There is Life After Demolition: Mass Timber, Circularity and Designing for Deconstruction
The first Shikinen Sengu was held in the year 690, in the city of Ise, Mie Prefecture, Japan. It consists of a set of ceremonies lasting up to 8 years, beginning with the ritual of cutting down trees for the construction of the new Ise Shrine and concluding with the moving of the sacred mirror (a symbol of Amaterasu-Omikami) to the new shrine by Jingu priests. Every 20 years, a new divine palace with exactly the same dimensions as the current one is built on a lot adjacent to the main sanctuary. Shikinen Sengu is linked to the Shinto belief in the periodic death and renewal of the universe, while being a way of passing on the ancient wood construction techniques from generation to generation.
Mass timber components for this project were prefabricated offsite which not only aids in the ability for on-site assembly but also aids in the disassembly of projects in the future if needed. Timber's versatility allows it to be disassembled and then reassembled into other buildings and furnishings, sequestering carbon for longer so long as it stays out of the landfill.

The idea of creating a building that will have an expiration date is not a common one. In fact, the useful life of a structure is often given little consideration. When demolished, where will the materials go? Will they be disposed of in landfills or could they be reused in new projects? There are certain construction methods and materials that make this process easier. Others make reuse unfeasible, due to several factors.
