Our property to be renovated has a 1.26x1.26 window to the garage. I would like to replace it with a side entry door about 1.00x2.00. I don't see a problem in increasing the window cut up and down. But the window should also become narrower. The house was built in 1980 and is clinker. I am already trying to arrange the right bricks at the same time.
Is this action in principle relatively trouble free or will I get myself in trouble?
