Casa CH73项目旨在利用该地区的法规，以一种可持续发展的视角，将限制转化为契机，创造一座独特住宅。这种方法打破了该地区常规的建筑模式，通常，建筑通过混凝土平台将雨水排入市政系统，这减少了水对底层土壤的渗透，对该地区原有的动植物群带来负面影响。

The project for Casa CH73 aimed to transform the area's regulations into an opportunity to create a unique residence from a sustainable perspective. An approach that broke the construction paradigms imposed in the area, with concrete platforms that drain rainwater into the municipal system, diminishing water infiltration into the subsoil and destroying the original flora and fauna of the site.

项目总面积为1023平方米。一方面，由于项目东侧与联邦保护区接壤，建筑设计遵守了相关法规，即必须在建筑周边留出5米的退让距离。另一方面，由于已有挡土墙的存在，建筑一半的面积将处在低于路面30米的高度。这些条件使得房屋被设计为一个坐落于优美景色之间的悬臂结构，服务空间和使用空间划分明确。

Casa CH73 occupies a total surface area of 1,023 square meters. Its architectural design arises, on the one hand, from adherence to regulations, which necessitates respecting a 5-meter perimeter around the property when bordering a federal reserve to the east. On the other hand, the preexistence of a retaining wall, leaving half of the property 30 meters below the roadway, led to the conceptualization of the house as a cantilevered structure, surrounded by interesting views and featuring a clear division between the served and serving spaces.

结构设计以钢结构框架在斜坡的坡顶悬挑出20米，充分利用了整个地块的长度。钢结构由三面混凝土承重墙支撑，地下室由用于发电的地热桩锚固。

The structural design is resolved through a steel framework that extends 20 meters over the slope, fully utilizing the entire length of the plot. The steel structure is supported by three concrete load-bearing walls, composing the basement anchored by geothermal piles used to generate electricity.

这些地热桩和太阳能电池板一起帮助房屋内进行气候控制，并在热泵的支持下为泳池预热。

These piles and the solar panels contribute to climate control in the house and preheating the pool for the rest of the year with the support of a heat pump.

在水资源管理方面，项目设置了一个生物发酵池系统来处理废水，处理后的水可用于联邦区的灌溉，雨水则被引入地下，以改善林地现在的糟糕状况。

Regarding water management, a biodigester system was installed to treat wastewater for irrigation in the federal zone, and rainwater is directed underground to improve the conditions of the mistreated wooded area.

住宅的立面兼具围护和通风作用，在室内营造出一个光线充足、空气自然流通、视野可将峡谷一览无余的起居环境。空间布局灵活多变，可轻松适应变化或客户需求。

At the interior, the residence features protected and ventilated facades, creating an environment surrounded by light and natural air, with open views towards the canyons. The spaces are flexible and can easily adapt to changes or client needs.

项目将景观种植作为当地植树造林工作的一部分，因而采用了当地特有的植物种类（如醉鱼草、蒙特苏马松和牛油果树），以及其他原本在场地上自然生长的树种。

As part of the reforestation efforts, it was decided to plant endemic species such as tepozán, ocote, and avocado trees, specific to the fauna, along with other species that had naturally grown on the pre-existing platform of the property.

这些设计策略结合起来，使得项目实现了净零排放，这意味着住宅可以依靠在地生产的能源满足全部电力需求，还可以通过收集和循环利用水资源减少消耗。

All these design strategies allowed us to achieve a Net-Zero factor, meaning the residence can produce the entirety of its electrical energy, in addition to recycling and capturing water to reduce its consumption.
