Unlimit

Unlimit is a simple datapack that dramatically expands building possibilities in Minecraft by increasing the maximum construction height by over 700 blocks. Now you can build structures up to level y=1024!

This is the perfect solution for builders and players dreaming of creating impressive sky bases and high-altitude constructions. Unlike many similar modifications, this datapack doesn't cause TPS (ticks per second) drops and uses world generation mechanisms instead of shulkers, ensuring stable performance even on servers.

An additional advantage is that Unlimit automatically updates the "Caves & Cliffs" and "Star Trader" achievements, adapting them to the new world height.
