Making the house

I started out with a cube, and cloned/scaled it to make a smaller version. I used to boolean tool hollow it out. I created a prism to use as the roof, and made a door with the boolean tool. I also made a doorstep with a cube.

To make some windows, I created a large cube, and four smaller cubes. I placed these to create the shape of the window, then cloned all of them to the other side of the house. In order to to through to the inside, I used the proboolean tool to union and subtract the different pieces.

I finished off by adding in a floor, and creating a glass material to add to a plane. This I placed inside the wall across the front section, so it is only visible in the windows.
