Thai Volunteer Camp Hand-Builds School Toilet from Reclaimed Wood

Forty-one architecture student volunteers spent eleven days hand-building a toilet for Song Phi Nong Primary School in Suphanburi Province, Thailand — the first sanitary facility ever undertaken by the AKU ASA Volunteer Camp in its history of annual builds.

The camp, long a meeting ground where architecture students and local craftsmen exchange skills that fade from one generation to the next, had previously produced pavilions and multipurpose halls. AKU ASA 20 asked a different question: what remains to learn when the same building type is designed every year?

The volunteers arrived with almost no construction experience. The school needed a small sanitary facility, and its site offered little more than open ground shaded by a mature Nontri tree. Choosing a toilet as the year's project shifted the camp's focus from structure and space toward a discipline rarely addressed in student work — sanitary design, and how plumbing systems are shaped by both the building and its site.

The completed facility, named Phi Sorn Nong Toilet, was designed by SEP studio. The layout responds directly to its context. The shade cast by the Nontri tree and the site's natural airflow transform the in-between space linking the sinks and the toilet stalls into an area that can double as a place to cool off, rest, or play, rather than a purely functional corridor.

The materials carry their own history. SEP sourced reclaimed wood from the school's original building — a Chinese-style classroom constructed roughly sixty years earlier — giving the new structure a physical link to the school's own past. Every component was built by hand by the volunteers themselves.

The result is a modest building, but one that reframes what a student volunteer camp can teach: that architecture education extends beyond form-making into infrastructure, material reuse, and the patient transfer of craft knowledge from one generation to the next.

For SEP and the AKU ASA organizers, the project demonstrates that the most ordinary building types — a school toilet, built from another building's bones — can serve as a rigorous vehicle for construction learning. As the camp's question implies, the challenge for future editions will be finding the next untested building type.
