways because it says leaving up the stairs could mean she is leaving forever.

When the son was smaller maybe he was entirely allowed to meet his friends or have people over and now he has his own house he is free.

“The breaking point” this quote can mean that maybe the son and mother have had a lot of fights in the past and this house is the breaking point of the fights and is going to separate them forever because his house his really far from his mother’s house.
