We just had 700 sq. ft installed at a cost to us of $2500. This included drainage and framing. We are in So California. Depending on where you live, the cost could be less or more. We got 5 bids. We didn't take the cheapest one. We took the bid that included some suggestions that we hadn't thought about.

The only suggestion I would make is not to make your patio too small. It needs to be large enough to accomodate guests with ample seating far enough from the BBQ so they don't get smoke in their eyes. Make sure it drains away from the house, and if there is a drain pipe from your gutter be sure to dig and connect a drain under that so water doesn't pool on your patio.

Have fun!

Desertdance could you please explain the prep procedure? The contractor we initially selected stated there was no need to remove the grass. He said he pours the concrete over the grass. That goes against everything I know from reading articles and watching hgtv and diy for the past decade plus.

Well, I'm no contractor, but I'd get more bids and see what others say. We didn't have grass where we poured, but they did dig out a lot of soil, dumped it in a spot where we need some height, and rolled the area flat. They also used levels to be sure the frame was draining away from the house.

Good luck!
