If you house's sewer pipes are connected to your neighbor's IC (that is, a shared IC), then your lucky star is shining through.If you have bought your neighbor's house instead, because its IC is shared, then the location of this IC is more or less fixed. In rebuilding a new house, or an A&A, the house would have to be designed around the location of the IC basically. Which is why we could occasionally see an IC located at the oddest places in a landed; at the kitchen walk way, inside a bedroom, beside the dining table etc. Cheers!
