Firstly, hello everyone. I am new to the forum.
I am about to embark upon a self build extension project, although not really "self build" as it is my other half's dad who is to be doing most of the work having been a bricky for such as Redrow etc up until he "semi retired" a few years ago.
I'm not going to teach my grandmother to suck eggs but for those of you who are unfamiliar...
The house is a Wimpey no fines which was built using shuttering and poured in situ concrete, which consists of only concrete and aggregate with no sand (hence the name no fines).
So the walls are basically a solid mass of grey concrete full of pebbles like a giant rice crispies cake!
Does anyone have any experience of knocking through on this type of non standard construction?
Part of the extension is to fit a UB and remove the outside kitchen wall (approx 3.4 metres).
As it is a solid mass, would it still be necessary to use strongboys/acrow props at the back of the house or will the mass of concrete be stable enough to just support the ceiling on the inside whilst cutting a slot and fitting the beam?
Not sure if it makes a difference but the joists run parallel to the wall in question and one side of the kitchen is the gable wall, the other is a supporting wall between the kitchen and living room where the joists from both rooms overlap said supporting wall.
Any advice appreciated.
