Seeing this photos/picture surely modern architects should blush.
(for something outraging, a building or bridge that collapsed or some awkward project).
These pictures should make comtemporary/modern architects get red with envy. It´s such a good job!
Here the modern architects shoulld get some more training and/or learn something from the old guard, so we are praising the old grand structure that is working well, along with being a beautiful building job.
Ashamed would be a strong statement, but grammatically correct. It could be almost as if we were berating someone else for something! But there are cases in which we would say such things...
