札幌平屋亭（Hiraya Pavilion in Sapporo）丨日本丨YKAA

该项目构想为一个小型多功能亭与工作室，其起点源于一个简单的问题：如何在有限的占地面积内创造开阔与慷慨的空间感，同时保持低成本？

Conceived as a small multifunctional pavilion and studio, the project began with a simple question: how can we create a sense of openness and generosity within a limited footprint while keeping costs low?

项目基地位于一块狭长而略带坡度的地块上，汇聚了对比强烈的场地条件：高架公路、输电塔与繁忙的道路界定了人工环境，而真駒内河、自行车道及周围的绿地又重新引入了自然的气息。

The site lies on a narrow, gently sloping plot where contrasting conditions converge: elevated highways, transmission towers, and busy roads define a human-made environment, while the Makomanai River, a cycling path, and the surrounding greenery reintroduce a sense of nature.

在这样的环境中，业主希望拥有一个突破传统定义的小型多功能空间。由此诞生了“Hiraya”：一个多用途亭，一个用于聚会、交流、共享日常与梦想的场所。为了应对多样的使用者与灵活的功能，我们设想了一种能够在时间中持续生长的建筑形态——柔韧而坚韧，既滋养建筑的持久性，又能灵活适应变化。

Within this setting, the client sought a small, multifunctional space that transcends conventional definitions. Thus surges Hiraya – a multipurpose pavilion, a place for gathering, conversation, and shared everyday life and dreams. Anticipating diverse users and fluid functions, we envisioned a structure capable of thriving in this world over time – a soft yet resilient form that nourishes architectural longevity while adapting flexibly to change.

建筑由一个4550毫米见方的单一空间和一个最小化的服务核心构成。在这一极为紧凑的占地内，我们探索了如何在尺度与成本的限制下实现开放性与灵活性的共存。

The building consists of a single 4,550 mm square space and a minimal service core. Within this extremely compact footprint, we explored how openness and flexibility could coexist with the constraints of scale and cost.

建筑体量下沉720毫米以形成基座，四周均设有开口。这一低矮的平台鼓励多样的身体姿态、与活动，如行走、坐卧、工作与用餐，同时将周围的绿意引入室内，形成连续的水平流动。

The volume is set 720 mm into the ground to form a plinth, from which openings extend on all four sides. This low base encourages a variety of postures and activities such as walking, sitting, working, and eating, while drawing the surrounding greenery into the interior and providing a continuous horizontal flow.

空间中心设有一根旋转45度的标志性立柱，与一根对角梁交汇以抬起上方的小型阁楼地板。这一剖面构成通过四周的连续空隙连接上下区域，扩展了垂直方向上的开阔感。

At the heart of the space, a symbolic column rotated 45 degrees intersects with a diagonal beam that lifts a small loft floor above. This sectional composition connects the upper and lower areas through continuous voids on all four sides, expanding the vertical sense of openness.

尽管4550毫米的跨度完全可以用一根梁实现无柱空间，但那样的举措在此显得比例失衡。相反，中央立柱与对角梁共同作为空间锚点，在紧凑的平面中微妙地划分出四个独立却相互关联的区域。

Although a 4,550 mm span could easily be bridged with a single beam to achieve a column-free space, such a gesture would feel disproportionate here. Instead, the central column and diagonal beam act as the anchor,  subtly articulating four distinct yet interrelated zones within the compact plan.

在这种模糊的环境中，“Hiraya”形成了一个小而自足的宇宙：一个拥抱变化、鼓励诠释、并在精准的建筑框架中提供宁静自由的空间。

In this ambiguous environment, Hiraya forms a small, self-contained universe,  one that embraces change, invites interpretation, and offers quiet freedom within a precise architectural frame.
