Mengenai Komazawa Daigaku Stesen Kereta Api

Komazawa Daigaku ialah stesen kereta api yang diperbaharui, terletak di bawah Taman Komazawa di Setagaya, Tokyo. Konsep Under the Park (Di Bawah Taman) menganggap konkors bawah tanah sebagai akar dan bangunan pintu keluar sebagai pokok simbolik. Komponen stesen dikelompokkan mengikut tiga skala masa: kerja tanah kekal, pokok yang menua dan daun yang diperbaharui. Jubin sedia ada dan lantai terazo dikekalkan untuk mengurangkan sisa, dan kayu tempatan digunakan. Salutan siling logam mewujudkan kesan cahaya berbintik. Bangku dan kaunter mengundang orang ramai untuk berehat dan bertemu.

Ciri-Ciri Unik: This project's uniqueness is its "Under the Park" concept, which creates a consistent narrative for the entire space: the underground concourse is envisioned as the town's "roots," and the buildings as "symbolic trees." Furthermore, a unique design methodology redefines the station via three timescales: "permanent earthworks," "aging Trees," and "renewing leaves." This presents a new vision for an adaptable station designed to be loved long-term.
Dimensi & Pembungkusan: Total Floor Area:
Underground Station Concourse: Approx. 6,500 sqm (RC structure, 2 floors below ground)
East Exit Building: 564.34 sqm (RC structure, 4 stories above ground)
West Exit Building 1: 398.58 sqm (Steel structure, 2 stories above ground)
West Exit Building 2: 346.80 sqm (Timber and partial RC structure, 4 stories above ground, 2 floors below ground)

Teknologi Pengeluaran: This project’s realization is driven by sustainability. We minimized waste by preserving existing tiles and terrazzo floors, while using domestic timber for its warmth and environmental benefits. The West Exit building, in a fire protection district, pioneers advanced timber tech like LVL fire-resistant coating and a two-way rigid-frame structure (rare in Japan). A special metallic ceiling coating creates a unique komorebi (dappled sunlight) effect.
Cabaran Reka Bentuk: Our greatest challenge was maintaining the consistency of the "Under the Park" concept across a four-year project with diverse work areas and many stakeholders. Amidst fragmented on-site decisions, our "Earthworks, Trees, and Leaves" design guideline served as the core guiding principle to return to. Additionally, realizing a timber station building in a fire protection district was a major external challenge, requiring us to overcome strict legal regulations and technical constraints.
Penyelidikan: This practical research aimed to translate the given "Under the Park" concept into a sustainable space, creating new value for aging infrastructure. Our methodology was to develop the "Earthworks, Trees, and Leaves" model, which classifies station components by three timescales. Based on this model, we selected materials and composed the space, prototyping advanced timber technology in one building. The expected social impact is increased user dwell time, fostering affection for the station.
Inspirasi: The primary source of inspiration for this project is its very location: "under Komazawa Park." We were strongly motivated by the desire to transform the aging, inorganic underground space—a place people have used daily for over 45 years—into a more comfortable and cherished environment. Therefore, we placed the "park," a quintessential landscape shared by all local residents, at the core of our concept. We envisioned that just as the trees in the park extend their roots underground to support their lush forms above, the station could also become like a living organism—absorbing, nurturing, and radiating the town's vitality. This poetic vision of "Under the Park" became the driving force behind the entire design.
Tempoh Projek: This project was implemented at Komazawa-daigaku Station in Setagaya, Tokyo, as the first phase of the "Green Under Ground" renewal project by Tokyu Railways Co., Ltd. The schematic design phase began in August 2020, and the overall construction period for the station runs from July 2020 to March 2025. Completion is on April 1, 2025.
Aliran Operasi: Visitors are guided by the "Symbolic Tree"-like station buildings into the "Under the Park" world. Descending warm, trunk-like staircases, a space unfolds resembling the roots of a park, seemingly bathed in dappled sunlight. This functions not merely as a path to the trains, but as a "garden" for people to spend time as they wish. Intentionally placed benches and counters invite users to linger, meet or rest, generating a new, personal interaction with the station itself.
