Example: Building a New Kyo-Machiya House

(In the case of a house with two or fewer floors in a quasi-fire zone) 

When building a new house, it is required to conform to the current regulations. 
Traditional wooden buildings, such as Kyo-Machiya, can also be built in compliance with the current regulations on structural durability and fire prevention. 

Example: a newly built Kyo-Machiya house using the traditional axial construction method 

Fire Prevention

• The eaves of the building can be made of wooden panels (*1).​

• The exterior walls can be painted with earth or covered with wooden boards (*1). 
• ​If fire prevention equipment is installed on the inside, a wooden lattice can be placed on the outside. 
• Fire prevention equipment of the specifications that conform to the Notification can be covered with wood on the surface. 

⇒A new house can be built with the design of a traditional Kyo-Machiya.

*1: The specifications must conform to the Notification and be approved by the Minister. 

Structure 

• If the structural safety of the building is confirmed by calculating the maximum load capacity, it is possible to build a new house using the traditional masonry construction method. 
• If the long-term allowable load-bearing capacity of the ground is 70 kN/m2 and any of the following applies, a house can be built on stone footings without calculating the maximum load capacity. 

1. a building with one floor, where footings are used
2. a building with its pillar and foundation connected by dowel joints, where it is confirmed that no tensile force that would interfere with the structural capacity is generated.

---

• As the structural durability of earth-painted walls is specified in the Notification, it is possible to design a house by taking into account the durability of earth-painted walls without using the limit capacity calculation. 

⇒ It is possible to build a new house using the traditional framework construction method. 

Procedural Regulations

• Application for building permit is required. 
• Application for interim inspection is required. 
• Application for completion inspection is required.
