This 70-years old house was inherited from the owner’s aunt, who once bought the original structure to teach tea ceremony. Later a new living quarter was added to complete this wooden single-story home. The property had been left as storage for years and was largely damaged, yet the new owner chose to keep the old characters, despite cost and time, than to build a new. Inspired by his decision the renovation project began not to simply keep the old but rather to create a space where the old section merges into the new section in a harmonious way. The renovated house “Koumori-An” offers the concept of “Keeping Value” which no new house can imitate.
