That looks like a nice bench... But as the guys said, right off you are gonna loose at least one drawer. I too would be conserned with redgidy and Wiley makes a great point about the shelf. A eye level shelf for your scale is a really nice thing and if your bench is not rock solid, mounting it seperate form the bench top is necessarry. Absolute rock solid mounting for the scale is needed for accuracy.
Personally, for such a small space, I would build a bench off the walls inside the bench. 2x4's screwed to the walls then a double 3/4"plywood top will be rock solid! For the top cut it directly in half to get it in there. For the first "top" cut it front to back. Then the second top cut it side to side. A shelf below can be done the same. and a shefl above can be like Wileys or again more 2x4s (or smaller stock)and a smaller sheet of ply wood. If you do build it, don't skimp you really do need a double top for regidity. Single shelves of 1/2 ply are probably plenty thou if you want to save a couple coins.
EASY to make, EASY to remove with MINIMAL damage to walls. (Five minutes with a shot glass full of spackle) Best of all bet its cheaper than $220!!
Good luck,
