Maybe out of reach or extreme but here's what Gary Chang did to his 344 sq ft home in Hong Kong.



The steel tracks I can think of is available from Raumplus but not sure if Mr Chang sourced for the same as the load imposed could be higher.

Tree Hugger's Graham Hill 1100 sq ft in 420 sq ft.


The design of such nowadays earned it appropriately the moniker transformer apartments.

Your bathroom at 2170x2020mm is modestly large but there's only one.

If you are renovating the bathroom and open to this radical idea, here's a tip from having lived in apartments over half my life. If it is possible to do what the Japanese would do: carve it out in such a way that 3 individuals can use it at the same time. It seems possible to carve this unit's bathroom into three separate rooms: toilet, powder area and shower room.

But only if additional floor traps are readily present at these areas:
i) next to WC
ii) near sink
iii) shower area already has a floor trap so that's a given.

If i) and ii) are there, you can then do this.

I know that this is a studio for a single person but if you have guests over or even for married couples young or old with no children, it would be practical. I think the value of your place can command a higher price than the neighbouring ones of the same layout but did not do the same for the bathroom.
