内部の枠加工に到達した「発寒の家Ⅲ」です。棟梁が一言・・「今回、枠多いわ」・・その一言でふと思い当たった。性能向上リフォームを行う上で間取りを大きく変えないことは大切なコツ。なので間取りはほぼ以前のままである。昔の間取りの特徴は収納より部屋数と扉の数を重視すること。理由は簡単で、家の共用通路部は基本寒いのが当時の常識だから廊下やホールに面する部屋には全て冷気が入らぬよう扉が必要となる。もちろん共用通路は寒いものと思い込んでいるから、廊下や階段＆玄関なんかは極力コンパクトに作ろうとなり易い。その結果益々通路以外の用途には適さなくなる。こうした共用部を勉強＆ホビーコーナーのような居室用途に拡大し使えるようにするには、寒さを除くノウハウの獲得と発想の転換の両輪が必要だ。リビング階段や吹抜は気持ち良さの反面、熱環境的には不利であると決めつける発想も何だか思考パターンが似ているなあ～と感じました。
This is ``Hasamu no Ie III'', which has completed the internal frame processing. The master carpenter said something like, ``This time, we have a lot of slots.'' Those words suddenly made me think. When carrying out performance improvement renovations, it is important not to make major changes to the floor plan. So the floor plan remains almost the same as before. A characteristic of old floor plans is that they emphasize the number of rooms and doors rather than storage. The reason is simple: it was common knowledge at the time that common passageways in houses were generally cold, so all rooms facing hallways and halls needed doors to prevent cold air from entering. Of course, people assume that common passageways are cold, so it's easy to try to make hallways, stairs, and entrances as compact as possible. As a result, it becomes increasingly unsuitable for uses other than passageways. In order to expand and use these common areas for living rooms such as study and hobby corners, it is necessary to acquire know-how to eliminate the cold and to change the way we think. I felt that the idea of thinking that living stairs and atriums are comfortable but disadvantageous in terms of thermal environment has a similar thought pattern.
上は昔風の間取り。設計者が断熱を十分理解していないと玄関や廊下の寒さを改善できないのでそれらを極力小さくまとめようとする。接する部屋にも冷気が入らないように全て建具（扉）で仕切りたくなる。その結果・・玄関廻りの収納も取り難くなるし、WCなどは狭くて寒い空間となり易い。もちろんヒートショック等の事故も考えられる。要は若い時しか住めない家になってしまう。住宅は最低でも35年以上住むことを考えると、これは大問題。
Above is an old-fashioned floor plan. If designers don't fully understand insulation, they won't be able to improve the coldness of entrances and hallways, so they try to keep them as small as possible. You'll want to use fittings (doors) to partition all adjacent rooms to prevent cold air from entering. As a result, it becomes difficult to store storage around the entrance, and the WC tends to be a small and cold space. Of course, accidents such as heat shock are also possible. In short, it becomes a house that you can only live in when you are young. This is a big problem considering that people will live in a house for at least 35 years.
最近の間取りは断熱の効果を十分生かして広々とした一室空間が可能。階段がリビングにあっても、もう冷気を気にする必要はない。つまり間仕切りの必要性は寝室だったり、脱衣だったり寒さ以外の必要性で決めればよくなる。その結果、室内は広々として建具とそのための枠が減る。棟梁が言うのはいつも作っている間取りと違うねという意味でした。
Recent floor plans take full advantage of insulation to create a spacious room. Even if the stairs are in the living room, you no longer need to worry about cold air. In other words, the need for partitions can be decided based on needs other than bedrooms, changing clothes, or the cold. As a result, the interior becomes more spacious and there are fewer fittings and frames for them. What the master carpenter meant was that the floor plan was different from what he usually creates.

HSCC is cool today after a long time
