My treehouse in a barrio in Bugallon, Pangasinan was constructed in 2004. I have an architect who help design it and trained the local carpenters how to execute things -- my friend and former Narra dormmate in UP Diliman, Clifford Espinosa.
Since the house is perched on a big and live mahogany tree, construction started from the top, the trusses of the roof of the second floor. Then the 2nd floor was built, then the 1st floor. Bottom right photo is Clifford with another friend from UP, Calmar Palma. Another friend from UP who came that day was Ding Aguila, not in the picture.
Roof is cogon, well arranged. Danny Paragas and his father Nong Endring Paragas looking.
This is the original treehouse in that tree, a small hut. It was dismantled so that the bigger, 2-storey treehouse could replace it.
