Solution

This is a spinoff from my main idea, The real Thing, from trying to decide how I could come up with a layout to suit someone who's personal preferences are essentially unknown. 

Not only can absolutely everything except the recycled water tank  be stowed on the ceiling, but everything including the kitchen and bathroom has wheels and can be rearranged to anywhere, and in almost anywhere, as long as the orientation is aligned, it can still be raised to the ceiling, because the width of the storage boxes and bathroom etc. allows them to be raised and lowered all by the same mechanisms.  Water connections use RV quick connectors, with 6 possible connection points in the ceiling, embedded in the ceiling above the boxes, and appropriate drain pumps.

Raising and lowering is done electrically, with 24 separate actuators in the ceiling.  The sides of the boxes can be folded down, and they can be connected together to form a box that is twice as long, or connected together to form a tri- or even quad- size box.

Importantly this would also includes the main features of my previous design like attention to acoustic details, energy efficiency, fair sized bathroom, ease of obtaining acoustic and visual privacy from others in the apt., useable kitchen, etc. The ceiling is lowered in the drawings by 4 inches to show this, because the sound proofing and acoustics will take about 4 inches of headspace.    Not all the requirements are incorporated into the drawing due to time contraints, but you can see there is room for them.  Well, the tool box might be better staying on the floor. 

The boxes would be arranged in a more regular way, but I couldn't get things quite in the right place with sketchup.

There is a total of about 300 cu ft of storage, including what is in the office and bedroom.

The boxes are about 3' 8" each.  The cables can be detached if desired from the objects with quick connects to eliminate the cables when the sofa, desk, kitchen etc. are lowered.   The ceiling is staggered stud construction, making it just as strong as the floor above so it can support the weight without compromising on soundproofing.  The boxes can have any of their sides folded over,  as shown, then they can be connected together to form a box with 2 or 4 boxes, allowing the storage of long objects like skis, the bicycle near the door etc.  Everything can be retracted into the ceiling, except for the water recycling storage tank. Taking advantage of the high ceiling obviously has problems for replicability, where in another apartment the ceiling would be lower.  But then taking full advantage of the particular situation will always have that problem.

In between each box there is 1.5 inches for an acoustic curtain made wi8th recycled rubber from Audimute to travel along a grid of curtain tracks in the ceiling, allowing it to be pulled to almost anywhere in the apartment. 

The bedroom has 2 extra winches and a structural frame above it, which are removed from the ceiling and relocated when the bedroom is moved, used to raise the walls easily. The bed can have legs that could fold down, or it can remain suspended at a certain height from the ceiling by the cables.  Cables are all dyneema rope or shark fishing line for lasting durability.

The kitchen has flip up panels by it's side which can form more counter space and table space , and a rise-from-countertop shelving unit with adjustable spring force to aid pulling it up and pushing it back in, because being 3' 9" deep there would otherwise be wasted space at the back.

The connections for water to the kitchen and bathroom use the same sort of quick connect connectors used for RV water supply and drainage, as well as as drain pumps, including for the toilet.

 The water system is done differently, using a 6 liter hot water tank and powerful heater element and ecodrain heat exchanger to reduce the weight of the system so it can be integrated with the bathroom and kitchen but still be raised and lowered easily.

The actuator winches for the ceiling would need to be worked out, basically just a geared motor and a few limit switches, maybe with some measures to prevent overcurrent or overtorque conditions and a pressure plate above each box that stops the winch when pressed.  Each box has 4 cables, on for each corner. The winch winds in all 4 in parallel.  Ideally everything would be controlled with a programmable logic controller.
