CHECK OUT MY MANSION!
I built this mansion on my Singplayer mode. It is 5 storeys tall (3 above ground and 2 below)
It is around 20x20 blocks wide and probably 30 blocks tall (if you include the underground floors). It has a balcony at the front above the doorway and a staircase is used to go from floor to floor.
You cant really see it but theres a spa on the roof.
It has around 80 rooms (16 rooms each level), each room has a bed and several blocks of furniture. Paintings and torches suround the corridor.
The mansions backyard consists of a wolf kennel which has 9 wolves in it, a football field, a nether portal, a pool and a really long minecart rail.
ENJOY THE PHOTO!
