Khun Sea,

Looks good even under the rain clouds. I do believe you need to put gutters at least around the front. When the rain came down there was a lot of water coming off that big roof and flooding the area and anyone trying to walk around. I know its early yet so I'm sure you have plans for that before the final finishing touches.
We were there just before lunch and it appears the workman added the steel on the wall just after we left. I saw them drilling up top but missed the install. Will the steel remain black? Or get some different color?

The driveway tile is really nice and seems not too slippery in the water. Good choice as is the patio stuff.
