I do indeed

I'm a dude but I really want one of those.

Why don't modern homes have these? I'd never leave my house

This isn't a cave, it's an alcove.

I still want one, but have already accepted I'd never be allowed to use it because of cats.

There is a part about these in Christophe Alexander's "A Pattern Language: Towns, Buildings, Construction ". Worth a read.

Oh fuck yes i yearn for this. That looks cosy as fuck

Wait then what was a "mancave"? This looks hella nice

I could see building one of these.

Put two closets on a wall. Space between should be a standard twin bed size. Built in bedframe (with good air flow) and drawers beneath it like a platform or day bed.

Tasteful curtains to close it. Seems like a baby canopy bed.
