The Place Costa Esmeralda is a private enterprise on the dunes of the Buenos Aires coast, located 390 km from Buenos Aires. It is a recent urbanization with a young afforestation of acacia trees and maritime pines and some sectors of consolidated forest. The site, with an extensive forty-five-meter front, belongs to the latter sector, so that the house had to incorporate this privileged landscape, while at the same time protecting its privacy towards the street. It was also necessary to consider that the dune it is part of has a slope of almost two meters overlooking the front and that, although its surroundings have a dense grove of trees, the land is only partially covered with species.

CostaEsmeralda是布宜诺斯艾利斯海岸沙丘上的私营企业，位于布宜诺斯艾利斯390公里处。这是一个最近的城市化，有一个年轻的绿树和海松的绿化，以及一些综合森林的部门。该网站拥有广泛的四十五米正面，属于后一部门，因此该房屋必须包含这一特权景观，同时保护其对街道的隐私。还必须考虑，沙丘是一个几乎两米的斜坡，可以俯瞰前面，虽然它的周围有茂密的树木，但土地只部分地被物种覆盖。

The Commission The commission was a house of no more than 150 sqm, with an aesthetic-constructive proposal similar to the other houses built in the area by the studio, valued according to the clients both for their spatial richness and for the low maintenance required. It had to have a generous meeting space, a visually integrated kitchen, two bedrooms (one with private bathroom) and an integrated living space to be used as an audio and video room and, eventually, as a guest bedroom. It should also have a grill and an expansion terrace.

委员会-是一栋面积不超过150平方米的房子，其美学建议类似于工作室在该地区建造的其他房屋，根据客户的空间丰富程度和所需的低维护程度，对其进行了估价。它必须有一个宽敞的会议空间、一个视觉上完整的厨房、两间卧室(一间有私人浴室)和一个综合的起居空间，以便用作音像室，并最终用作客人卧室。它还应该有一个烤架和一个扩建的露台。

The Proposal It was then decided that the different uses would be naturally accommodated on the slope of the land, distributed in three volumes that would simplify the procedure. These volumes are staggered with a difference of 45 cm between them, giving place in this displacement to the formation of small courtyards that incorporate the surrounding landscape. This first decision was the trigger for successive operations derived from it: the first one was the rotation of the floor plan in relation to the sides of the lot in order to coincide with its natural slope. Hence, the alignment of the main axis of the house with the north-south direction and, as a consequence of the latter, the need to resolve the project with well-differentiated façades: the east side exposed to the gaze from the street with very controlled openings, and the west side with large openings protected by vegetation. The northern end of the Forest Concrete House was designed as the culmination of the common space with a large semi-covered balcony protected from the views from the street by the local pastures and with distant views of great scenic value.

然后决定将不同用途自然地安置在土地的斜坡上，分成三卷，以简化程序。这些体积交错与45厘米之间的差异，让位于这种位移形成的小庭院，其中包括周围的景观。第一项决定是由此产生的连续作业的触发因素：第一项决定是将平面图相对于该地段的两侧进行轮换，以便与其自然坡度相吻合。因此，房子的主轴与南北方向成了一条线，而由于后者的原因，需要解决这个带有高差异外观的项目：东侧暴露在路旁的视线中，有非常受控的开口，而西侧则有由植被保护的大开口。森林混凝土屋的北端被设计为公共空间的顶点，有一个大的半覆盖阳台，不受当地牧场从街道上看到的风景的影响，而且远眺风景秀丽。

The Functional Organization The entrance was planned in the centre of the floor plan, i.e. at the midpoint of the slope and at the same level as the living/dining/kitchen area and the outdoor expansion. From there, a small flight of gently sloping stairs leads up to the most reserved area of the bedrooms, or descends to the living area to contemplate the landscape in front of the fireplace. The interior courtyards incorporate light, transparencies, reflections and vegetation into the rooms.

功能组织-入口处规划在平面图中心，即在斜坡中点，与居住/餐饮/厨房区域和室外扩建区相同。从那里，一小段缓缓倾斜的楼梯通向卧室中最保留的区域，或者下到起居室，观察壁炉前的风景。室内庭院包括光，透明，倒影和植被进入房间。

Structural Resolution and Construction Two unique materials: concrete and glass, were used to solve the integration with the landscape and to respond to the formal, structural, functional, finishing and maintenance issues. The structural solution adopted was to cover each volume with a slab that rests on inverted beams that are intertwined working together throughout the house. From these beams, the slabs extend into large cantilevers. The roofs between beams were designed as green terraces to increase the thermal insulation, as they receive sun during most of the day. The few hollow brick interior partitions are finished in painted, hardened plaster. The floor is made of cement smoothing cloths divided by aluminum planks. The openings are made of dark bronze anodized aluminum. The heating system, since there is no natural gas in the area, was solved with an electric under-floor heating system.

结构解析和施工两种独特的材料：混凝土和玻璃，被用来解决与景观的整合，并对形式、结构、功能、修整和维护等问题做出反应。采用的结构解决方案是用倒梁覆盖每一体积的板，这些横梁相互交织在一起，在整个房子里一起工作。从这些梁中，板延伸成大悬臂。梁之间的屋顶被设计成绿色的梯田，以增加隔热性能，因为它们在一天的大部分时间里都会受到阳光的照射。少数空心砖内部隔墙是用油漆，硬化灰泥完成的。地板由水泥平滑布和铝板隔开而成。开口由暗青铜阳极氧化铝制成。由于该地区没有天然气，采暖系统采用地下电热系统解决。

Furniture Except for the beds, sofas and chairs, the rest of the equipment of this house is made of concrete.

除了床、沙发和椅子之外，这所房子的其他设备都是用水泥做的。
