A radiating timber roof structure is displayed in a Buddhist temple in Japan

Persimmon Hills Architects, the Japanese architecture firm has just finished the construction of a Timber Kannondo, or in a layman’s term main hall to the Buddhist Houshouin temple for the town of Sugito located outside Tokyo. In a similar manner to the location, the temple that once had a historical central role in uniting the neighborhood, it has gradually lost its authority through the widespread commercialization of religious organizations and ceremonial occasions. in response to this context, the design team introduced an expressive open hall — the Houshouin Kannondō, adjacent to the pre-existing temple — which feels both spiritual and accessible, generating a modern religious institution to revitalize the spirit of the community.

through depopulation and changes over time, the planned site had become a large vacant lot, alienating the original temple from the rest of the town. with the new kannondō, or main hall, persimmon hills architects reintroduces a relationship between the houshouin temple and its context. due to careful consideration for the new volume’s relationship to the old, its organization in plan, and the size of its roof, approaching visitors can see the gate, the new hall, and the preexisting hall together as a visual composition. the team thus generates a natural continuation of the existing framework.

the new kannondō is most notably characterized by its structurally expressive roof, spanning the length of the hall without the support of a single pillar. with the design team comments on the use of the design strategy: ‘the gable roof of the temple is an image of a tree-like structure, because the gable roof of the temple is reminiscent of buddha’s enlightenment under the linden tree, and the structure is reminiscent of the landscape that the back light shines.’ elaborating on the project’s response to the transformation of religious institutions within local communities, the team continues: ‘by superimposing new values on building types that tend to be caught up in fixed ideas of religious facilities, it induces usage that is different from before, and from this new next values are born and overlapped again.’
