Replying to Ive got everything, i need ideas.

I want to build a summer setup which i can use in summer and when it snows. My garden is at a angle but not that steep at all so i will need a small drop in. I'd like to make a big wide drop in but which isnt impossible to move. As you can see due to my dad owning a construction company i've already got all the materials in his construction site next to my house...
