That picture has made me think!
In some ways the house looks good to my eyes, but in others not so........
Maybe because I was brought up in a area in London with that style of building it lacks ' depth ' to my eyes.
It just feels two dimensional, the building lacks something.....
The proportions of the windows are good like you say.
But to me it has the feel of a pastiche.
Getting to your point about charts, like the house picture, if they don't 'feel' natural on viewing I tend not to trust them whatever scale is used.
Not sure that this will make sence to you guys...... : (
Thanks Sledge your post has helped my thinking.
