Sorry this is going to be a long one... but I hope you bear with me.
The left is what we used to have, the right is what we are going for.
I have completed the small bedroom (Bottom right), and the large bedroom (bottom left).

Just to note, the two little rooms next to the old 'big bedroom', was a built in wardrobe accessible from the large bedroom, and next to it was a room with just a toilet and a sink over the cistern.
We've knocked that through so that the landing now goes to the back of the house. We only had a toilet here before, so now we want to have a proper bathroom. There is a cold + hot water feed accessible easily under the floorboards. The issue is the soil pipe.
Here is a photo of the outside of the rear of the house:

And imposing where the stack and branch to the old toilet is so people can get their bearings:

With these pictures I'm sure you can now see my difficulty![Big Grin :D :D](/styles/default/xenforo/vbSmilies/Normal/biggrin.gif)
Here is inside upstairs, you can see the window and where the pipe comes in for the old toilet. The vertical line of exposes bricks is more or less where the existing soil pipe is on the outside.

You can see the two stud walls either side of the end of the landing, we also want the window to be centered at the end of the landing, but that's exactly where the stack is.
So I see only 1 option, and that is to bring the pipe inside as close to the 1st floor floorboards and run it vertically internally and vent out the roof.

Any other ideas?![Big Grin :D :D](/styles/default/xenforo/vbSmilies/Normal/biggrin.gif)
TO be clear I would remove everything that is external now that is above the crappy black drawing in paint in the above picture - to allow for the window at the end of the landing. It would then go inside, vertically and out the roof to vent. Is it ok to have a horizontal run in the main soil stack?
