タを設置することが提案されるようになり。With the recent rise in land prices, residential land has become increasingly narrow and difficult to obtain. As a result, houses have increased in height from two to three stories, and there is a tendency for two generations to live together. In such houses, common areas such as kitchens and private rooms such as bedrooms are located on different floors, making it essential to have access between the first floors. This makes it difficult for elderly households to live there, and it also becomes troublesome to carry luggage into and out of the third floor. Therefore, it has been proposed to install elevators in such private residences.
