I live in a typical two up two down house with a rear extension with the bathroom at the back of this. The bathroom being at the back makes for some chilly winters mornings so I intend to move the bathroom to the back room of the downstairs of the mainhouse so that I have a walkthrough corridor through the house to the rear extension that will become kitchen/dining area.
The side alley is clear and I am hoping to build outwards (prob next year) into this alley to make the rear extension full width to the garden end with a light well to the bathroom in the middle of the house.
My question is as a competent DIY'er is the laying of the drain and an IC (none yet, presuming just a collar onto main sewer in garden) something that can be done. If I am required to lay the new drain up the side too deeply then I would be relcutant due to the risk of disturbance to next door and own walls. What is the minimum depth that the new pipe could be laid?

Minimum depth is dictated by invert levels of the system to which you are connecting.
In theory, the new pipework can be laid at any level, even above existing ground level, as long as there is sufficient fall. In situations where the pipework is exceptionally shallow, we always encase the pipework in concrete, for protection. I would suggest that, unless you have at least 450mm of cover, you should consider the concreting-in option, just in case some eejit decides to dig up the ginnel in years to come.
