Renovation of wooden architecture
--- Residences to last for 100 years

Recently I often hear the phrase ‘think in units of 100 years.' I think the term points to the necessity of seeing things from a broader perspective in order to avoid being distracted by the incredibly rapid changes occurring in the modern world.

100 years, for example, is a unit of time equivalent to the span of about three generations. Three generations can be in one place during a period of 100 years, ‘inheriting,' ‘nurturing' and ‘passing on' heritage. Thus it is a matter of course that a house should last for 100 years.

If we regard timber as an architectural material, then timbers which last 100 years can be seen as the best choice. If new seedlings are planted when such trees are cut down, more trees can grow and become prime materials again in 100 years' time. If an architect uses timbers of such quality that they can last 60 years, and enhances them for a durability of 100 years, the trees can stay in the forest 40 years longer, and the amount of green in nature will increase. While trees grow they absorb and store carbon dioxide. The greater the volume of green, the more carbon dioxide gas will be absorbed and the more the earth will be healed. So wooden architecture with a long durability has a great environmental value.

Even today there are a number of traditional wooden houses which have lasted more than 100 years. However, few are in their original form. Houses made of wood in Japan endure through frequent repair, remodeling and expansion. The structure itself was designed with a traditional wisdom that makes it easy to repair and remodel. In order to preserve a house, it will be necessary to retile the roof and repair the walls as well as remodeling and expanding in response to changes in life style.

Renovating traditional architecture to suit the times has been a natural part of life since olden times. This is a means of creating a new tradition and passing it on to the next generation. This cycle of tradition continues today.
