[mod request] building up higher/tree houses

[Blockster39]

if i could mod i would try this my self but i cant so you know.
i like the idea of building up higher because on my friends game we use the zombie apocalypse mod for alpha 6 and i think it would be good to have a house higher up so we don't die so much. if someone could make this mod i would be grateful. also i am buying the game very soon.
