To reach those high and hard to reach places while building in Minecraft, you can use the classic method of climbing with piles of dirt blocks or building scaffolding. Scaffolding makes building in Minecraft much easier, so here's how to make and use it.

To craft Scaffolding in Minecraft, you will need six Bamboo and one String. Fill the first and last column of the crafting table with Bamboo and place the String in the top middle square. This will give you six Scaffoldings to use.

Strings fall from spiders and webs that spawn in multiple structures and caves. Bamboo grows in the jungle and you can plant it in the ground near your house to grow more when the jungle is too far away to go back.

Scaffolding works the same as ladders, except for the blocks. Place a scaffolding on the ground, stand in it, and spam the place button while facing the block to quickly build a tower. This is much faster than jumping and placing blocks below you. You can then go up and down the tower with the jump and crouch keys.
