The office of the Hasami pottery brand Maruhiro is a project to renovate an 86-year-old Japanese house located just behind "Hiroppa", a complex project including a park and directly-managed store currently under planning at DDAA.


Hasami pottery is a local industry in Hasami, Nagasaki Prefecture.By adding the park a function of directly-managed store, Hiroppa is planned as a plaza for not only customers but also local people.In an old house adjacent to the park, a showroom, a kitchen for making lunch boxes to eat in the park, and residence space for collaboration with artists were created in addition to office functions.


When this project was just starting, the COVID-19 calamity was spreading worldwide, but the client decided to continue the project since the park project, which is for outdoor use, would be beneficial even under post-COVID conditions. However, as the future is unpredictable, it is very important to be flexible in terms of organization management. Therefore, DDAA proposed what they could do with half of the original budget. The goal was to boldly change the impression of the existing one with as little modification as possible and also to create a space that is not fixed in function or concept.


Japanese Wooden houses are designed to allow for flexible and repeated expansion and renovation in the first place. It can be said that one of the characteristics of Japanese housing is that it does not peak at the time of completion, but can gradually change its appearance according to the situation. This Japanese house was no exception and the kitchen, warehouse, entrance, and so on had been extended.


DDAA proposed to make as few changes as possible to the existing conditions and to remove the floor from the room where the tatami mats were laid. The floor was removed and concrete was poured, leaving the magnificent stone plinth foundation that appeared. Along with the concrete floor, the legs of the desk at the height of the original floor were provided also in concrete.


Using a chair often cause damage to the tatami, but removing the tatami solved the problem, and at the same time, the ceiling height was raised as the floor was lowered.All the paper and glass were removed from the yukimi-shoji screens (lattice frame with translucent paper on top and glass on the lower part so that you could look out at the garden when sitting on tatami mats). Since the floor has been lowered, the garden is at eye level when sitting on a chair. The tokonoma (Japanese alcove, which is often decorated with hanging scrolls and other art piece), which came to a relatively high position, also suits the gaze of modern life, where we often sit in chairs. A rolling round mirrored door that also serves as a sign for the entrance was installed on the existing shoji frame.


On the second floor, tatami mats were replaced with wooden boards to create a residence space for artists. The wall below the nageshi (decorative material that connects columns horizontally) is covered with the same lauan plywood as the floor, and no additional work has been done above that.


By slightly changing its relationship, the original meaning can be altered. We believe that this is an effective way to utilize existing stock, such as vacant houses. After completion, plans to use it not only as an office, but also as a tea shop adjacent to the park, a pop-up store, and a rental space have immediately surfaced.

波佐見焼陶磁器ブランドのマルヒロのオフィス「おうち」は、現在DDAAで計画中の公園と直営店などの複合プロジェクト「HIROPPA」のすぐ裏手にある築86年の日本家屋のリノベーションのプロジェクトだ。


 


波佐見焼とは長崎県波佐見町の地場産業で、直営店に公園の機能を付加することで、顧客だけでなく地元の人たちにも利用してもらうための広場として「HIROPPA」を計画している。その公園した隣接した古民家にオフィス機能だけでなくショールーム、公園で食べるお弁当をつくる厨房、アーティストなどとのコラボレーションのためのレジデンススペースを作る。


このプロジェクトがちょうどスタートしたころ、新型コロナウイルス感染症が世界的に拡大したが、屋外用途の公園のプロジェクトはアフターコロナも有効であろうため、クライアントはプロジェクトを継続することにした。ただし、将来の予測がむずかしいいま、組織のあり方としても会社経営としても、フレキシブルであることはとても重要だ。そのため、僕たちは当初の予算の半分でできることを提案した。


目指したのは現状のものにできるだけ手を加えないで、大胆に印象を変えること。また、機能やコンセプトを固定させない空間を作ることだ。


 


そもそも、木造の日本家屋はフレキシブルに増改築を繰り返すことができるつくりだ。竣工時にピークを迎えるのではなく、少しずつ状況に合わせて姿を変えられるところが、日本家屋の特徴だともいえる。今回対象となった日本家屋もその例にもれず、キッチンや倉庫、玄関などが増築されていた。


DDAAの提案はできるだけ既存の状態に手を加えず、畳の敷かれていた部屋の床を抜く、それだけである。床を取り払い、現れた立派な束石を残しつつ、土間コンクリートを打った。土間と合わせてコンクリートの立ち上がりを設け、もとの床の高さのテーブルの脚にした。畳の上で椅子を使うと畳を傷めてしまうが、畳を取り外すことでその問題を解消し、同時に床が下がったので天井高も確保される。


畳に座ったときに庭を眺められるよう下部にガラスがはめ込まれた雪見障子は、ガラスと障子紙をすべて取り外した。床が下がったことで椅子に座ったときの視線の高さに庭園が広がる。少し高くなった床の間も、椅子に座ることの多い現代の生活の目線にフィットする。既存の障子枠を使って、エントランスのサインも兼ねた転がる丸い鏡の建具を設えた。2階は、アーティストのレジデンススペースとして、畳を板に敷き直した。長押より下の壁面に床と同じラワン合板を貼り、それより上には手を加えていない。


 


関係性を少しだけ変えるだけで、元々の意味を変化させることができる。空き家など、既存ストックの活用するための手法として、有効な手立てだと考えている。竣工後、早速オフィスだけでなく、公園に隣接するお茶屋さんにする、ポップアップショップやレンタルスペースとして使う計画が浮上している。
