The soil pipe is quite a way in from the wall, 6" with the centre
being 9"
https://flic.kr/p/2qTDSg1
We're looking at having a new toilet as part of a bathroom
refurbishment and the suggestion is just to build a stud box.
There are floorboards under the carpet. Is it usually a major
exercise to have the pipe nearer the wall? 1968 build.

Is this on the ground floor?
If so does the soil pipe go up to a second floor, or if a bungalow up
through the roof to be ventilated?
From the photo - is that the base of the toilet next to it and if so
how is the outflow to the toilet connected to this soil pipe?
The lower part of the soil pipe appears to be clay and possibly to move
it a PVC extension and new PVC sweeping bend would need to be fitted
under the floor. How much work this would entail depends on what is
under the floorboards and how many floorboards would have to be lifted
to gain suitable access. The soil pipe under the floorboards may be
buried under earth or may be in a concrete foundation raft.
You may find that the builders have brought the soil pipe up beside the >concrete footings which could/will extend much wider than the inside
wall of the building.
Joining plastic to clay is much easier these days than in 1968 with
something like >https://www.screwfix.com/p/floplast-underground-flexible-adaptor-120-136mm/19914?
If the soil pipe goes through a ceiling to another floor or through the
loft ideally that location would also need to be changed. A new hole
through the ceiling. If it just goes up afterwards though the roof then
a bend could be placed in the loft to avoid messing around with roof
tiles etc.
If a soil stack goes out of the roof and alternative may be to use an
air admittance valve. >https://www.drainagepipe.co.uk/soil-and-waste/how-to-use-an-air-admittance-valve/
Are you planning to re-route all those other waste pipes if move the
waste pipe.

No, it is a bungalow.

Sorry for not being clearer. The toilet itself is to the right and
contains the 'U' bend which terminates in the clay 'pot' that you see
in the photo. That then goes underground. The outside of the
bungalow is the wall on the left where the measuring tape starts from.

To be clear the intention/hope was to move it to nearer the wall so
that a new toilet would be flush with the wall and not leave the best
part of a 6" gap.

It doesn't as explained above.

The soil stack is not involved. We seem to have a strange arrangement
where the sewage system is shared between adjoining properties and in
our case the stack is attached to the detached bungalow that is to the
left of the photo.

waste pipe.
Shouldn't be necessary, they all go into a drain the other side of the
wall.
We had a similar toilet in our last house where a kitchen extension was
built on the site of an old wash house and exterior toilet the toilet or at least it’s waste plumbing was retained and a new toilet was included in the extension. Like yours the clay waste was some distance from the wall and necessitated a separate cistern connected to the pan with a flush pipe. As
I said before it is going to be an expensive job for little gain and basically it means you cannot use a close coupled toilet.
