Maybe make a larger area of granite in front of the house, and add a fountain and/or different houses?
You can separate the lobby from the map or if you want players to see/spectate the map you can add more rooms, NPCs, maybe shops etc. You can expand the lobby by adding these kind of stuff. I don’t know what you’re building, so i tried to think what could it be from the screenshot but that’s all i could think of.
I think this is a wonderful idea, no matter the game concept. Thanks!
