Introduction: How to Build a Modular Lego Wall for Your Modular Building
I discovered a way to incorporate "striped" wall paper, not only that, but it can be switched with other walls in your building! Now, if you get bored with a room, rather than having to rebuild the whole room, you can constantly upgrade your existing modular buildings with new colors and patterns!
Step 1: Choose Wall Color/Build Wall
Choose your wall color!
The awesome thing about this wall is that you can literally constantly upgrade it! As Lego releases new colors regularly it makes it easier as a fan to incorporate them into your existing models.
The main part of the wall - the "striped wall paper" is made up of 1 tile, 12 bricks, and 13 plates. Alternately - if you wanted one single color, no striping, you could use 16 bricks, 1 plate, and 1 tile since 3 plates = 1 brick. Using the same math, I think, the cooler thing is that you could also build this with 49 plates for a 'tighter' or more alternated striped design - possibilities are endless!
For this instructable example, I built the base of the wall three bricks high, The 4th layer is two layers of plates, the top layer is 20 studs wide of tiles - see photos for better details. The support of the walls are 5 bricks high. Separately, I then built the vertical "wall paper" with 1x6 bricks and 1x6 plates. This is a SNOT technique (Studs Not On Top). The wall itself is 23 studs wide and the wall paper takes up 20 studs of it. Please reference photos.
Step 2: Put the Walls in and Flip-Flop
Once you've framed out your walls, changing the walls is as simple as 1, 2, 3...
To remove, gently tap, or push the wall out towards the back of your building, as it comes free from the front of your model, continue the "peeling" motion and the wall will come off - you may get a plate stuck every now and again, but it sure beats rebuiling a whole wall. :)
To reinstall the wall, line the "bottom" of the plates with the studs at the corner of the building, push the plate down like normal. After the plate is fitted, line up the wall and align it with the rest of the wall - it will slide into place and hold itself by pressure alone. Have fun experimenting with other colors - the other lengths are possible too; try using 1x8 bricks and plates or 1x10 bricks and plates - have fun!
