Stone based building

3. As small as possible
How much space is necessary for human?
Perhaps it is 'rich' enough to be satisfied even if it is small?
Most of the simple cedar houses are within 100 m².

Tiny house

As long as possible, as low as possible
IIt has long been said that "It is important to take the eaves deeply" in Japan, where it has much rainfall compared to Europe.
It can be said that from the fact it reads "Eaves (Hisashi)" and "Shields (Kabau)",
欧州に比べ雨量の多い日本では昔から「軒は深くとる」ことが大切であると言い伝えられてきました。「庇（ひさし）」と書いて「庇う（かばう）」と読むことからもそのことがうかがえます。

For example, if you go to the Yoshino district of Nara, a house with a deep owl is common, and there are house with 3.6m long eaves around the foot of Yatsugatake mountain in Yamanashi.
例えば奈良の吉野地方に行けば軒の長さがikkenn(1.8m)ある家が普通ですし、山梨の八ヶ岳山麓ではniken(3.6m)ある家もあります。

We adopt "climbing beam structure" for the roof structure.
小屋組には「登り梁構造」を採用しています。

By loosening the roof gradient as low as possible it is not as low as to prevent the eaves from obstructing the line of sight from the indoor side despite the deep eaves.
また屋根勾配を緩くすることで深い軒の出にもかかわらず軒先が室内側からの視線を妨げるほどには低くなリません。

Because the roof construction is nearly horizontal, the height of the roof can be kept low, the weight of the roof will be lighter, and it will be less susceptible to the strong wind caused by the typhoon.
屋根構面が水平に近くなるため屋根の高さを低く抑えることができ、屋根重量は軽くなり台風による強風の影響も受けにくくなります。

Cedar thick plate (thickness 40 mm) is used for the sheath board.
野地板には杉の厚板（厚み40mm）を使用します。

Since the space between the climbing beams can be expanded to 1.8 m, it is possible to drastically reduce the number of members as compared to a general roof structure, and furthermore, members such as climbing beam / ridge / girder are all " Combined with, it becomes a strong roof structure, and its neat beauty can be seen from inside and outside the house.
登り梁の間隔を６尺（1818mm）まで広げることができるため、一般的な和小屋に比べて仕口数を大幅に減らすことが可能となり、さらには登り梁／棟木／桁等の部材がすべて渡りアゴで組み合わさることで強固な小屋組となり、その端正な美しさを家の外からも中からも見ることができます。

In "Simple Cedar House" we protect the outer wall from rain by taking sufficient eaves out so that direct sunlight in the summer does not heat the ground in front of the indoor or south opening.
Unless there are physical or legal restrictions, we are trying to ensure that the eaves are about 1.8 meters southeast.
「シンプルな杉の家」では軒の出を十分にとるとで雨から外壁を守り、夏場の直射日光が室内あるいは南側開口部前の地面を熱することがないようにします。
物理的あるいは法的な制限がない限り南側に1.8m程度の軒の出を確保するようにしています。（参考：南中時の太陽高度／夏至：約77゜、冬至：約31゜）
