Rebuild of Victorian end of terrace flank wall

[RobDIY]

Is an entire rebuild of a flank wall something to be avoided? I know it's possible but no idea how long it takes or cost? May need to be done due to movement/subsidence.

Have offered on an end of terrace late Victorian house in SW London thats in need to lots of renovation, but could be amazing and actually affordable (just about). Its been empty for a number of years and is in a bit of a state. Full survey has come back and said that the flank wall (its an end of terrace) has had significant movement with bulging at ceiling of first floor level and large gaps (up to 25mm) between inside of flank wall and internal walls. Cause of movement not yet clear, but we're doing a drainage survey and structural engineer report to get detail. Structurally the rest of the house is in sound condition and although slight signs of movement, nothing unusual for a house over 100 years old.

If the wall was rebuilt and new footings dug, would that solve any insurance issues? We've not yet been told its down to subsidence, but definitely movement and will at least need to be tied in.

We were thinking about extending out sideways and at the rear of the house, so could do this while the wall is down and planned on renting elsewhere while work is being done. Also likely to use someone a bit more specialist than just an extensions company.

If anyones had experience of similar, I'd love to hear your thoughts. Sorry for the length of post.

Thanks

Almost anything can be done to a house including moving the whole thing - providing somebody pays.

So, yes, there's no problem in removing a flank wall and extending the house footprint, and even underpinning during the work.

There's a mass of variables to take into account for what you say is existing and proposed. If you are serious then you have a sharp learning curve so perhaps crack the web sites like this - do a search - and read the literature.
Talk to an architect, and lightly consider how your final finish would look

You would have to appoint a site supervisor for the prelims & duration of the work.
