Therapist moving offices: Thoughts to honor old space and welcome new one?

The T I've been with for 6 years is moving his office in a couple months. It's not that far away, and will actually be slightly closer for me. But I'm pretty attached to his current space. And he's said his new one will be "75% smaller," too (his current one is quite large).

I struggled when ex-T and ex-MC changed offices (even though it was literally up the block). I'm thinking it might help to honor/say good-bye to the old space, including the work we did there, and welcome the new one. I'm trying to figure out what might feel meaningful that my T would also agree to.

Ideas? I know another therapist in his office suite burns candles, so I assume they're allowed. So that's a thought, something involving a candle (for good-bye and/or welcome, depending on rules in new building), but I'm not sure what specifically to do.

And he has a small glass fish in his office that I gifted him for the 5-year thera-versary, I wondered about asking if I could be the one to place it in the new office. But I don't know what he'd say to that. (If I hadn't already given him something for his office, I'd have considered that, but not trying to add another thing, particularly with it being smaller.)

Any other thoughts? Is there something you did--whether with a therapist, when leaving an old home/moving into a new one, etc. that you found to be meaningful? (I feel like this has been discussed before, but it seems like a difficult topic to search. Feel free to link if you know of a thread.)
