基地位於三和國小西側高差1.6公尺之低處空地，其東側擋土牆將校園切分為二，校園裡的活動不連續而受限。
回應基地周邊多層高程之地面與景觀，活動場採取兩段式建築體，底部為混凝土基座、上部採鋼構構架，讓建築體在尺度、重量感與秩序層面，作為環境（人造與自然）到活動場之間的調節者。
設計由基地的四個邊界底部切入，透過混凝土構造之可塑性，逐一在各個邊界對環境做出回應，建立一個鼓動活動連續性的基座。南側，水平厚牆承接地面力量，崁入地景中。大階梯平台打開東側擋土牆界線，引導東西向流動，延續鳳凰樹下遊戲場活力，成為舞台、座椅或階梯；西側「模仿」既有教室簷廊，退縮形成緩衝的懸臂簷廊空間。北側，模仿緊鄰的緩坡，橫向擴充出緩階梯，原本僵硬的邊界，被拓展為可自由橫向穿梭的空間。將四個邊繫結起來，基座成為廣場。
上半部鋼構棚架由西向東傾斜，以輕薄的雙鋼板樑帶出主方向性，讓人們視線沿著樑穿越活動場，抵達鳳凰木下的遊戲場，開啟多向度流動的活動與風景。屋面在傾斜過程中，漸轉為下垂曲線，在整體秩序裡，帶來另個隱藏中心，支持著底下活動場的凝聚角色。
棚子柔軟地覆下，與拔地而起的柱子相遇，在流動的環境中緊繫出場所核心，日常與儀式的場景時時浮現，如劇場般。
The site for the new activity space is an empty lot on the western side of the school and it is 1.6 meters lower from the main school ground. The eastern retaining wall divided the school ground into two therefore continuous activities throughout the entire school were limited.
Responding to the surrounding ground level differences and landscaping, the activity space is designed as a two tiered architecture form. The foundation of the structure is concrete and the upper part of the form is a canopy structure in steel. This allows the scale, the mass and the order of the architectural form to act as a mediator between the environment (nature and man-made) and the activity space.
The design is approached from the four boundaries of the site. Utilizing the sculpted nature of concrete, the design responds according to each of the site boundary conditions, building an inviting base for the activity space. On the Southern edge, the heavy horizontal wall takes on the weight of ground mass, carving into the landscape. The wide stepping platforms open up the retaining wall edge on the east. They direct the activity flow between the east and the west extending the energy from the treed playground. It can be used as an open stage, seating or as steps. The western edge mimics the existing corridor space of the classrooms. The architecture is set-back to generate a spatial buffer with cantilevered beams. The northern edge also mimics the nearby slope with a gentle staircase. This allows the previously “hard-edge” boundary to expand and it is transformed into an open thoroughfare for more activities. Connecting together all these four site boundaries, the foundation of the activity space can be established.
The upper steel roof canopy slopes down from the west to east utilizing the single-directional steel roof beams to suggest the main directional axis. The viewers’ attention is led from the beam through to the activity space below. Arriving finally at the treed playground at the lower end, the space opens up to allow for multi-directional activities and viewing. The sloped roof turns into a gradual downward curve. The roof is transformed into a hidden focal point In the overall architecture design system, creating a ‘stage’ for events below.
The gentle covering of the roof canopy is met with the columns from the ground, tying together the spatial core within this fluid place. The design threads together moments encountered between routine and ritual, as if encountering scenes of a theatrical performance.
