One of the delights of Boston multi-family architecture is the ubiquitous built-in china cabinet. Ours happens to be in the brightest room in our apartment so we decided to accentuate the light and the wonderful bowed windows across from the cabinet by placing a mirror in the hutch part of it...
Incidentally we had an older Ikea mirror whose width fit the space perfectly. Unfortunately the height leaves a gap at the top which is begging for some interesting decorative touch, which we haven't settled on yet.
The mirror really does make the room feel like it's surrounded by windows on all sides. You'd be surprised how many guests have confessed to being fooled at first glance into thinking there was actually a window in that spot. Granted, it only takes a few seconds to figure out the reality.
And for those who will groan that we've placed a couch in front of the bottom portion of the china cabinet, you've been warned before that we have an outside-the-box penchant for blocking things...like doorways.
Any thoughts on what you would do with the gap above the mirror, within the bookcase?
