Think hard on your plans and materials. Draw and sketch. Make notes. Think of alternatives. There are many ways to do the same thing. I had a couple of years to think about the best way to tackle this but it was a good delay, because I may have settled for something inferior. Use information gleaned from multiple sources and get acquainted with improvisation, adaptation and the ability to overcome problems. The abundance of information here may be daunting at first, but take a look at the pictures and all will become clear! Make sure to view the video presentation above.

Make sure you check with your local council or land planning authority before you start building. Initially, I was told that I could not build  in front of my house AT ALL! I was going to move it around the back. If I kept it under 3 meters in height above natural ground level, under 25 square meters floor plan and not painted white or off-white, then  it's a class-10 building and I wouldn't need building approval.

However.... I rang them again and got a different person and a different answer. So then I went to see them. (always better in-person if you can) As it turned out, I was able to proceed in the front, provided I fill in a few forms and seek approval. Best advice... be patient and check again!
