Back when we were first testing out 512x64x512 maps, we sent one to The Largest Dog to try out, he pretty quickly made a map called "The Largest House".
The map resembles one of TLDs most well known maps "House of Madness", but it is completely empty other than TLDs famous Spacedog that he built.
Starting soon this map will be hosted publicly and everyone is allowed to build on it, to make things more manageable the map has been split into 4 256x256 sections and has had the other sections blocked off until the current section is completed.
The map will continue to be hosted each day for a week or until it is filled for 5 hours a day (how long game nights last).
