Constructed entirely with locally sourced wood waste, “Oikumene Church” erected in Sajau, East Kalimantan, Indonesia, is designed to conform to its natural environment. The unassuming project features a slatted facade made of Rimba, or teak, while the inner structure utilizes meranti. An open-air hallway wraps around the perimeter of the building that’s situated at the highest elevation in the region.
For the worship space, TSDS Interior Architects relied on the Dayak people’s “Rumah Betang” design concept, which is an elongated, single-room dwelling that must have entryways on the east and west sides. Varying roof heights improve airflow throughout the interior, allowing it to stay cool throughout the day when temperatures hover around 90 degrees Fahrenheit with more than 85 percent humidity.
