No they are not blocked, the bottoms of the windows are an inch or two above the tops of the cabinets. The master bedroom is on the other side of that wall.
Lamar,
Forgot to mention that is a very nice job and blends with the house nicely. I'll bet they are very happy with the job.
I would paint the high windows the same color as the wall though, they compete with the cabinets.
regards,
