There are MOCs utilizing whatever pieces at hand to create something unique and then there are alternates using only the parts included from a set to build something else. This thread (I have wanted to start for a while now) is meant to showcase such designs to help inspire your own well as display what can be done within such limited means. Anyway here are a few to get started.

Note:
While the main point of this topic is primarily the usage of pieces within a single set to create a different model shown on the box, the mixing of two or more sets is permitted but the final product must only use those included pieces. Please list the set number(s) of any alternate design posted.

Was all set to deconstruct and sell my Tower Bridge but this is a very nice alternative that's just popped up on rebrickable.

Wow. I’ve got a Tower Bridge I recently picked up cheap. I was going to tear it down and sell it off. But after seeing that, maybe not. That looks really nice.

Interesting. I've been tempted to buy some MOC instructions in the past, but the BL parts costs has always may me shy away. Something like this I can definitely go for!

Only $20 for the instructions. Good deal.

Another neat model.  I bet there was a lot of pieces left though.
