架构师提供的文本描述。西尔维纳和奥马尔的房子曾经是布宜诺斯艾利斯大都会地区典型的当地模式之一。静默的城市插入，简单而紧凑的布局在其单一的水平，释放出部分地段后，一个平面屋顶直接相关的顶部邻近的树木和茂密的植被在后面。

Text description provided by the architects. Silvina and Omar's house used to be one among the typical vernacular models in the metropolitan area of Buenos Aires. Silent as to its urban insertion, simple and compact in its layout on a single level, releasing a portion of the lot to the back, a flat roof directly related to the tops of the neighboring trees and dense vegetation at the back.

时间的自然衰退和生活方式观念的改变，加上需要在物业内增加一个出租单位，鼓励业主委托进行一项工程。

The natural decay of time and a change in the conception of the way of living, coupled with the need to add a rental unit to the property, encouraged the owners to commission a project.

考虑到现有建筑所表达的需求和价值属性，新房不仅在功能上，而且在管理和能源消耗方面，以及在客户本身的经济性方面，都是对现有房屋的补充。

Considering the expressed needs and the attributes to value from the existing construction, the new house is formulated as a complement to the existing house, not only in functional terms, but also in terms of its management and energy consumption, and the very economy of the client.

底层最低限度的干预措施让位于开放的视角，恢复了对狭小和角落表面的使用。对空间的最佳利用导致了最初与平顶相结合的干预，这支持了新房子，新房子使用了前车库的一部分来定位其出入楼梯，并将其布置在底层的屋顶上。所选择的施工系统重量轻，以免危及基础结构的稳定性。屋顶的排水沟可以回收雨水。该程序的分布被组织成三片，构成一个向街道的相关梯度，通过一系列小开口到达后立面，这些小开口上生长着原始的植被，从而确保了楼下花园的隐私，并根据季节的需要有效地通过了光线。除了水回收系统外，新的部分还为两个住房单元提供了太阳能热预热系统，并大大提高了第一套房屋的热力效率。

Minimal interventions on the ground floor gave way to open perspectives, recovering the use of small and cornered surfaces. The optimal use of space that led to the initial intervention in conjunction with the flat roof supported the new house, which uses a portion of the former garage to position its access staircase, and is laid out across the roof of the ground floor. The chosen construction system is lightweight, so as not to risk the structural stability of the base. The roofs are in a gutter that allows to recover rainwater. The distribution of the program is organized into three slices that make up a relational gradient towards the street, reaching the back facade with a series of small openings over which the original vegetation grows, thereby ensuring the privacy of the garden downstairs and an efficient passage of light according to seasonal needs. In addition to the water recovery system, the new piece provides a solar thermal preheating system for both housing units, and considerably improves the thermodynamic efficiency of the first house.

Each one recognizes its attributes on the other, they are shared and improved without pretending to resemble each other too much or too little.
