hi, i bought an ex council house that was rebuilt due to the old cancer issues and it was the only way the previous owner could get a mortgage. its been a process of doing it up bit by bit over the last 9 months since i moved in . today i was putting a new door frame in upstairs when i discovered that either side of the door was a vertical concrete column and a lintel at the height of the rafters . i have the kitchen gutted as its getting replastered tomorrow and upon inspection it seems that all of the stud walls are made from verticle concrete columns rather than wood. my question is that i am thinking of moving a wall upstairs to enlarge the bathroom but now i have seen all of this strangeness i am having second thoughts, does anyone have experience of these houses and how they are constructed, i dont really want to trash all of the walls just to have a poke around , not yet anyway ,thanks.
