Unity Level building

After finishing the first person camera i started building the basic layout of my stage, so the first thing i did was go to create and choose plane doing so created a flat plane to walk on this would be the starting area, i then created a platform going up and adjusted it using the rotate and scale tool, the shape i used to create the platform was a cube which i had scaled to create a path heading up towards another square platform, i repeated this creating a spiral going up towards a larger platform area in which it would end. 

When creating the stage for my level I first used objects mainly cubes to create the foundation and layout, to achieve this i first used rotation and right mouse button to clip parts of the stage together after using scale and rotate to position and alter the shape to my desire i finished the basic layout.
