Meta: I considered asking this on WritersSE, but I am less familiar with it. I would not object to a migration.
Problem: I want to edit the following sentence so that it is as brief and aesthetically pleasing as possible. I specifically want to change the italicized part.
My home is a place where I (i) enjoy being, (ii) can work and rest effectively, (iii) can escape from the world to be alone, and (iv) can spend several days without going stir-crazy.
I have made the description long for the benefit of this question. I don't want to have a list like that. A word or short phrase to describe my home would be ideal. Feel free to alter the structure in any way. The revised sentence needn't perfectly capture all of the above qualities but should bring to mind their core concepts.
Non-solutions: Here are some options that I have found and rejected after checking some thesauri and similar threads on this site.
Words that are close but not right (in somewhat descending order): shelter, refuge, sanctuary, retreat, sanctum, harborage, respite.
The problem with some of these is that they suggest that I am in serious danger outside of them, which is not what I want. Some are not especially enjoyable or long-term. I'd also like to avoid religious or spiritual undertones. I would consider using these words if these problems could be largely avoided.
Words that are definite rejects: lair, den, roost, manor, demesne.
These are mostly getting more specific than home in an irrelevant way. The meaning of roost is not terribly wrong, but I do not want to compare myself to a chicken or other animal. I also want to avoid being obscure or highly metaphorical.
My best current idea is something like:
My home is truly/thoroughly/?? my shelter.
My home can completely shelter me.
These are missing the idea that I am happy and productive there. I also want to avoid the implication that I am sheltered in a negative way.
My home shelters and nourishes me.
This is very close but could use improvement. Very different options are of course welcome.
