Wasn't this a question last year? I would love the hi-tech room briefly described there, but I think the cosy room is the one I can better expand.
So: big, comfy, flumpfy sofas and cushions for the players; a comfy chair for the GM, with a table the right height for whatever tools they need. A ceiling fan. Blankets. So far, so combining my lounge with my friends' conservatory. Possibly why this appeals to me so much.

There's more, though, to move into the 'money no object' realm. Mostly, I want a huge library with floor to ceiling bookshelves, andthose cool library ladders that whizz along rails, and a spiral staircase to the game area, which would nested in a top corner of the library on a mezzanine overlooking the main library. And there would be at least one secret passage opened only by pulling on the correct fake book. Maybe that's where the hi-tech game room would be hidden...
