Started the map on minecraft 1.5.2 just to build a single house but have been adding stuff to it ever since to test some stuff.
Optimized for 1.7.10 can be used in 1.8 witch is better the command blocks that use the fill command work. Can be used in 1.6 maybe earlier. But the command blocks mite do nothing.(just remove all the maps in item frames from the world first they like to crashing the game)
Has command blocks everywhere to teleport you around to the different areas.
Has redstone creations from a few people I've seen like the useless machine made by sethbling(sorry but i don't remember who made most of them)
The main house has the teleports for most areas (every one is labeled). In the basement there is a room for toggling the gamerules and you'r gamemode. Another room has command blocks for giving items and potion effects. Behind a 2x2 jeb door a hopper clock for commands like keeping the weather clear(add or remove a repeater to chose witch blocks will be activated). and 3 1000 block long railroad track(goes to the original spawn area).
The shed next to it has command blocks to give you levels, change gamemode, and replace the anvil to test enchanting with an anvil.
The chests have all the tools and items made unbreakable, some enchanted books, and some common item for crafting.
More stuff around, the buttons will take you to them.
Mod Support Areas
Have an area set up for the thaumcraft/blood magic mods and tinkers construct(also has areas for testing weapons and tools.).
for blood magic there is a structure set up for a tier 6 alter(just needs runes and alter the wools and lapis mark out good spots for the different type of runes will label what each means later). Has a small alter I have found good to collect life essence(same as the big one needs runes and has blocks to mark what to put there).
For thaumcraft have a place for an infusing alter (area below it to fill with stuff to lower the chance of something bad happening) and every vanilla block in a row to scan.
For tinker construct have a layout for 2 smelteries(if made right 1 will make steel and gold the other will make pig iron) and chests full of all the stuff used for modifiers and stuff to make the stuff to make items used for modifiers.
There is more than what I put above and I'll keep adding more to it over time.
I will take suggestions for stuff to add.(mite need to make a new house at some point)
