This is what we have that I rather enjoy. Half a dozen programmers in a room with cubicles, just have to lean over to talk to somebody (teams are next to each other).

Further discussions are moved to the conference room which is dedicated to us programmers, with a TV we can cast to, etc.

Off topic discusssions or lengthy ones are expected to take place in the conference or break room.

We have ms teams (bleh) for trivial questions.
