Lit only by dim blue lights and furniture recessed into the walls. Under each seat there would be independant subs that have an adjustment knob so one could adjust the bass response to their pleasure. On the opposite walls would be 6 pc's all configured for gaming and LAN's. Hanging from the ceiling there would be a hookah with 10 hoses that has some lights in it that flicker to the beat of any given song. Built into another wall and continuing into the floor(so it is like pieces of the floor are the fish tank and you could walk on them, but the only visible spaces would be in the pattern of all the continents) would be a 1000 gal fish tank that is sectioned off so different groupings of fish could live within it. The roof and ceiling would be glass with a cover on it that is automated so that at the press of a button on a beautiful day we could have the sky to look at. And all around the room would be mids and tweeters distributed to give the best sound quality available. On the areas of the walls that aren't covered with some built-in feature, I would have it setup so friends and myself can paint on them, and quotes written all over the place. The areas of the floor that could be carpeted, would be carpeted with a suede material.

Oh and a refrigerator built into the center of the couches that are in the walls, so drinks and food could be easily accessed.
