VR Stage 3: Boolean Windows & Doors

To insert spaces for the windows and doors I started off by creating 3D boxes that were slightly bigger in depth than the walls. I then positioned them all on the model using the drwings as a guide to where the windows and doors are. Before I applied the bollean tool I added segments to all the walls. This made sure the structure was stable as when meshes are edited too much the model would collapse. Below is a screenshot of what the model looked like after the boolean tool had been applied.
