Thanks for the comments. This is Wat Rong Khun temple in Northern Thailand (Chang Rai province)
From google:
"The temple has been designed and constructed by a famous Thai artist named Chaloemchai Khositphiphat. The construction of this contemporary temple is the artist’s lifework. Even though the temple has not been finished, its striking architecture has attracted many tourists who would like to see the great Buddhist arts. The ubosot of this temple is in pure white and adorned with exquisite traditional Thai style stuccowork, aiming to represent heaven"
