First of all this is my first instructable!! so excited and nervous,
My and I had a number of friends on our Minecraft server who kept stealing our things so we decided to create a secret underground treasure room with a secret lever to stop people from finding it! it worked well the server carried on running 24 hours and we kept our things :D
Step 1: Time to Start the Build, 1 Block Deep by 5 Blocks Long
We first of all dug 1 block deep x 5 blocks long, then missed a row of blocks to the right and then dug 1 block deep by 5 blocks long x2.
Step 2: Sticky Pistons
Add your choice of stairs, do the usual digging diagonally down and adding the stair blocks so it goes deeper the more you go down the stairs.
Where the Dirt block of 5 was replace it with your choice of flooring and next to that 5 x sticky pistons facing towards your newly lay floor.
Behind the sticky pistons Dig another 1 block deeper so will be 2 blocks deep in total
Step 3: Redstone Repeaters
Next to the pistons add 5 x redstone repeaters (set the top step repeater to number 4)
next to the repeaters dig 2 blocks down by 5 long and add red stone.
Step 4: More Digging!!
This is very hard to describe!!
I've tried my best in the picture to capture the depth and length / width required for this part of the process.reds
Step 5: Redstone Time
Follow the redstone trail and add 2 further repeaters, note the repeater behind the Wooden planks is set to 3, have a redstone torch set on the other side of the wooden planks, also a redstone torch on the lone piece of dirt at the top of the left hand rectangle.
Step 6: STICKY PISTON TIME!!!!
Place x 2 sticky pistons in the appropriate places, they should automatically be extended as they are activated by the red stone torches. (second picture i deleted the wooden stairs for the picture so you could see orientation of the piston)
Step 7: Build the House Around It!
next its time to build the house around the stairs. i suggest using the lever to switch the floor closed so it is easier to see where needs to be covered.
Cover the piston arms with either bricks depending on how your building will look or in mine we used crafting table, juke box and oven (chests do not cover piston arms completely!)
Then where the switch was placed we left a x 1 deep by x 2 high hole placed signs on the inside of the hole.
Then Cover the hole with a nice painting if you click the bottom left block next to the hole if will give a variety of paintings and one that is 2x2 would cover the hole.
When you use the lever and open the floor to revel the stairs go down and enjoy digging yourself a treasure room!!
