The second floor of the structure will not have any details in it. To make the second floor "float" above the first floor, I decided to connect it to the roof panel.

Also, after experimenting with the internal lighting of the first floor, I decided to the build a raised ceiling section so as to move the lights further away from the details on the first floor. This is because the farther away the light source is from the target, the wider its dispersion.

The interior lighting of the first floor is accomplished by three 5mm bright-white LEDs in series with each other and a 1000-ohm resistor (the power source will be a 12-volt supply line). The bluish tint of the LEDs will represent fluorescent lights in the building.

The center block on the second floor styrene is the raised ceiling section wherein the lights will reside.

If you were inside the building standing on the first floor (where the details are) and look up, the photo on the right here is what you would see. You are looking at the ceiling of the first floor. It has been painted with Floquil's "Rail Brown".

My particular bottle of this paint is going bad, and so after applying one coat of this paint, the styrene's surface made the paint crack and dry up this way. I like the look; aged, flaky paint.

The LEDs have been installed (glued with 5-minute epoxy), and a toothpick has been superglued in place to make sure the LEDs are pointing straight down.

The other side of the styrene sheet (the second floor) and the underside of the roof panel were also painted "Rail Brown", and the roof top was painted with Poly Scale's "Steam Engine Black" (to represent tar).

The whole second floor/roof assembly is shown here, ready for installation.
