To brick or not to brick

The back of the house upstairs was going to be concrete panelling because the downstairs wall wasn't directly underneath supporting the weight. However we have decided to stump up the extra cash and build in brick at the back depsite noone being able to see it. Concrete cladding at the back is just not going to be a good look. We have also change the window size from those think 60cm high ones, to full height, hoping that the neighbours don't complain about us overlooking their plot.
