シンガポールのすぐ南に位置するインドネシア・バタム島にある店舗です。かつて施主が自ら設計した店舗を改修しました。改修にあたっては、バタムに多い「ルコ(shop-house)」という商業建築の形式にとらわれず、空間そのものの価値を重視しました。自社ブランドの発祥の地を大切にしたいという施主と対話するにつれ、実用性優先で人工素材に囲まれた環境が増えるバタムの街の中で、自然素材を用いた、静かで繊細な空間体験を大切にしました。

建物に近づくと、真っ白でミニマルなファサードが出迎えます。外観は内部の様子をほとんど想像させません。ミニマルな形態と抑制の効いたテクスチャーを持つファサードが、周囲と調和しつつも静かに強い主張を放っています。

一般的なルコでは珍しく、建物全体を貫く2層分の吹き抜けがあり、2階と3階をつないでいます。中央の吹き抜け部分には、既存のコンクリートの構造フレームがありましたが、そのまま残すことでほどよい空間の分節が可能となりました。その上には同じ長さの天窓があり、そこから自然光が差し込みます。大きな開口部から空だけを切り取ることで、賑やかな街の喧騒から距離を置くことができます。天窓や中庭周辺に隠された樋は、雨水を室内に取り込む仕組みになっており、閉じられた空間に自然の開放感をもたらしています。

ITSUMOの各店舗に独自のアイデンティティを持たせることも重要な目的の一つでした。バタム店には、他の店舗とは対照的に、より厳格でシャープな幾何学的デザインが求められました。主なカラーには黒を採用。静かで繊細ながらも自信と豊かさを感じさせてくれます。ただし、内装の大部分を黒にすることで、暗く沈んだ印象にならないよう、石、金属、木材など、自然由来で黒色や着色が可能な素材を徹底的にリサーチし、無垢のグレーコンクリートとさまざまな黒やブラウンの素材を組み合わせることで、調和と奥行きを生み出しました。

ITSUMOは強いメッセージを放っています。「意味のある建築は場所を超える」。機能性を優先しがちな現実的なバタムの街なかにおいてさえ、思慮深く革新的なデザインがふさわしいと私たちは信じています。ITSUMOというプロジェクトは、どんな文脈においてもデザインが人々を刺激し、限界を押し広げるものだという私たちの答えです。

The renovation of the ITSUMO dessert shop in Batam was a collaborative effort, aiming to challenge local architectural norms. This site’s significance stems from it being the client’s first shop, which she originally designed herself. The aim was to elevate architecture’s perception within its typical ruko (shop-house) context.

The client’s vision for a bold statement where the brand originated fueled the project. This meant crafting a design distinct from Batam’s utilitarian, rapid-development architecture. In Batam’s bustling environment of vibrant, colorful, artificial materials, we aimed for the antithesis: a quiet, subtle experience grounded in natural materials.

Approaching the building we are greeted by a striking white minimalist façade giving away little of what to expect inside. This approach required care: minimalist forms and a restrained, textured facade achieved a quiet statement which was expressive, but still harmonized with the neighborhood.

Upon entering, visitors are struck by the three-dimensional nature of the space—unusual for a typical ruko. A two-story void cuts through the entire building, connecting the 2nd and 3rd floors and is topped by an equally long skylight – the sole source of natural light.

This was inspired by the client’s love serene atmospheres and rain. Framing only the sky with the main opening creates a sense of distance from the busy city. Hidden gutters around the skylight and in the courtyard allow rainwater to flow through the interior, adding the sense of openness and nature to the perfectly sealed space.

The existing concrete structural frame remains exposed in the void’s center. This frame resembles a cage, framing different spaces. Rather than viewing it as an obstacle we believe it introduces necessary complexity and ambiguity to an otherwise straightforward space. Aesthetically, it is the centerpiece; symbolically, it is a reminder of the local architectural context.

Another key driver was giving each ITSUMO location a distinct identity. Batam’s brief demanded stricter, sharper geometry—an intentional contrast with other locations. Black was assigned as the main color. We drew inspiration from avant-garde Japanese fashion’s layered textures – quiet and subtle, yet confident and rich. The predominantly black interior needed to avoid feeling somber. The team researched naturally black or stainable materials like stone, metal, and wood. Juxtaposing raw gray concrete with varied black and brown elements created harmony and depth.

The unusual dynamic of complete client trust also presented a challenge. Accustomed to constraints, we found rare artistic freedom. This shifted our internal process, making us our own critics. It was a profound exercise in translating a client’s essence through our artistic lens.

Ultimately, communication and iteration defined ITSUMO. Consistent dialogue between architects, client, and contractor was crucial. Exploring numerous options for every detail, proved vital. The dedication of the craftsmen at Room Studio, producing countless samples, was key to achieving the desired feeling.

In essence, ITSUMO makes a powerful statement: meaningful architecture transcends location. Despite Batam’s identity as a pragmatic city prioritizing function over expression, we believe every place deserves thoughtful, innovative design. Our response, embodied in ITSUMO, is that such design inspires and pushes boundaries, regardless of context.

ITSUMO is a catalyst, aiming to challenge assumptions. The project reshaped our approach, highlighting the impact of trust, the value of collaboration and architecture’s power to elevate the ordinary.
