New Walls and Floor

I have one wall made so far, this has one window. I can use this as a template to making the rest of the walls.
What I have so far is a floor with 2 layers that can be raised and lowered into the floor. I show the wooden floor and one layer has the rug and it is higher than the water puddles. This makes it easy to show a rug, or anything you want on the floor with a layer of water for a wet floor, so you can use it to show a fire with burnt ashes on the floor soaked with water, or anything you can imagine. You just use the layers to make your own ideas.

The wall is wall 1 like my other walls you can put together to build a house or rooms. I will need to add a 4x4 for the corners and trim for the outside corners. The walls has the 2x4 frame, insulation, dry wall, wall paper, and the outside has the outer wall, and the siding. You can make these all transparent and show the house under construction. The walls are 12 feet long and has the ability to do more than show color, because they needed to show a whole in the wall. You just make everything transparent and you have a new doorway for a door anywhere you want it. The only thing to remember is the 2x4's are hollow. This means you can put in an entry way door with side windows in any wall. You just use a image on all sections through the 2x4, insulation, wall paper, siding. Just one image to make the hole and add a door or window.
This wall was made with the window, before I thought of this, and wall 2 is a solid wall, so it will have that ability.
I wanted you to see what is in the wall in this render. I think all you will need is a 4x4 a 2x4 outside trim, and if you could see the bottom of the wall paper I built in a base board. The floor has a ceiling on the bottom, but I didn't add the inside like the walls.
The best purpose of this is to limit what you need to build anything, and show a house under construction that might need plumbing showing.
If I get everything done you can use building plans to build a 3D model of a house, that can be made in real life.
I have other things in mind for the future, but it is too soon to give away my ideas, but this, I have.

I will say the furniture will include this end table and lamp that can add lighting to a room as you see it here in Daz Studio renders
