台灣地處地震帶，都市地區老舊窳陋建築林立，潛在災防風險極高。為加速都市危險及老舊建築物之重建，政府於民國 106 年公布實施《都市危險及老舊建築物加速重建條例》（簡稱《危老條例》）。然而，該條例要求「100%全體同意」之嚴格門檻，導致實務上多數成功案例皆流於微型基地之「牙籤屋」，極少有大面積且具備宏觀都市景觀效益之指標個案。 本研究以全台灣核准首例且具備大基地規模之危老重建案為核心實證對象，其基地面積為3，113 m2，涉及 40 筆地號。本研究採取個案研究法（Case Study），結合官方評定書與重建計畫之文本分析，並對建設公司、建築師及第三方專業機構進行深度訪談。 研究結果顯示，本案之所以能在複雜的多產權老舊社區中，突破傳統都市更新曠日廢時的博弈僵局，迅速達成 100% 全體同意，關鍵在於兩大執行策略：第一，實施者採取「一價到底、極致透明」的誠信溝通模式，消弭地主間的資訊不對稱與預期心理；第二，積極導入「不動產開發信託」與建經公司之工程專案管理，以第三方防險機制解除地主對爛尾樓的道德風險恐懼。 在效益實證方面，本案鎖定當時政府推動下最高 40%之容積獎勵，並以高規格之 SRC 構造，成功取得國家「耐震標章」、「銀級綠建築」及「無障礙二級環境」之多重認證；同時透過臨路大膽退縮 4 m留設林蔭步道。本案實證危老重建在健全的民間機制與良善的企業規劃下，不僅能活化私有資產價值，更能將政策誘因實質轉化為環境永續、高齡友善與都市防災等龐大的公共利益，作為危老條例推動下的範例之一。;Taiwan is located in an active seismic zone with a high density of aging and dilapidated buildings in urban areas， posing significant potential disaster risks. To accelerate the reconstruction of urban unsafe and old buildings， the government promulgated the "Statute for Accelerating Reconstruction of Urban Unsafe and Old Buildings" (hereinafter referred to as the "Statute") in 2017. However， the strict requirement of 100% consent from all property owners has led to a prevalence of micro-scale "toothpick houses" in practice， with very few large-scale benchmark cases yielding macro-urban landscape benefits. This study focuses on the "Xin-Pu-Zhan" project in Banqiao (with a total site area of 3，113 m2 involving 40 plots of land)， which is the first approved large-scale reconstruction case in Taiwan. Adopting a case study methodology， this research combines document analysis of official evaluation reports and reconstruction plans with in-depth interviews with the developer (Tan Shi Construction)， architects， and a third-party professional institution (Chiao Fu Building Management). The research findings indicate that the project successfully overcame the game-theoretic deadlock of traditional urban renewal and rapidly achieved 100% consent in a complex multi-ownership old community due to two core execution strategies. First， the developer adopted a "highly transparent and uniform distribution" communication model， eliminating information asymmetry and speculative psychological expectations among landowners. Second， the introduction of the "， Real Estate Asset Trust" and professional project management by the building management company effectively removed landowners′ moral hazard fears regarding incomplete construction. In terms of benefit verification， the project precisely secured the maximum 40% floor area bonus and successfully achieved multiple certifications， including the national "Seismic Mark，" "Silver-grade Green Building，" and "Level 2 Barrier-Free Environment" with a high-spec SRC structure. Additionally， a 4-meter setback was voluntarily created to provide a shaded pedestrian walkway. This project proves that， under sound private mechanisms and proactive corporate planning， the reconstruction of unsafe and old buildings can not only activate private asset values but also substantively transform policy incentives into immense public benefits such as environmental sustainability， elderly-friendliness， and urban disaster prevention. It serves as a textbook paradigm for urban regeneration in Taiwan.
