A Room Within a Room That People Can Stand On

I want to draw a “room inside a room” in Home Sweet Home 3D. Here’s the idea:

A 16’ tall wall at the back.
An 8’ x 8’ “box” placed against the back wall.
Stairs on either side of the box leading up to a floor that people can stand on.
A railing along the stairs that crosses over the box for safety.
A door into the box below—the box is a room inside the larger room.

I’ve already drawn the walls, but I’m having trouble creating a ceiling inside the box that can also serve as a floor on top of the box. Is that possible in Home Sweet Home 3D?

Note: In Home Sweet Home 3D, the ceiling of a room doesn’t automatically become a floor for another room. A common solution is to place a separate object (like a box or platform) to act as the floor on top of the box.

Replace the 8x8 box with normal walls and the height you want.
Add a level with the elevation set to the height of the box walls + the floor thickness of the new level. On this new level draw a room using the outside corners of the box walls. Magnetism will help to snap to the wall corners.

Now you have a floor and inside the box you have a ceiling.

Notice that the floor on the new level "sinks" into the lower level with the floor thickness you have set for the new level. That also sets the ceiling height inside the box. You can lower the ceiling by increasing the floor thickness of the new level. A thicker floor will "sink" lower. You will have to lower the box walls too.
