Architecture as Space, Architecture as Product – There are two major attitudes towards ‘executing architecture’: designing architecture as space and designing architecture as a product. Many architects and studios in the schools emphasize ‘architecture as space’. Taking the proverb, ‘the use of the bowl is in its void’, for example, they tend to denigrate morphism and functionalist architecture in favor of a ‘sense of place and atmosphere that is often difficult to define. However, these two attitudes are not superior, opposite, or incompatible. Those who speak of architecture as space place their weight on history, memory, tradition, context, place, and so on, and those who design architecture as a product concentrate on function, performance, form, material, technology, tectonics, and details. The architecture of the former is usually studied through perspective drawings, and the hand sketches of the architect, and the latter is usually expressed through bird’s-eye views, isometrics, and exploded drawings. Of course, the former is more interested in sensitivity and the artistic, and the latter is more interested in reason, technology, and the scientific.
Throughout the era of modern architects, there was an enthusiasm for new machinery and the advancement of capitalism, whereas now Korean architecture seems to talk about space but, it is often focused on the product or commodity. The modern-style buildings in a prestigious architecture magazine also boast the concept behind each, but this is like an iPhone, Galaxy, Huawei, or Xiaomi phone displayed in a store showcase as different brands. When it comes to commercialization, it is not easy to be distinctive because they are required to be fashionable, designed and built at a faster and faster pace, and constructed to achieve maximum performance at minimum cost. The situation at the time of designing the Gwanak Arboretum Education & Management Building constituted of a client-less, short design period, an insufficient construction budget, and the complicated selection of the contractor was hard to figure out due to the blind bid by Public Procurement Service, which was not different from that stated above. The biggest idea that arose during the design phase of this building was that it should not be architecture that is biased towards only the creation of either a space or a product. Therefore, in order to devise architecture as a spatial experience, the reinterpretation of Korean traditional architecture was adopted, and digital design and fabrication were used to cope with the sense of architecture as a product.
The Art of Architecture – As a historical record, architecture should not only partake in the mainstream culture of its time but also identify with advanced technology. Two kinds of technology are usually used in the realization of a building: design technology and construction technology. Architects should select design technologies with construction technologies in mind. More recently, in terms of architectural production, the maximum amount of factory fabrication is increasingly required along with the minimum amount of on-site construction for ‘architecture as product’. Since the Gwanak Arboretum Education & Management Building was in a heavily wooded mountain area, rather than in an urban context, lean construction, which minimizes on-site construction, was considered one of the important factors from the beginning. For this purpose, instead of a reinforced concrete structure, which requires a lot of construction equipment on the field, they adopted a lumber structure, which was the inevitable decision to match the status of a building for the study and cultivation of plants and trees.
In designing this lumber structure building, numerous formative studies had to be executed to realize the natural curved roof line resembling the Gwanak Mountain ridge. We used a parametric design modeling technique with a Grasshopper plug-in, primarily because it is almost impossible to study an atypically shaped lumber structure building consisting of various types and sizes of elements only with 2D drawings and physical models. For the four-roof structure, approximately 40 variables were assigned to each roof, and hundreds of roofs were tested by varying their values over a short period of time. In addition, we developed the logic that automatically generates the structural frame, its connective detailing, and a list of elements as soon as the shape of the roof has been determined. At the design stage, not only the design work but also various other matters required for construction were determined in advance through virtual simulations, so that it would be possible to reduce a significant amount of trial and error, production time, and cost. This shows how we have reached a point in which the virtual world and reality interact and can be reflected in the design process of this building.
An Infinite Duality: Unit & Field – Another central idea of designing the building was the concept of the ‘Unit’ and ‘Field’. A unit is a physical and metaphysical element, like a quantum or particle, that constitutes the micro world, but in this context occurs when an individual work of architecture is disassembled. On the other hand, the field refers to a big idea, including the relationship, holistic formation, and global geometry that establishes a macro world. The former is associated with the grid, the unit, an element, and unit space, and the latter corresponds to an ideal, a symbol, a narrative, and a context. You can start with a unit and populate a space to build a system. On the contrary, you can decide upon a huge relational framework first and fill it with small units. This is what modern physics has revealed when pondering and reflecting upon the structure of the universe and the meaning of life.
In order to create an architecture that is more harmonious with the very Korean nature of Gwanak Mountain, we borrowed a spatial composition from traditional Korean architecture – a temple or seowon – located in a similar environment. The Gwanak Arboretum Education & Management Building begins with a unit of spatial composition called a ‘toi’, ‘kan’ made by the members of the lumber structure unit. These units are gathered to form ‘che’, and how ‘che’ accumulate to make a building is a strategy that can be easily adapted to a local context by resonating with the concept of the ‘Unit’ and ‘Field’. After completion, this approach exposes a great many limitations for several reasons, and although it is not revealed exactly as it is written above, the SNU Gwanak Arboretum Education & Management Building is trying to be an end to or the beginning of the more negative aspects of our epoch, like the word of Kafka projected into a harsh Korean situation. It is an effort to embody the universality of the world, and furthermore the universe, as it is a space that has inherited a sense of tradition, but it is also a modern product made according to new developments in design and construction technology.
