场地背景和设计原型。EL 16.52是一家位于韩国釜山松岛近海的咖啡店。EL代表海平面以上的高度，16.52标志着建造主楼的地下楼层的海拔高度。其含义在于该遗址所属的国家地质公园的背景下，在建筑上隐含着这个地层的时间性，旨在包含在海平面以上的高度的含义中。这里的建设是为了在建筑原型的意义上解释地质公园、海洋和陆地之间的水平差异，并最终在商业上将其最大化。

Site context and design prototype. EL 16.52 is a coffee shop located off the coast of Songdo, Busan, South Korea. EL stands for altitude above sea level, and 16.52 signifies the altitude level of the underground floor where the main building was built. The meaning lies in the context of the National Geopark to which this site belongs is architecturally implied, and the temporal nature of this stratum is intended to be contained in the meaning of altitude above sea level. The construction here was to interpret the difference in level between geopark, sea, and land in the sense of architectural archetype and ultimately maximize it commercially.

停车流通的水平差异。该场地毗邻两条道路。一条是通往地下两层公共停车场的道路，另一条是通往松岛的两层地面道路。由于这两条道路的水平差约为13.5米，因此对土地形态的改变有相当大的限制。为了有效地利用如此有限的建筑面积，停车区被分成了两部分。这是因为与其用坡道连接上下两部分，不如将上下停车场分开，在它们之间放置调整好距离的机房，这样做是很有效率的。

Parking circulation for level difference. The site adjoins two roads. One is the road towards the lower public parking lot with two basement floors, and the other is towards Songdo with two ground floors. As these two roads had a level difference of about 13.5m, there were considerable restrictions on the change in land form. In order to efficiently utilize such a limited building area, the parking area was divided into two parts. This is because instead of connecting the upper and lower parts with ramps, it is efficient to separate the upper and lower parking and put the machine room with adjusted distance between them.

建筑面积根据土地的大小而定。有必要考虑咖啡馆面积的适当大小，超过法定标准的停车场数量，连接两条与土地接触的道路的运动系统，以及未来扩展的可能性。考虑到可以改变形状的土地的法定建设率，建筑的最大宽度约为15米。这也是创造项目商业可行性的最小尺寸，占车辆旋转半径的法定最低标准。上面两层楼很高，可以看到戏剧性的海景，由一个咖啡馆和一个天台组成。游客可以通过进入地面以上的二层与城市外围中心相连的主干道，进入上面的咖啡店

Building area according to the land size of the land. It was necessary to consider the appropriate size of the cafe area, the number of parking lots more than the legal standard, the movement system linking two roads in contact with the land, and the possibility of future expansion. Considering the legal construction rate of the land that can be changed in shape, the maximum width of the building was about 15m. It was also the minimum dimension to create the business feasibility of the project, accounting for the legal minimum standard for the radius of rotation of the vehicle. The upper two floors are high with a dramatic view of the sea and consist of a coffee shop along with a rooftop. Visitors can access the upper coffee shop by entering the second floor above the ground on the main road connected to the outer city center

拱门的配置和重复。建筑空间的基本形式是一个半圆形的拱门。圆形结构被切成两半，形成一个拱形框架，然后在结构上耦合和重复。半圆拱门是建筑逻辑的起点，也是创造整体建筑韵律的重要外部和结构元素。这种波浪式的结构被编织成约10米的结构柱，即第三层和第四层的高度，并形成一个三维结构。水平展开的波浪的重复与垂直的波浪在几何上相遇，多元的组合方式重复完成了建筑体系。在水平波浪与垂直支柱的交汇处形成了露台，形成了最大化的空间感。在考虑建筑的境界时，外墙采用了裸露的混凝土，为建筑的内部和外部装饰创造了一种体积的延续。

Configuration and repetition of arches. The basic form of building space is a semicircular arch. The circular structure is cut in half to form an arch frame, and then structurally coupled and repeated. The semicircular arch is the starting point of the construction logic and an important external and structural element that creates the overall architectural rhythm. This wave-like structure is woven into structural pillars of about 10m, the height of the third and fourth floors, and forms a three-dimensional structure. The repetition of horizontally unfolding waves meets the vertical waves geometrically, and the manifold combination method is repeated to complete the construction system. The terrace is formed at the point where the horizontal wave meets the vertical pillar to form a maximized sense of space. In considering the realm of construction, exposed concrete was used for the facade to create a voluminous continuation for the interior and exterior finishes of the building.
