office K2

空気を設計する

半径5km圏内の在宅訪問診療を担う医療事務所である。医療従事者の健康を支えるため、法定の衛生基準を大きく上回る、一人当たり25㎥の気積を確保し、良質な空気環境を実現した。階高4.9mの豊かなボリュームを最大限に活用し、構造には幅105mmの住宅用集成材を採用。資材価格が高騰する時代においても入手しやすい一般流通材を用いながら、大らかな空間を構築している。長時間を過ごす執務環境として、窓辺のデスクや南面のサンルームなど、多様な居場所を計画した。時間帯や天候、季節の変化に応じて、利用者が心地よい場所を選択できる。ウィズコロナ時代において、建築に何ができるのか。自然通風や自然採光といった素朴な手法を通して、人の健康と環境を支える建築の新たな役割を問いかけている。

Designing the Air

Office K2 is a design-driven project that reimagines the workplace for the post-pandemic era. Through a generous timber structure, it creates a spacious and airy environment that maximizes natural ventilation and daylight, enhancing the health and well-being of its occupants. This medical office supports home-visit healthcare services within a five-kilometer radius. To promote the well-being of healthcare professionals, the building provides 25 m³ of air volume per person, significantly exceeding standard hygiene requirements and creating a healthier indoor environment.

The design takes full advantage of a 4.9-meter floor-to-ceiling height while utilizing 105 mm-wide timber members commonly used in residential construction. By employing readily available materials during a period of rising construction costs, the project achieves a sense of openness and spatial generosity with remarkable efficiency.Recognizing that staff spend long hours indoors, the office offers a variety of places to work and relax, including desks overlooking the surrounding landscape and a south-facing sunroom. Occupants can choose their preferred setting according to the time of day, weather, and seasonal conditions.

What can architecture contribute to human health and well-being in the post-pandemic era? Through simple yet effective strategies such as natural ventilation and daylighting, Office K2 explores a renewed role for architecture in shaping healthier and more resilient environments.
