Grey sandstone looks superb. I prefer the random coursed to the four flag random. I see that you have utilised the small square within the course. Never seen that done before, looks good though.
Second patio looks top job as well. Not a cross road in site, as it should be. Haunch looks good too, thats not moving anywhere.
Stone on the second photo looks the dogs. Really flat with barely any riven. Where is it from?
