罗马北区的ONTO Álvaro Obregón项目位于阿尔瓦罗·奥夫雷贡街（Álvaro Obregón），介于Frontera街与Mérida街之间。该区域以本地居民与外国居民混合共居，以及活跃的城市社交生活而闻名。项目的建筑概念是一座结合出售与出租单元的复合建筑，其中出租部分采用酒店式运营模式：投资者购买客房，并授权物业所有者Grupo ONTO统一管理租赁业务。项目旨在为希望在墨西哥城核心区域进行短期或中期居住的国内外旅客提供完整的生活体验。

The ONTO Álvaro Obregón project is located in the Roma Norte neighborhood of Mexico City, on Álvaro Obregón Street, between Frontera and Mérida. This area is known for its mix of locals and foreigners, as well as its vibrant social life. The architectural concept consists of a building that combines units for sale and rent, the latter under a hotel-style scheme in which investors purchase rooms and allow Grupo ONTO, owners of the property, to manage the rentals. It offers a complete experience for both foreign and national tourists seeking to live in the heart of Mexico City for short or medium stays.

该项目通过混合结构体系实现了空间效率的优化：将预制木结构与钢构件结合，形成双层立面系统，并由梁结构支撑。这些梁与混凝土柱及桩基础连接，在降低环境影响的同时保证建筑的耐久性。由外露木结构构成的网格状双层立面，从外部便可清晰呈现建筑的功能组织，模块化客房也由内部显现出来。该结构同时作为环境过滤系统，控制日照并促进交叉通风，从而营造舒适的室内环境。

It is a complex that optimizes space through a hybrid structure, combining prefabricated wood with steel elements in a double façade, supported by a beam structure. These beams are connected to concrete columns and pile foundations, reducing environmental impact while ensuring the building’s durability. The grid-like double façade, composed of an exposed wooden structure, reveals the function of the building from the outside, with modular rooms visible from within. This structure is also designed to act as a filter, controlling sunlight and allowing cross-ventilation, thus contributing to a comfortable indoor environment.

由于场地土壤承载力较低，项目进行了详细的岩土研究，以确定最适合的基础策略，包括桩基与承台系统，以均匀分配建筑荷载。其中一个主要挑战在于确保木结构拥有足够强度，使其在与混凝土柱、墙体及楼板结合后，仍能够形成具有宽敞尺度与较高层高的空间。最终形成的节点细部兼顾美学与功能，通过隐藏式钢连接件实现木结构与混凝土之间的连接，使立面呈现出仿佛由整块木板直接堆叠而成的纯净效果。

Due to the low soil consistency, detailed geotechnical studies were carried out to determine the most suitable foundation strategy, which includes piles and footings that evenly distribute the load. One of the main challenges was ensuring that the wooden structure had sufficient strength so that, when combined with concrete columns, walls, and slabs, it could create spacious areas with generous ceiling heights. The resulting joints blend aesthetics and functionality, using concealed steel connectors between the wood and concrete, producing a clean façade that appears as if solid wooden planks were simply stacked together.

项目通过退让街道界面的方式回应城市环境，在建筑与繁忙的阿尔瓦罗·奥夫雷贡大道之间创造出一道植被缓冲带，以部分隔绝罗马区核心区域的噪音干扰。位于街道层面的绿化区域形成一条类似门厅走廊的过渡空间，引导人们进入建筑内部。位于首层的Rufus餐厅则将建筑与街区日常生活联系起来，同时促进当地经济与居民生活品质的提升。

The project responds to its urban context by setting back the façade to create a buffer of vegetation that partially insulates users from the noise of bustling Álvaro Obregón Avenue, the heart of Roma. This green area at street level forms a hallway-like lobby leading to the building’s entrance. The restaurant Rufus, located on the ground floor, connects the building to the neighborhood’s daily life, benefiting both the local economy and residents’ quality of life.

建筑被划分为两座塔楼：一座面向主街，另一座朝向后方的内部花园。两者通过体量侧边挤出的两个半圆形体加以区分并相互连接。由此形成的空隙空间被设计为地下层庭院，铺设碎石地面，并配置整体式混凝土座椅及丰富植被，包括蕨类、苏铁与肯氏棕等植物。这些沉思与休憩空间，随着垂直花园层层向上延展而愈发鲜明，营造出一种绿意一路生长至屋顶的感受，陪伴使用者穿行于建筑的每一层。与之相辅相成的是贯通至屋顶的中央通风井，它不仅强化自然通风，也将自然光引入所有楼层，进一步提升整体空间体验。围绕这一理念，楼梯被塑造为具有雕塑感的空间元素，使人们在被自然植被包围的环境中，获得更具层次感的垂直动线体验。同样，公寓的通风系统也借由这一布局，将卫生间开口设置于中央竖井之中，并通过由回收铁路枕木制成的狭长窗洞加以隐藏。

The building is divided into two towers—one facing the main avenue and the other overlooking a rear interior garden. These are distinguished and connected by the extrusion of two half circles along the sides of the volume.The resulting voids are designed to form patios at basement level, featuring gravel flooring, monolithic concrete benches, and lush vegetation including ferns, sago palms, and kentias. These spaces of reflection and rest grow stronger with each level thanks to vertical gardens, creating the sensation that they extend all the way to the rooftop, accompanying users on every floor. This design decision is complemented by a central ventilation shaft, which also reaches the roof and allows natural light to illuminate all floors, enhancing the user experience throughout the building.Supporting this idea, the staircases become a sculptural statement, enhancing the spatial journey on each level surrounded by natural foliage. Similarly, the apartment ventilation system uses this layout to position bathroom openings within these central shafts, discreetly hidden by narrow windows made from repurposed railroad ties.

