I have been wondering what the size limitation of residences are. i know its normally 60x60, but i don't know if i can build all the way to the sky. I want to build a version of the space needle augmented by my imagination, but i want it to be huge but i don't know about any vertical limits and i currently don't have the means to find the max height. Thanks for any info and your welcome to anyone who this has helped.
The max height on the Empire Servers is 64 (Layer 127) blocks above sea level (Layer 63) Just like in Normal MC.
So from the bottom of your lot (bedrock below all the dirt) to the top is 127 so the total lot size is 60X60X127
I beleive the OP wants to know if he is 'allowed' - the answer is yes.... I would just ask that if super high make it nice to look at :0 Have fun building.
