Thank you, yes I can certainly understand the aesthetic appeal. For me being 185cm tall, my question was for practical reasons. I have found in many Thai built buildings, and indeed in my current rental, the drop floor in bathrooms means the top of the door frame is quite low, meaning I actually have to be careful so I don't bump my head...
Whilst my build will not have dropped floors in bathrooms, I do like the idea of taller than normal doors.
Cheers!
