Minecraft.
I love my house. It's built in the side of a hill with two glass patios, a fireplace, and an art hall.
Soon to add;
An "Nature Dome", built behind the fireplace. You get to it by the passage behind the fire place.
A... secret room behind a painting... will hold furnaces, storage boxes and a crafting table.
A church like room with a cross made out of cobblestone on the wall with water flowing around it.
