I've gotten tired of people asking what they should build. There's a new one almost everyday.
So I've made this huge list of things you can build when you don't know what to build! (List does not include redstone stuff)
EDIT: This is a list of architectural things to build for fun, not actual stuff that has use. Sorry!
Public Swimming Pool
An ENTIRE CITY
Invereted City (upside-down)
Blow up the city and make it apocalyptic.
Statue of your skin
Statue of yourself, IRL.
Legitimate statue of a real thing (like statue of liberty)
Airplane(s), big or small
Stadium (football, baseball, spleef)
Pixel art of 8-bit games
Pixel art of other stuff
Greek/Roman Building (pillars and stuff)
Chinese/Asian Building (dojos and stuff)
Fireworks in mid-air
Your actual House/Apartment
Underwater city (NOT Rapture, its been done)
Sky city (Columbia-the Bioshock Infinite city.?)
Regular Army Base, HUGE
Pyramid (lame-ass, no offence)
A real looking cactus with cactus blocks
Do the cactus on Normal Difficulty and no armor or flying....
A 2d Face
A 3D face
Realistic space ship
Fictional space ship
Well thats all I can think of at the moment, reply on with more suggestions (no redstone)!
Also, show pics if you attempted to build any of these things!
Yo will never be bored in Minecraft and not know what to build ever again!!
