Soil stack question

How hard and expensive is it to move a soil stack. I have one approximately 1.5m from the front of the house (down the side) and wish to move it to the front when I put a garage on the end of the property.

I don't want to start the garage 2m from the front of the house as I feel it won't look right, and will add issues if I ever put a second storey on top of the garage.

On a side note, how hard and expensive is it to replace the sewerage pipe running down the side of the house from the soil stack, as I may need to put it deeper in the ground once I start excavating?

Thanks in advance

Not as easy as leaving it where it is
You can have a foul drain passing through footings; it's allowed.
Might be a bit nasty having a stack in the new living room but not much bother in the garage surely? You could box it off with plywood if its an issue.
You can easily weather it where it exits the roof.
Get's done all the time.

Would rather it stay on the outside of the building, just in case I want to put a second storey on at some point!

They do have them inside you know
Sometimes it's better depending on what you need to connect to them.
I smell a living room

Moving stack is not so hard. You'll need to dig up the ground over the drain.
Just connect to the drain further along bearing in mind that you will need a manhole/ inspection chamber (depends on how deep the drain is) wherever it changes direction. Surround the drain in clean chippings (the right kind; there's regulations) and back fill. You'l need to protect the drain if its under where vehicles go.
Biggest problem usually is reconnecting whatever there was originally connected to the stack where it was before.
You need to be able to rod all the straight runs through access points and each run has to 'run' so that the foul water drains away.
Theres regulations about how much 'run'.
Cant give much more advice without knowing what the exact set up is ...

I'll photograph the stack/area and doodle some diagrams, and put them up over the weekend.

Here all above ground drainage is inside to stop it freezing, and its not a problem, just either boxed in or hidden inside the wall.

Knowing where the drain that the stack leads to would be useful..

At last!
Somewhere thats colder than us!

Most new builds now are inner soil stacks, theres nothing wrong with it, as skeetly said leave where it is if poss.
Getting the correct run is crucial, our building inspectors are quite lenient, i know there are regs about runs and access / rodding points but they will let you get away with some as long as 90% is ok.
I find drainage easy, i hate the digging to expose the existing, cant stand digging, especially clay soil.

I dont know we are at +4 at the moment. I still cant get my bike out though as we have at least 75 mm of ice on the side roads. Looking forward to April!
