Omigawdyes. The previous Zaba residence was a 1920s semi, mostly rewired
prolly sometime round the 70s judging by the vintage of MK socketseses.
Took a few goes to get more proficient at wiggling cable out of the bottom
section of plaster from halfway down behind the skirting board to the
sockets... yuk! Tradeoff in the new place is all-stud walls (a win for
cable routing) but chipboard sheet floors (a lose for floor lifting -
have taken to plunge-cutting traps with a circular saw now rather than
trying to lift whole sheets; a blessing on the builders who marked the
routes of CH pipes and leccy cables on the chip as they laid the floor).
