「待續之界」一個持續回應環境變動的都市邊界體，藉由過去三百年間古城牆對應環境的演化去預演未來三十年內的邊界新姿態。
高雄左營舊城正在從原先的「城內聚落、城外荒野」逐漸走向「城內荒野、城外聚落」。在經歷了數次環境與城牆邊界的演變，現今多樣的古城牆殘跡看似凝固卻動態存在於城市之中，體現了「持續演化」的特質。而近年的古蹟保存提案多數著眼在型式與歷史上的回應， 忽略了這道邊界體的演化性，因此將基地選在尚未被定義的線性殘段，提出分為三階段的邊界實驗。
第一階段「容器」
城內的眷村尚未被遷移，設計運用聚落內傳統的農業行為。將城牆間的空白轉換為線性的溫室，重新定義消失的外牆，使其作為能夠包裹農業活動與自主循環的容器牆。
第二階段「見城」
城內的聚落遭到遷移，城外的眷改空地新建成高樓。設計將延續第一階段的原型，並承接既有的步道系統，讓繞行舊城的動線沿展。設計在城牆消失段置入數道混凝土墩牆，二點四公尺的模矩將都市的多樣收整在一道道框景中，作為反覆觀看原野與城市的構體。
第三階段「考古」
時間的更迭，新建的邊界體成為過去的遺構，木構因風化而銷毀，殘存的混凝土墩牆所帶出的生活痕跡，持續地展演時間的厚度。
“The Boundary of Continuation”
A continuous urban boundary responding to environmental changes, projecting the evolution of the boundary over the next thirty years by referencing the past three hundred years of the old city wall’s adaptation to its environment.
Kaohsiung’s Zuoying Old City is gradually transitioning from the original state of “settlements inside the city, wilderness outside” to “wilderness inside the city, settlements outside.” After undergoing several transformations in the environment and the city wall boundary, the various remnants of the old city wall, though seemingly static, dynamically exist within the city, embodying the characteristic of “continuous evolution.” Most recent heritage preservation proposals focus on responding to form and history, neglecting the evolving nature of this boundary. Therefore, the site is chosen at an undefined linear remnant, proposing a boundary experiment divided into three stages.
Stage 1: “Container”
The military dependents’ village inside the city has yet to be relocated. The design utilizes traditional agricultural practices within the settlement. The blank spaces between the city walls are transformed into a linear greenhouse, redefining the disappeared outer wall and turning it into a container wall that can enclose agricultural activities and self-sustaining cycles.
Stage 2: “Seeing the City”
The settlement inside the city is relocated, and high-rise buildings are newly constructed on the former military dependents’ land outside the city. The design continues the prototype from Stage 1 and integrates with the existing pedestrian system, allowing the circulation around the old city to unfold. Concrete pier walls are placed at the sections where the city wall disappears. The 2.4-meter modularity frames the city’s diversity within a series of vignettes, providing a repeated view of both the wilderness and the city.
Stage 3: “Archaeology”
As time passes, the newly constructed boundary becomes a relic of the past. The wooden structure is destroyed by weathering, and the remaining concrete pier walls bear traces of life, continuously performing the depth of time.
