We did the same as you, moved from a nice spacious house with massive loft, built in cupboards and garage, to one with no loft space, no storage and no garage. Ironically, we did it to ensure our dcs would go to good schools - of course they are only good schools if your child doesn't have any SENs, but it's too late now .... 
Most of the stuff we stored was stuff we needed to sort through and either recycle or dump etc, but it meant it was out of our hair while we settled in and we could go over to the unit whenever we had a free hour and deal with it one car load at a time.
Need to hire another one now so we can shift things to decorate. We are so tightly packed in there's nowhere to put things from each room while we decorate - hence dd, now 3 years old, still being in our room, as her bedroom is still primarily a study/store room.
You're unconventional birth plan sounds interesting. I had one of those, right up until they realised madam was breech with low movement. Even had the home delivery pack and birth pool all ready, but apparently dd wanted to be born in hospital.
Ah well, at least I managed to avoid a section.
I wish you better luck and a much more compliant baby.
