This house was built in a residential area in the city center, which is a quasi-fireproof zone, and wooden sashes were used even in areas where there is a risk of fire spreading. This double-glazed wooden fire door was researched and developed by the "Iezukuri-no-kai" and certified by the Minister of Land, Infrastructure, Transport and Tourism, and this is the first house to use it.
