If you are looking for ideas for creating pockets of spaces through partition, especially in a small space, i have a couple of suggestions here which you may consider. These are some of my research when I was planning my renovation too.
1.Using storage units as partition
This is a great way if you are looking for some 'porous' type of partition. It kinda kill two birds in one stone, allowing some visual separation while still functioning as storage unit. Pros of these are that the storage shelves can be access from both sides. Cons are these do not provide much visual and sound isolation
2.Pull across curtains
The simplest and probably the most elegant solution. Gets the job done with visual separation, and a bit of low volume noise. Pros are that pull a curtain is almost effortless.
3.Sliding doors as partition
This is the most expensive option among most. Pros is that it allows a confined space to be partition out. Useful if you have activities that requires good amount of isolation e.g. Music playing. Cons are these are usually the most costly option to install, and they remaining pretty much fixed.
These are the more common ones i came across, feel free to add on!
