What started as a new road design that I have wanted to do for some time, has turned into a bit more than just a new road surface. I found that the texture the 1x3 slopes give off when switching the directions of the bricks creates a cobblestone or brick look. I am working only with dark red and black 1x3 slopes at this time and I have been limited on what I would like to do.
As a road surface, the bricks need not be attached from one strip to the other like my tile-only road surface which I will talk about another time. Basically you will have strips of 1x3 slopes lying next to other strips going the opposite direction. I have placed tiles on the Baseplates, with the surface of the adjoining display needs to be BP + 2 bricks high. Once I worked these out, I wanted to attach the sections to each other. In doing so, I have created a new roof surface.
Basically I have woven like modules together like you would weave fabric for clothes. For every section of roof that is attached to the building like a normal roof, you have an exact copy but flipped around that weaves thoughtout the fixed first module. Once the second module is in place, I can add the 1x plate to lock in the 2nd module with in the 1st module. This 2nd module has some play in it, but once it is all together, the unit is surprisingly sturdy, or at least until you drop it. With calm hands you can correct any parts that may start to come apart with a little effort. You just need to pay attention that you are pressing the correct bricks from the underside and top to correct any problems that arise.
Later I will talk about the roof design using 1x2 slope bricks. A little more fragile but I like the look.
