Building Pests and Shrinking Storage

We are one step closer to moving. The building and pest inspection was today, and there are a couple of things that we need to do, but the house is in pretty good nick. It's a cute house. Cute being the operative word....as opposed to grand....or spacious. Basically, it's a dollhouse. At a rough guess Id say we're working with probably 2/3 LESS space than we have at the moment. That doesnt really bother me, except for the fact that as yet, we have no outside storage. We will have....just not quite yet. Number 1 with a bullet on my MUST HAVE list is a storage shed...a big one. I collect two things...Harry Potter stuff and alternative dolls. Both of which take up considerable real estate here, and neither of which will fit in the dollhouse. I have been deep diving Pinterest in search of something similar to Hermione's beaded bag with the undetectable extension charm, so that i can hang it over the doorknob amd still access all my stuff. No dice. I'd love to be able to display all my Potters, but i lack enough bedroom, and the house lacks enough ANY room. As for my monsters, they'll be staying in their coffins until my Pinterest search pays off.