建筑共包含八层住宅空间：地上七层与地下一层，其中地下层的房间可直接通往后部花园。每层设有八个单元，均包含卧室、起居室、餐区、小厨房、书桌区、卫生间以及小型阳台。顶层则设置为面向公众开放的屋顶花园，可眺望墨西哥城最佳景观，并配备酒吧与露天用餐区，鼓励住户与外来访客之间的交流互动。如前所述，植被贯穿整个项目，并一直延伸至屋顶。景观设计由Hugo Sánchez操刀，他选择了大量低维护、枝叶繁茂的本土植物。

The architectural program includes eight levels of housing: seven above street level and one basement level, featuring rooms with access to the rear garden. Each level contains eight units, each with a bedroom, living room, dining area, kitchenette, desk space, bathroom, and a small balcony. The top level features a public rooftop garden that frames the best views of Mexico City. It includes a bar and open-air dining area designed to foster interaction between residents and outside guests. As mentioned, the project is accompanied throughout by vegetation, even up to the rooftop. This landscape design was created by Hugo Sánchez, who selected low-maintenance native plants with abundant foliage.

项目采用雨水收集系统作为可持续策略之一，在降低住户运营成本的同时，也倡导更加负责任的水资源使用方式。整体空间氛围力求克制而温暖，大堂与屋顶花园等公共区域大量运用天然木材与花岗岩打造固定及可移动家具，并辅以精心布置的绿植。客房内部则以木梁与木楼板为基础，搭配Caledonian花岗岩、Chukum灰泥墙面以及本地织物等天然材料。由M:A工作室负责的室内设计，在保证易维护性的同时，也实现了与周边环境的自然融合，营造出温暖宜居的生活空间，提升居住者的生活品质。

The project incorporates a rainwater harvesting system as a sustainable strategy, reducing tenant expenses and promoting more responsible water use. The project’s atmosphere seeks to be sober and warm, with public areas like the lobby and rooftop garden featuring natural wood and granite in both fixed and movable furniture, always accompanied by strategically placed greenery. Room finishes complement the wood beams and slabs with natural stone materials such as Caledonian granite, chukum-style plastered walls, and locally sourced textiles used in the furniture. This interior design, by studio M:A, ensures ease of maintenance and seamless integration into the surrounding context, creating warm, livable spaces that enhance the residents’ quality of life.

每个公寓阳台上均种植了番石榴树与橄榄树，在丰富景观层次的同时，也让居者始终与自然保持联系。项目希望营造一种与城市快节奏形成对比的生活状态，使居住者能够从都市喧嚣中暂时抽离。事务所一贯的设计方法强调节奏感与对称性，关注室内与室外、结构与立面的整体融合，并始终重视景观设计的作用。

Guava and olive trees are incorporated into each apartment balcony, elevating the views and maintaining constant contact with nature. The intent is for life within the project to contrast with the city’s hectic pace, allowing residents to disconnect from urban chaos. The studio’s signature approach is defined by a consistent rhythm and symmetry, integration of interior and exterior, structure and façade, and a strong focus on landscape design.

本项目正是这些理念的体现：以清晰有序的几何构成，建立建筑与自然及城市环境之间的紧密联系。网格化立面与虚实关系的处理成为设计中极具辨识度的元素，为建筑带来秩序感与整体性。对事务所而言，最有价值的是完成了一座能够积极回应周边环境、改善城市形象的建筑，同时也借由新材料的尝试，实现了一次成功的实践。从外立面延续至室内空间的木结构系统，不仅是一次充满挑战的创新探索，也为可持续、高效的建造方式提供了新的可能。最终呈现的是一座不仅满足居住功能，更丰富城市景观、并通过促进人与人之间的联系与社区互动，为使用者带来独特体验的建筑。

This project reflects those principles by combining clear, orderly geometry with a strong connection to nature and the urban environment. The grid-like façade and play of voids are distinctive elements that add coherence and clarity to the design. What the firm finds most rewarding is having designed a building that contributes positively to its surroundings, improving the city’s image while experimenting with new materials to deliver a successful project. The opportunity to innovate with a wooden structure visible from the exterior all the way into interior spaces represented both an exciting challenge and a chance to explore sustainable and efficient construction solutions.The result is a building that not only fulfills its role as housing but also enriches the urban landscape and provides a unique experience for its users by encouraging connection and community among visitors.
