I hate to pour cold water on all this 19502 love (shudder)
but if the rest of the house is that dated, then so will the electrics and heating be that dated.
So you will need to go back to basics to update it, not just decor.
Personally I couldn't bear all that hideous glass walling along the corridor, but I suspect without it the hosue would become very dark.
Kitchen - I think it is a fridge, because to the left of it is the built in electric cooker? The counter top looks slightly different so I think it is an electirc hob.
The kitchen may be rock solid wood built, and salvagable, but a lot of post war stuff was crap quality
