double-layer timber facade enfolds renovated public toilet in korea by daniel valle architects

Daniel Valle Architects Renovate Public Toilet near Lake in Daegu

Located on the southern edge of Susongmot Lake in Daegu, South Korea, a public toilet facility dating back to the 1990s has been renovated by Daniel Valle Architects to meet current functional and environmental standards. The project redefines the relationship between built form and its natural surroundings through structural adaptation and material choice.

The renovation prioritizes openness, daylight access, and integration with the landscape. Several original concrete and stone walls were removed, allowing natural light to penetrate deep into the interior. In their place, a new double-layer timber facade was introduced. Comprising 450 vertical studs set at alternating inclinations, the facade allows light to enter while maintaining visual privacy.

Daegu Public Toilet adapts to seasonal changes in the landscape

The design team at Daniel Valle Architects develops the timber structure to support ecological interaction over time. Climbing plants are expected to gradually grow over the facade, visually embedding the building into its setting. Bird nests have been incorporated between selected studs, enabling the structure to function as a small-scale habitat in addition to its public utility role.

This combination of material strategy, ecological accommodation, and spatial reconfiguration transforms a utilitarian facility into an adaptable element of the lake’s public infrastructure, responsive to both seasonal change and long-term environmental growth.
