The construction of the tree house was carried out almost entirely onsite in Greece by three of Blue Forest's craftspeople. The team employed a special technique that allowed for the tree house's subframe erection without any fixings to the host tree. Unique to this project was the high site security required by the client. "Someone from the client's security detail remained with our craftsmen at every moment — even to the toilet or while waiting outside of the door to enter. My staff was required to hand in their passports, mobile phones and cameras to armed security personnel at the main entrance," says Payne. Despite being slightly amused by the extremely private nature of the client and the high security, Payne's team proceeded just as if they were building at home in the United Kingdom.
