Building in Minecraft is hard.
"You can picture the house perfectly in your head.�But translating that vision into blocks,
one layer at a time, takes
hours."
Hours of counting blocks
Manually placing walls, roofs, and openings one at a time.
No visual planning tools
You build blind. No preview. Tear it down and restart.
Lost in translation
Your sketch never looks right when it becomes blocks.
