I want to put a row of bookshelves along a corridor, immediately above door frames - basically like this above the doors. Because of the gaps where the door themselves, and because I assume floating shelves wouldn't be strong enough for long rows of books, I was thinking of "upside down shelves", basically like these. The walls are solid bricks.
Are there any downsides to doing it that way? Any other suggestions / ideas?
Thanks in advance
