瀬戸内の凪を砕石と石畳で擬えた石の庭と雑木林。ロビーから望む「市中の山居」のようなこの風景はすでに完成されたものとしてあり、そこに加える喫煙所は、風景に静かに溶け込みながら、道後御湯らしい現代性をもつ特異点でなければならない。

喫煙所は通常、壁で囲われ、風景から切り離された場所に置かれる。そんな孤絶した場所での一服は、ほっとするどころか後ろめたさを抱えた贖罪の苦行のようですらある。庭という外部空間、しかも公共の動線から少し離れた場所でなら、喫煙所という場所をこの孤絶から解放し、風景や環境と互いに心地よい距離感を持った場所がつくれるのではないかと考えた。

その答えとして、偶然の手さばきが生む自由さと冷たい合理性の間、作為と無作為の間の僅かな隙間を狙って生まれたのが、この鋼板の折り紙である。5トン弱の質量も、積み重ねた思考の重さも感じさせず、前からそこにあった庭石の一つのように周囲の樹々や空気をやわらかくまとうその物体は、風景に溶け込みつつも微かなシュールレアリスティックな異物感を漂わせ、新たな風景の点景となった。

中に腰掛けると、外観の印象とは違い、ほどよく包まれる安心感がある一方で、大きく開かれ、煙は緩やかに上昇する天井の稜線に沿って空へと吸い込まれていく。不整形な窓のような正面の開口は庵を囲む樹々を切り取り、枝葉の影がムラのある利休鼠のグレーの壁に揺れる。この場所でしか得られない風景が確かにそこにある。

竣工後、煙草を吸いに庭へ出る宿泊客は目に見えて増えたという。時代の流れからすると微妙な結果ではあるが、建築家としては素直に喜びたい。

Ensho-an (Crystalized Smoke Hermitage) is a small smoking hut added to a corner of the garden at Dogo Miyu, a hot-spring luxury hotel in Dogo district in Matsuyama. Folded like origami from a single sheet of steel, it was conceived to turn a smoking area from a facility that is merely "there because it has to be" into a place that "should be there."

A stone garden of crushed rock and paving that evokes the calm of the Seto Inland Sea, and a grove of mixed trees. Seen from the lobby, this "mountain retreat in the city" already stands as a flawless landscape in its own right. A smoking hut added to it must melt quietly into the scenery while remaining a singular point with the contemporary character that is Dogo Miyu's own.

Smoking spaces are usually walled in and placed apart from the landscape. A smoke taken in such an isolated spot is anything but a relief; it can feel like an act of penance, even laden with a sense of guilt. In a garden, an outdoor space set slightly apart from public routes, we thought it might be possible to free the smoking area from this isolation and create a place that keeps a distance/closeness from the landscape and its surroundings that is comfortable for both.

The answer is this steel origami, born of aiming at the narrow gap between the freedom that a chance flick of the hand produces and cold rationality, between the deliberate and the unintended. Showing nothing of its nearly five tons or of the thought stacked up within it, the object wraps itself softly in the surrounding trees and air like one of the garden's stones that has always been there. It blends into the landscape while giving off a faint, surreal strangeness, and has become a new accent within it.

Sit inside, and the impression differs from the exterior. You feel pleasantly enclosed and secure, yet the hut is wide open, and smoke drifts along the ridge of the gently rising ceiling and is drawn up into the sky. The irregular, window-like opening at the front frames the trees around Ensho-an, and the shadows of their branches sway across the unevenly-painted gray walls. A landscape found only in this place is unmistakably here.

Since completion, guests have reportedly been stepping out into the garden to smoke in visibly greater numbers. Not quite what the times would predict, perhaps, but a result an architect can happily accept.
