I own a semi detached home and ran into problems installing the shelving. However, Id buy this again if I could put them into the spot that allowed them to be properly installed. 

Floating shelves are beautiful but I did not realize the kit had such intense hardware. So Im having difficulty putting the shelves where I want them. 

That second pic is a firewall and I cant use the hardware, but without this hardware the shelves lean forward on a slant. So, not ideal, even though I love the look. 

Now, I have to fix the wall and find a way to use the shelving on a fire wall.
