There's cracks in the plaster of no.1 child's room, directly above the RSJ resting on the RSJ of the kitchen / side return combo extension.

Rightly so.
Mate has a monster house from early C19th, and partner wanted a more open plan kitchen. For years everyone told them it couldn't be done, then someone somewhere suggested this company that could take out the wall and install a steel instead.
I know this house, and I know this wall, its 4' thick or more, right in centre of house on ground floor, literally THE most central, heaviest, chunkiest wall in the whole place with 2 further full floors on top of it, and 1st swing of staircase joists on the corner of it. Not something to mess with.

Yup, got this magical company in to do it. And they've been living in a house that very closely resembles the game of pick up sticks ever since. Full internal and external bracing to hold onto what hasn't already moved drastically, become a bit of a legal battle, but ultimately the poor house is screwed.
