The current area that you can play on to put your buildings on for your base is 40 tiles by 40 tiles giving 1600 tiles to place things on. this is quite a bit of room, but I feel it would be nice to have that extra elbow room for your base allowing more different arrangement especially to move unimportant buildings a bit spread out as a distraction from the attacker to make the playable area be 45 by 45 tiles giving an extra 425 tiles or a roughly 25% larger area for your base.
