My apartment in Brooklyn had 11' ceilings and I was able to do shelves much like TTK's setup. All custom birch ply shelving, floor to ceiling.
Now as I'm in the Hudson Valley and living in a house, the LPs are in a couple of rooms to spread out the load and not put undue stress on the floors. It's not as impressive at first glance (and I'm still working on the feng shui) but the contents are what matters. It's a modest size collection of about 6,000 LPs and 2,500 CDs.
