I started off by creating a small house structure in the program called 3-D Max, I made 2 walls first one length wall and one witdh wall. Then I added the windows to do that I made a box go 2 boxes go through the longer wall, then selected the wall where I wanted the windows and selected the compound objects menu. Next by clicking on pick Operand B then just clicking on the boxes going through the wall, which deleted them making holes in the wall.
Then I went about copying the 2 walls by going to the "select and move" button and then selecting one wall at a time holding the Shift key and then draging the wall out to make a duplicate of it. After I had all 4 walls Imade a floor by making a flat surface and then re-sizeing it to fit the house. Here is a screenprint of the house
