this was the first patio I have ever built. I always wanted to do a patio in this area but figured it would cost more than I was willing to spend. So I decided to experiment with making the bricks myself. to my surprised they turned out great. the biggest expense was time. a bag of concrete made almost thirty bricks for under fifteen bucks. three trailer full of pre mix sand and stone cost ten bucks a load. I poured all the bricks last summer and fall and set them down this spring. Approximately 500 bricks in total.
