かつて日本最初のフィンランド式サウナ施設である「スカンジナビアクラブ」があった渋谷に50年以上の時を経て誕生した鉄骨3階建てのサウナ施設である。近年のサウナブームのきっかけとなったマンガ＆エッセイ『サ道』の著者であり、日本サウナ・スパ協会任命「サウナ大使」を務めるタナカカツキ氏が初めて総合プロデュースを行うサウナとして我々は計画の初期段階からデザイナーとして参加した。
収支計画から割り出された３層ヴォリュームの１階にワークスペースとレストラン、２・３階に８種類のサウナ室と２種類の水風呂、緑に囲まれた外気浴スペースを計画した。昔ながらのサウナのイメージを払拭すべく「ウェルネス」や「メディテーション」をコンセプトとして、身体に優しくリラックスできる・清潔感があり洗練されているデザインを心がけた。サウナ室と水風呂は大使と企画チームと一緒にそれぞれコンセプトを立て、素材の使い方や各部の細かな寸法を様々な分野のプロフェッショナルと詳細に検討し、サウナの聖地フィンランドやリトアニアへの視察で得た知見もふんだんに盛り込みながらつくり込んでいる。全体の仕上げや造作家具は触覚の心地よさを意識したマテリアルとディティールを選択した。天板やベンチの角を大きく取った曲面や、柔らかく滑りにくいゴムチップの床、肌の触れる部位に応じて仕上げ方を変えた浴室仕上げの石など「触れる」ということにフォーカスしてデザインしている。また、館内の家具や看板、ソープホルダーなどの細かな什器まで一貫してデザインすることで上質で非日常的な世界観をつくっている。多くの情報に晒される現代人を思考の世界から感覚の世界へ開放し心身をととのえる、都会のオアシスが誕生した。

This three-story steel-frame sauna facility was established in Shibuya where the Scandinavian Club, Japan’s first Finnish-style sauna facility was located more than 50 years ago. This is the first sauna to be comprehensively produced by Mr. Katsuki Tanaka, a sauna ambassador appointed by the Japan Sauna and Spa Association, as well as the author of the manga and essay ‘Sa-do’ which triggered the recent sauna boom in Japan. We participated as designers from the initial planning stage.
Based on the income and expenditure plan, we created three floors: a workspace and restaurant on the first floor, eight types of sauna rooms, two types of water baths, and an outdoor air bath space surrounded by greenery on the second and third floors. We challenged the notion of traditional of saunas, by designing based on concepts of ‘wellness’ and ‘meditation’, aiming to offer a gentle, relaxing experience that is both clean and sophisticated. We created concepts for the sauna room and water bath respectively with Mr. Tanaka and the planning team, and worked in detail with professionals in various fields such as a sauna manufacturer and a sound system designer to determine the use of materials and the detailed dimensions of each part. The sauna rooms and water baths were created incorporating a wealth of knowledge gained from visits to sauna meccas such as Finland and Lithuania. The materials and details of the overall finish and the furniture were selected based on the concept of “comfort to the touch”. As a result, the table tops and benches have large, curved corners, the floor is made of soft, non-slip rubber chips, and the stone in the bathrooms is finished in different ways depending on where it touches the skin. By designing the furniture, signboards and down to the soap holders and small details in the building, we were able to create an extraordinary atmosphere. An urban oasis has been designed to free modern individuals from the overwhelming influx of information, guiding them from a realm of constant thought to one rich in sensory experience, while nurturing both body and mind.
