Fwiw, I'm looking at that (from my "
amateur house builder's" perspective) and I'm seeing,,,..
- Dense concrete blocks. So presumably the least impact approach will be to cut along all four lines with a Stihl saw. Because of the enclosed location, the dust from that would be almost impossible to cope with, so they will presumably use the water sprayed blade. If so the brick walls & flooring (and everything else) will need to be comprehensively protected (or removed first).
- The three blocks under the 13a socket will be unsupported, as soon as the hole is cut. Presumably the "Hole in the wall gang" will securely stabilise that entire 5th course before they even ask for their first cups of tea.!!
- The 13a socket has no obvious source of supply. Logically it will be fed from above or behind, however a feed running up would also have been a compliant installation.?
- Lastly applies to after the "dust has settled" and your extra clearance is achieved. I appreciate that your driving skillz are proven to be of a level that most of us only achieve whilst asleep & dreaming, nonetheless your clearance will still be very close. Do you have some ingenious method to ensure the millimetre accurate positioning that will avoid damage to your awesome new Blower.??
