Hey, I want to split up my garage by basically just putting a wall in the middle. it's all brick with a corrugated iron roof and a bluestone floor. the garage has no door it is completely open to the backyard, what I want to do is nothing special and I could easily do it but the floor has an incline as you get further to the rear of the garage, the back area of the garage must have a flat floor as I will be doing some delicate work in there. All i want is an idea of how i can build this wall and flat floor as cheaply as possible.
thanks..
