Appreciation towards RAS Arquitectura for providing the following description:


The proposal is for a small budget intervention in which demolition is minimized to make the most of existing features, aimed at combining a second home with seasonal rentals. However, the home’s current floor plan is outdated and does not meet the new functional requirements and needs.

通过一些细微的变化,建筑师试图改变住宅被使用的方式。原来位于一楼的厨房空间很小,而且和其他空间也没有任何联系;新的厨房在保持原有位置的情况下变为了开敞式的空间,这样既可以拓展空间感,也可以避免改动现有的管道和排水系统。原有的承重墙亟待重新整修,建筑师在加固结构下方打破了原有的实墙,加入一个弯曲的隔板,创造出新的用餐区。这个隔板只有 180 厘米高,定义功能的同时保持了空间的连续性。

With a few changes, the idea is to change the way the house is lived in. On the ground floor, the kitchen is small and has little relation to the other spaces; although the new kitchen project maintains its current location to take advantage of the existing plumbing and drain systems, it now opens up to the living room through an opening in the wall that separates these two spaces, which is a load-bearing wall and thus requires reinforcing. Under this reinforcement, a new curved partition is added between the living room and the kitchen, creating a dining area. But this partition does not reach the ceiling as it is only 180 cm tall, and its purpose is to create a distinct area but without splitting the space, adding interior circulation complexity and spatial richness. The rest of the interior interventions on the ground floor are focused on creating a space continuum without physical separation but using specific elements to define the different areas based on their function.

On the first floor, again with the aim of preserving most elements and minimizing demolition, the five-bedroom layout is kept, but the features of the central bedroom are completely changed: its opaque doorway becomes transparent, with the possibility of opening this room completely to the hallway through two large sliding doors. This way, this room’s function becomes flexible, as it can be separated from the rest as a bedroom (by means of an opaque curtain), as a game or reading room, or as the extension of the hallway into the outdoor terrace. Concealed built-in closets hide folding beds and storage surfaces, enabling different uses for these rooms. Replacing the floors, as well as the new wall lining, helps reinforce this new strategy.

For the ground floor, a new black ceramic floor in a herringbone pattern unifying all areas and seen again in the common areas on the first floor is selected. The intervention on the ground floor (daytime living areas) and the first floor (nighttime living areas) can be read as a dialectical play: on the ground floor, the spaces are physically connected but visually and functionally separated, while on the first floor, the main room is visually connected but physically separated.
