Possibilities of Multi‐family House in Pangyo
Lee Joongwon (professor, Sungkyunkwan University)
Due to its location, the Pangyo residential complex is mostly comprised of large families of three or more members with young children. Designing a multi-household residence that will accommodate families consisting of three or more people on a 70-pyeong lot in Pangyo is a challenging task. It is not all smooth sailing to produce a residence of value that abides by the district unit plan guidance and satisfies the demands of the client.
The multi-household residence in Pangyo can be organized into two categories: vertical partitions and horizontal partitions. Typically, a vertical partition has two households with a basement, ground floor, second floor, and an attic. A horizontal partition has one household occupying the basement and first floor, and the other household on the second floor and attic. K&L Residence chose the horizontal partition type but did not add a basement because of the client’s demand to reduce construction costs.
The client had two other demands. One was to secure privacy and the second was to have two bathrooms and three rooms aside from the living (L)-dining (D)-kitchen (K) spaces. It was a dense programme. The demand for privacy limited this south facing plot to not have a big southerly window. Additionally, the securing of parking space for three vehicles was also a limiting factor.
The site conditions were limiting as well. Typically, house plots in Pangyo are influenced by the shape and type of block. The shape of the site was rectangular - not in a square form which is somewhat more appropriate for designing a multi-household residence. And the block plot was laterally situated on the pedestrian street, so that it was disadvantageous compared to a block plot longitudinally situated which is easier to secure privacy while retaining an open garden. In terms of site conditions, the P House, the architect’s first project in Pangyo, was positive contrast to the K&L House.Therefore, to realise the value of K&L House as a multi-household residence, we have to understand the aforementioned site conditions and the demands of the client.
The architect planned an F-shaped plane (rather than an L-shaped plane often seen on square plots) and located the house on the northwest portion of the site. Designing the house in an F-shape was a reasonable solution to secure parking space for three vehicles and three rooms on the first floor. Yet, the architect did not merely settle on the functional solution provided by the plane. The architect proposed a social solution of installing the entrance of 1st and 2nd floors on a common stairway by setting the house back to the North. It is the point that set the house apart from other residences.
The north portion of the site is more elevated than the south portion. The architect based the ground level of the first floor on the elevation of the north portion. As a result, the first floor slab was elevated from the ground level of the south portion. Four steps up the exterior stairs is the first floor entrance, and four more steps up is the second floor entrance. The exterior stairway became a gathering space for the families of both houses. In addition, the stairway created a deep boundary between common pathway and private building, arguing the significance of the depth in between the common land and private property. This is the first value that K&L House has as a multi-household residence.
