Hi Mosi,
Wow, what a beautiful space! i'm not sure exactly what pavers were used as the color is hard to determine in the photo, but they've got several different sizes going on to create that gorgeous pattern and edging. You might want to check out our country cobble pavers .They are similar in style and come in a lot of different colors. We have brochures on our website that you can check out, too, with other styles you might consider. www.basalite.com
Feel free to email me if you want more info. Good luck with your project!
