hi, the extension on my house was built in the 70/80s. there are breeze block walls dividing the rooms up downstairs these walls do not continue up stairs they are all plaster board.
i want to knock one of these walls down to open the room up. I have removed part of the ceiling and have noticed between the beams and the breeze blocks is plaster board. this made me think that the wall had been built after the completion of the house.
Not sure how well i have explained all this, i have photos which will hopefully do it a bit better.
thanks
