Reconstruction of the downstairs back wall is complete, hooray!
Kitchen will be on the left, dining area on the right.
Feels like progress.

Flexible wood fibre insulation batts fills between the studs (in the timber frame).
This ‘stud wall’ has been finished with large sections of plasterboard, ready for a skim coat of plaster (not by me).
The exact build up is in the previous post here.

• Most of the old, cast iron soil pipe (toilet sewage pipe, running internally down the back wall) was replaced, to rearrange & re-plumb the bathroom above.  Now boxed in.  Packed with wood fibre batts, also to muffle the sound.
• Waste pipe for kitchen sink connected.
• New cold & hot water pipe runs to & from upstairs, a better route for connecting to the new hot water tank, up the left hand wall; now inside the wall
• water supply pipes for the kitchen sink, hopefully in the right place.
• intruder alarm wires threaded
• garish wall paper stripped – and it feels calmer!
• 2 colours of Osmo wood oil stains tested on hardwood plywood.  Honey or Amber?
• Kitchen delivered.

Next steps:

• electricians return to wire kitchen, oven switches etc.
• plastering top coat
• meanwhile, the front wall
• then, allen keys at the ready.
