AMASA Estudio：自20世纪中叶以来，墨西哥城通过综合住宅体的开发，形成了坚实的集体住房建设传统。如今，墨西哥城约有一万座住宅综合体，近一半的城市人口居住在这样的公寓式住宅中，这些多户住宅项目共享城市基础设施、公共空间、管理服务，以及邮政编码。其中，近三分之一由 INFONAVIT（国家劳动者住房基金研究所）建造，该机构负责为工人提供住房。
在距首个多户住宅项目建成 75 多年后的今天，由于缺乏维护和政府忽视而引发的相关问题日益显现。然而，尽管在全国范围内的基础设施和服务投入巨大的公共投资，但墨西哥城及其大都会区的住宅综合体长期以来仍被忽视，直到最近情况才有所改观。
AMASA Estudio：Since the mid-20th century, Mexico City has developed a strong tradition of collective housing construction through the development of residential complexes. Today, nearly half of the city’s population lives in condominium-style housing. The city has approximately ten thousand housing complexes—multifamily developments that share urban infrastructure, communal spaces, management services, and even postal codes. Of these, nearly one-third were built by INFONAVIT (Instituto del Fondo Nacional de la Vivienda para los Trabajadores), the state agency responsible for housing for workers.
Now, more than 75 years after the first multifamily housing project was built, issues stemming from a lack of maintenance and government neglect have become increasingly evident. However, despite significant public investment in infrastructure and services across the country, housing complexes in Mexico City and its metropolitan area had remained largely overlooked—until recently.
该项目由Andrea López和Agustín Pereyra （AMASA Estudio）领导，专注于在墨西哥城四个最具代表性的INFONAVIT住宅综合体——伊斯塔卡尔科Iztacalco、圣塔菲Santa Fe、库尔瓦坎Culhuacán El Rosario和伊格纳西奥·查韦斯Ignacio Chávez的公共空间实施全面改善策略。由于时间和预算的限制，这四个初步设计在通过 INFONAVIT 组织的竞赛获得批准后的两个月便完成了。评估标准不仅考虑了干预措施的设计，还考虑了干预措施的可行性、管理和成本效益。
The project, developed by Andrea López and Agustín Pereyra (AMASA Estudio), focused on a comprehensive improvement strategy implemented within the communal areas of four of INFONAVIT’s most representative housing complexes in Mexico City: Iztacalco, Santa Fe, Culhuacán, and Ignacio Chávez. Given time and budget constraints, the four preliminary designs were developed in less than two months after being awarded through a competition organized by INFONAVIT. The evaluation criteria considered not only the design of the interventions but also their feasibility, management, and cost-efficiency.

AMASA Estudio项目的成功的关键主要在两个方面：首先，设计师对场地进行了深入分析，为其设计了四个量身定制的社区改善方案，同时在有限的预算下高效进行。其次，项目的管理模式尤为出色，需要AMASA Estudio与施工单位和项目管理团队之间紧密合作，这种协调合作成功地吸引了多个政府机构，包括INFONAVIT、社会检察办公室（Procuraduría Social）、地方政府，以及最重要的居民委员会。这些委员会通过社区参与过程积极参与，确保干预措施具有参与性、有效性和可复制性。
这些项目面临的最大挑战之一是：如何在复杂的在公共空间内展开施工，这些空间虽在功能上是公共空间，但在法律上属于私人财产。这种“无主之地”状况，即土地权属和法规体系交汇，对干预措施的成功起到了决定性作用。
The success of AMASA Estudio’s work lies in two key aspects. First, the strategy involved an in-depth site analysis, leading to the development of four tailored neighborhood improvement projects, each responding to its specific conditions while working within limited budgets. Second, the project’s management was particularly noteworthy, requiring collaboration between AMASA Estudio, the construction firm, and the project management team. This coordination successfully engaged multiple government agencies—including INFONAVIT, the Social Prosecutor’s Office (Procuraduría Social), local governments, and, most importantly, the residents’ committees. These committees were actively involved through neighborhood engagement processes, ensuring that the interventions were participatory, effective, and replicable.
One of the greatest challenges of these projects was navigating the complexities of working within communal spaces—areas that function as public spaces but are legally private property. This “no man’s land” scenario, where land tenure and regulatory frameworks intersect, played a crucial role in determining the success of the interventions.
UH INFONAVIT Iztacalco 住宅综合体是该机构于1972年建造的首个住房项目，它位于墨西哥城东部的伊斯塔卡尔科（Iztacalco），已有700年的历史。最初，住宅围绕一个人工湖展开，然而，1979 年地震造成的土壤裂缝影响了湖泊的稳定性，导致其被排空。25年后，市政府将该场地改造成现在的“湖泊公园”（Parque del Lago），其中心结构由混凝土柱支撑一个半球形钢框架，占地约500平方米。由于施工缺陷，结构的不规则几何形态导致部分区域的结构完整性受到影响，使得穹顶未能完成。随着时间的推移，该场地逐渐被废弃，混凝土平台和裸露的钢框架在风雨侵蚀下荒废了20多年。
The UH INFONAVIT Iztacalco Complex was the first housing development built by the institute in 1972. Located in Iztacalco, in the eastern sector of Mexico City—an area that celebrates 700 years since its founding—it originally centered around an artificial lake. However, after the 1979 earthquake, soil fissures compromised the lake, leading to its drainage. Twenty-five years later, the city government transformed the site into what is now “Parque del Lago”, featuring a central structure composed of concrete columns supporting a semi-spherical steel framework spanning approximately 500 m². Due to construction deficiencies, the irregular geometry of the structure resulted in sections that compromised its structural integrity, leaving the dome incomplete. Over time, the site was abandoned, and both the concrete platform and the exposed steel framework deteriorated under the elements for two decades.

