To bump out 2' to the front is well worth the money,
when you go out 4' or more to the side thereby requiring a larger premium lot it gets pricy.

The attic will offer space but

The space can be maxed out better with cabinets up high both on and off the floor like 4' from the ceiling, put on 3 walls that can be a ton of storage.

There are storage places nearby for less than $50 a month.
