Village Expansion

Clash of Clans is only going to grow and with growing town halls and more and more building and walls, we are going to run out of room. So I propose the idea to expand in any direction. You could expand (by the same size as the village is to begin with) into the forest or maybe even out over the water on a dock like structure. Hmm, then they'd have to include a sort of aquatic attack, like troops swimming up to the dock, they'd be safe from defences in the water, as they wouldn't be able to fight back. In the winter the water could freeze over and would change the entire dynamic of an aquatic raid.
