anti-hoarders is right.
the empty, flattened boxes in our foyer were in a stack about 4' high, and about 33% of the 2 car garage was taken up with clothing boxes full of packing paper.
we moved into a larger house with less storage space. we were using bedroom # 5 for all of the overflow (told the movers to just put stuff there "we'll just sort it later"). DK has done wonders with that room - it went from 90% of floor space covered, more than 50% up to the ceiling to about 30% of the floor space covered, stacked waist high or lower.
if it wasn't all packed in boxes/storage tubs, and we threw in some rotten food, roaches, animal feces, and a possum or two, hoarders could have filmed an excellent episode in that room.
