Dear k.wattanapon,
Please see the picture in attachment.
I think it s cheaper to keep the size of the terrase , 2m x 13m but on the left side front of the bedroom 14sqm, add on the terrase 3 meter and the roof can be like on the picture for the terrase so we can offerd to the Customer a place for eat or relax outside. We can use the same idea about the terrase for my house at the second floor.
the private swimming pool can be between this terrase with this roof until the entry on the right side like on the picture as well.
What do you think about this? I need advise from you to keep a low budjet but give a nice villa.
Thank you , have good day
Best regard
