Hi,
First of all, I wish You a good health during this crisis,
Since You asked for everything inside this compact space, I have designed You a Living room/kitchen , bedroom and a bathroom in a minimal style and taking into account that the space is considerably compact , I have reduced the sizes of certain things such as cupboard in bedroom , which You can see in the bedroom render is just behind the TV, (acts as both a TV stand and a cupboard).
So hope You like the designs.
Thanks in advance,
Kindest Regards.
