Earlier we looked at Danish company Dolle's in-ceiling storage system, deeming it ideal for tall people who live in small apartments with high ceilings.

That system's opposite is perhaps this Hong Kong apartment, designed by Sim-Plex Design Studio, with copious storage built into the floor. More precisely, the floor of the main room has essentially been lifted to meet the windows, which not only provides a feeling of floor-to-ceiling windows, but adds a lot of storage space underfoot via removable panels.

A table with a motorized lift has been incorporated near the window.

There's also a track in the floor to accommodate a room divider that unfurls from the wall.

The child's bedroom (here using the mother as the model, presumably for privacy reasons) also has a partially raised floor, which doubles as seating for the built-in desk.

The storage might not seem terribly convenient to access, but we should point out that this apartment is just 492 square feet and houses a couple, their son and occasionally the boy's grandmother. When you can't go up and you can't go out, going down is the only option.