2024年，INFONAVIT发起了一项公开竞赛，征集关于该住宅综合体中心公共区域的设计、管理和干预方案。其中最具挑战性的要求之一是封闭半球结构，以保护其下方空间并提供遮风挡雨的功能需求。
AMASA Estudio团队在赢得竞赛后，开启了复杂的协调过程，涉及多个政府机构。经过约 800 万比索的投资和四个月的施工——这一过程展现了高效的资源管理能力——如今该半球结构已拥有完整的屋顶。此外，UH INFONAVIT Iztacalco 住宅综合体的核心区也通过景观、色彩和结构干预得以焕新。新的公共空间包括一个 260 平方米的遮蔽活动广场、为人们提供社交和休闲座椅、专门的跑酷区域，以及备受欢迎的街头健身区。
In 2024, INFONAVIT launched an open-call competition for a design, management, and intervention proposal aimed at revitalizing the central common area of the housing complex. One of the most challenging requirements was to enclose the semi-sphere to protect the space beneath from sun and rain.
Upon winning the competition, the team initiated a complex coordination process involving multiple government agencies. After an investment of approximately eight million pesos and four months of construction—a testament to the project’s efficient resource management—the semi-sphere now has a functional roof. Additionally, the heart of the UH INFONAVIT Iztacalco Complex has been revitalized with landscape, chromatic, and tectonic interventions. The new public space includes a 260 m² covered forum, tables for socializing and relaxation, a designated parkour area, and a popular calisthenics workout zone.

在这些新增的活动中心，12米高的半球结构成为战略性新屋顶系统的焦点，旨在为社区聚会提供遮阳功能。干预措施还采用了对色彩的敏感处理，鲜艳的色调与此前主导的灰色混凝土形成对比。新的论坛和强化的穹顶结构采用暖色调的颜料混凝土，而绿松石色钢结构支撑着波纹金属面板，以富有动感的多色饰面呈现。
At the center of these new activities, the 12-meter-high semi-sphere became the focal point for a strategic new roofing system, designed to provide enhanced shade for community gatherings. The intervention also integrates a sensitive approach to color, with vibrant hues contrasting against the previously dominant gray concrete. The new forum and reinforced dome structure feature pigmented concrete in warm tones, while turquoise-green steel structures support corrugated metal panels in a dynamic, polychromatic finish.
为解决竞赛提出的封闭半球结构的要求，该方案在柱基和钢连接处实施了结构加固。悬挂式斜屋顶系统由钢格架和轻质金属板组成，并通过高强度钢缆固定。这一解决方案优化了资源，以最少的材料覆盖最大面积，成功满足了 INFONAVIT 的目标，同时提升了场地的建筑特色。
To address the competition’s requirement of covering the semi-sphere, the proposal included structural reinforcements at the column bases and steel joints. A suspended, inclined roof system—formed by a steel grid and lightweight metal sheets—was secured with tensile steel cables. This solution optimized resources by covering the space with minimal material yet maximum impact, successfully meeting INFONAVIT’s objectives while enhancing the site’s architectural character.
该项目展示了墨西哥城住宅综合体公共投资的变革潜力。经过精心设计的干预措施，以资源效益和战略规划为基础，让公共区域焕然一新——将其打造为社区聚会、休闲、学习和社交互动的空间。这些改善为居民提供了锻炼和邻里互动的机会，增强了人们的归属感和社会凝聚力。最终，该项目也证明了，巨额的预算并非成功的必要条件，至关重要的是精心规划、良好管理和合理设计，以此赋予公共空间新的生命，并加强墨西哥城住宅社区的社会纽带。
This project exemplifies the transformative potential of public investment in Mexico City’s housing complexes. Thoughtfully designed interventions, rooted in resource efficiency and strategic planning, can revitalize common areas—turning them into spaces for gathering, recreation, learning, and community engagement. These improvements provide residents with opportunities for exercise and neighborhood interaction, fostering a sense of belonging and social cohesion. Ultimately, this project demonstrates that large budgets are not always necessary—what matters most is a well-planned, well-managed, and well-designed public investment strategy that breathes new life into communal spaces and strengthens the social fabric of Mexico City’s housing communities.
