A poem divided into stanzas is a house of rooms. It's not a great hall with space not formally separated by walls and doors.

Then it might seem odd that I chose the poem "A Story" by Philip Levine
Levine is writing about how a story can be a house, a series of rooms, filled with things -
"tables, chairs, cupboards, drawersFor this month's writing prompt, our subject is a room or rooms. The form is any number of stanzas, but we ask you to think carefully about how you arrange those stanzas. Should 4 rooms be 4 stanzas? Should the movement from room to room be done only by stanza breaks? If a poem about one room has 4 stanzas, why is that?
closed to hide tiny beds where children once slept
or big drawers that yawn open to reveal
precisely folded garments washed half to death"
When you use a poetic form, the rooms are affceted. In ottava rima or rhyme-royal, the rooms all have the same size and shape. Very tidy rooms that rhyme nicely with each other.
Two lines is a couplet. 3 lines, a tercet, 4 lines, a quatrain and so on... Does size have something to say about the size of the rooms - or does it indicate...
Let me be a formalist here and say that style and meaning are inextricably connected.
What kind of building would have the rooms of a sestina?
