New connection to deep manhole

[noseall]

Very rough sketch. House wall in black. Existing deep sewer runs right to left. Existing pipes from house in blue; proposed new pipe in red. Ground is slightly lower to the left.

Connecting to an existing pipe would require a sharp left turn (probably tighter than the diagram suggests). I don't know where the existing pipes drop, i.e. whether there is a backdrop at the manhole or whether they run at low level from the house. Joining to them low down would involve a deep excavation; joining at shallow level might require running up hill.

Smashing into an existing benched, masonry IC is not going to be easy to make good.
We'd likely opt for our own plastic IC grafted onto the closest blue line to the new run. No need for permissions then either. Like we did below when fitting new drains (downstairs loo etc) to a new extension. The architect had specced going into the existing IC but my way was simpler. The original IC is right by the barrow wheel.....
