We are going to build the floor for the diorama building, take the measurements, length & width. The building I made ends up being 20’ 6” x 12’ 6” in real size or 10 ¼” x 6 ¼” (1:24) scale. You could just trace around the sides of your building make sure it is square.
The framed structure/studded walls are actually 20’ x 12’ in real size or 10” x 6” in (1:24) scale. Remember the hardboard is 1/16” thick so that adds ¼” to the overall size or 6”s in real size. This is where your scale ruler comes in handy some people refer to everything in their scale where others refer to everything in the real building sizes.
I used a piece of 1/16” hardboard for the floor the same stuff I used on the walls but in a lighter shade so you could see the different. You can use whatever you want depending what you want your floor to look like, you could use the hardboard like I did and leave it to look like a wooden floor I actually covered mine which you will see in the future.
The edges necessarily do not have to come right to the edge because we are going to make it look like it has a concrete floor or base & when you look at a real building the base usually sits back just a little from the outside finished walls.
I find that if you turn the building upside door & put the glue on the bottom edges of the building & sill plate then set the floor on in works easier & you can make sure it is square easier this way. Turn the building over & let the weight of the building sit on the floor while the glue dries.
I wanted my finished floor to look like concrete I used a flat light gray paint & painted all around the outside edges of the floor so it looks like the building is sitting on a poured concrete foundation. The floor on the inside I actually used scrapbook paper it is acid free & will last for years compared to regular paper. Make sure if you are using scrapbook paper that you use acid free glue or acid free glue sticks to attach it and make sure you spread it out evenly.
I used a regular piece of paper & cut out the floor pattern around the doorways etc. to make sure it fits properly & then used that pattern to transfer it to the scrapbook paper & cut it out. This gave the floor a nice finished look & the scrapbook paper is not shiny & has a pattern so it looks pretty good for less than 50¢.
