At the moment, There are only two types of buildings in this mod.
The first being a normal home with a cobblestone roof and wooden plank floor, It has 2 Furnaces aswell as a DayZ chest and crafting bench.
The second building is a tower , which is made of only stonebrick and stonebrick slabs. At the top it has a chest and torches.
For more information you can use the individual pages.
A generator bug means that sometimes furnaces may be facing the wrong way. There isn't any known fix.
