Despite Thailand being on the East Asian-Australasia Flyway (EAAF) and having 996 species of migratory birds recorded, they are disappearing steadily for a number of reasons: death from pesticides, hunting, climate change, and contamination of water bodies.

These compact structures reminiscent European silos with open-faced brick façade. Demolishing these structures would be a huge waste of resources; hence, many of them have been turned into rooms for “Kaomai Lanna” boutique hotel. Visitors who stay at Kaomai Lanna are typically eco-conscious. To augment the experience of their stays, additional abandoned barns are redesigned to be learning facilities for bird studies. The Learning facilities welcome visitors with real life examples of our impact on avian populations and accompanied by animated and printed graphics and manuscripts. These 70-year-old bricks tobacco curing barns are the last of its kind in Thailand. Chiang Mai Bird Sanctuary will preserve a curing barn in its original conditions —allowing visitors to get a glimpse of history of the tobacco industry. Rising spiral wood structures and platforms are inserted inside—allowing visitors to step up and observe the architecture, the floating information panels and screens, which tell history and curing process. Instead of paving over the original sand floor inside the curing barn, a white epoxy coated fiber-cement floor is placed freely in the middle to be use as projecting screen viewing in a bird eye view. MUSEUM Bird Haven EVERTHING HAPPENS WITHIN 6 METRES Site B This piece of property had been laid out for a real estate development. All roads within the master plan are 6 meter wide and constructed with water drainage systems in place. Only 3 demo-homes were constructed for prospective homebuyers, which never materialized. The development of Bird Sanctuary capitalizes on this existing footprint, and focus on the 6 meter street width—“Everything happens within 6 meters”. We confine new constructions on the existing footprint —not encroaching on the open land and giving more space to wild birds. Viewing Tower, Meditation Pods, Viewing Platforms and information center are all integrated into existing infrastructure. Roads become site drainage systems, visitor routes as well as foundations for added facilities such as meditation rooms.

First, its availability: an abundant volume of 5 million tons of palm bunches are discarded annually in Thailand (world’s 3rd largest palm oil producer), alternative uses for this growing waste could create great value. Currently, most of this agro-waste is NOT being utilized. Second, its insulating-capability: natural fibers have high insulating value, preventing heat from entering the buildings. Third, its compatibility with nature: small birds can use the fiber bunch as nestling pockets and habitat —even for hiding from dangers. And fourth, its moisture retention capability: fiber bunches retain moisture well and allow seeds to take roots and grow. This fiber skin can support food regeneration, a great food source for all birds in the area. 2015 • Ecology, Replanting & Re-Habitation • Wetland Viewing Platform 242 sq.m.
