It's bigger than it looks, and takes up the better part of a 1000x1000 block area.

I've seen a lot of other White House builds that were claimed to be 1:1 scale, but few, if any, even came close. The people on my channel wanted to see the White House so I created what I believe to be Minecraft's most accurate White House. I used pictures of people standing next to the White House in order to scale things accurately, and I used whitehousemuseum.org for blueprints and interior pictures. The only floors I did not recreate were sub-basements containing laundry rooms and electrical contraptions and such. Google Maps was used to place trees in the proper locations.

In modeling each room, I made sure to keep color schemes the same, including walls and rugs. If it was possible to recreate the floor pattern or rug in a room, I attempted to. If not, I created similar patterns using all the same colors. If there were no pictures or even a description of what a certain room was, I was forced to leave it alone (because I wanted the most accurate White House).

All 132 rooms of the White House were incorporated into my build. As a bonus, I also added a perimeter alarm with redstone leading to the Ground Floor Secret Service Office. There, four alarms tell you the direction (N,S,E,W) that a potential security breach is coming from (via tripwire). All of the redstone concerning the alarm is encased in bedrock. I also created a secret underground bunker in place of the White House subbasement, which contains an Emergency Operations Center and is also encased in five layers of bedrock.

The bunker has a functional 7-digit combination lock. An actual redstone button lock, not one of those "hey I can press the last few digits and it opens" things. The Youtube video shows it in action.

Anyway, I know there's some hardcore projects here that'll outshine this by a lot, but please let me know what you think. You'll probably get a better idea of the scale if you watch my Youtube video. If possible, I'd love posted feedback on the video itself.
