Re routing soil vent

[T_dot_white]

Hello, we are in the process of refitting our bathroom and would ideally like to move the soil vent pipe outside to free up more space. Any guidance on how to complete this would be appreciated. Below are two pictures, one of the internal set up and one of the exposed soil pipe outside the bathroom.
Many thanks in advance

P.s the bathroom is in the ground floor as we are in a bungalow

Would it be possible to cut into the external clay pipe and put a saddle t coupler onto it and run the soil vent off of that? Then internally just cap off the vent?
Thanks in advance

Is the manhole nearby? you could run a vent from the manhole near the top through the side underground and then up a wall - not a good idea what you suggest

You would need to know if the glazed clay pipe extends further under the house or is the bathroom the only inlet. As Nige mentions you need to have that soil pipe vented or you could cause issues.

Id personally, (if the clay doesn't go any further under the house), cut it externally and fit a bend. Come up to appropriate height externally, and then tee through the wall to pick up the WC, then continue upwards outside to vent. Redundant drain will need to be removed and floor and damp membrane made good though.
