How to Make a Huge House in Minecraft

Huge house #1

Make a huge base for the house ( 20 x 30 blocks). Mark this frame with a material of your choice.

Create the wall at about 10 blocks high. Do this for all walls of the house.

Cover the top of your house with a roof. There are two types of roofs: A flat one, just connect all the walls A pointed one. Put steps one step higher until both sides come together. Fill in remaining gaps.

Make doors for any gaps so mobs won't come in your house. Double doors are recommended as they look nicer but aren't necessary. If you are on hard difficulty it is highly recommended that you have iron doors so zombies don't break in your house. Build a bunker, just in case.

Place torches in your house for some light. If you have made a nether portal you can use glowstone.

Place torches outside your house to prevent aggressive mob spawning. Again you can use glowstone or jack-o-lanterns if you wish.

Create 2x2 holes in the front of your house. Fill the holes in with glass for windows. To make glass you must smelt sand in a furnace. Or, you could put no glass in them and snipe at far away mobs from the window.

Dig out the space on your floor and replace it with any nice block you would like. Brick and wool are two ideas, but hard to find, so pick whatever you find fancy. In creative mode, you have wool right on your fingertips, so take advantage of that.

Put a crafting table, large chest, 2 furnaces, and a bed. This will complete your house. If you want you can make chairs by putting steps and sign on either side of the step.

Huge house #2

Make a huge outline with 30 X 30 blocks.

Build the wall (using any block you want) 15 blocks high.

Make the roof. It looks best with stairs but it's your choice.

Make the floor. Use oak wood planks with wool carpets.

Put in double doors. This helps it to look better.

Add really big windows. Add a few small ones too, for variety.

Add as many floors as you want.

Decorate in any way you like. Keep expanding the house as you play.
