This mod adds in one main type of block which is scaffolding. There are two types of scaffolding(maybe more to come), wooden scaffolding and iron scaffolding. The wooden scaffolding can be placed almost everywhere except in the air, if it is placed in the air it will fall to the ground. The iron scaffolding can be placed absolutely everywhere, even in the air. The scaffoldings can be used in place of a ladder and they do not need a block behind them to be placed or used.
