Each time we visited the site, the navigation system unexpectedly guided us through three different routes, allowing us to experience the space from various perspectives. As we approached the existing churches, rice fields, and villages nestled within the valleys of successive mountains, the richness of daily life in the area became evident.

Proportional Church is a historic Protestant Presbyterian church founded in 1954. This small church is situated in a sunlit area surrounded by pine and cypress trees that have stood for decades. While primarily a place of worship, the church also shares a courtyard with the Proportional Village Hall, serving as an inclusive community space where neighbors gather, converse, and relax. The deterioration of the existing chapel and education building led to plans for a new church that integrates a chapel, an education hall, and a parsonage on the current site, previously occupied by a pastor's house and parking lot. The existing church building will be preserved and repurposed for other functions.

The village is centered around the church, with rice paddies and fields. Most homes are single-story farmhouses with gabled roofs. Jibongsan Mountain extends from the west, encircling the site. The village, located in the valley of Jibongsan Mountain, has the church at its heart, with relatively flat farmland stretching to the east and south.

Upon entering the village, about 100 meters ahead, one encounters an older red brick church alongside a newer concrete church. Turning left, a concrete wall marks the boundary of the church. The vertical wall, with its bone-patterned shadows and smooth exposed concrete, creates an inviting gap leading visitors inside.

Following the berm along the concrete wall and path, a doorway emerges, subtly concealed by a solid wall. Above the entrance, a stable concrete eave extends toward the courtyard, seamlessly connecting the indoors and outdoors. The building’s vertical massing contrasts with the tall windows that reveal the interior spaces, visually unifying the three levels.

The church consists of three stacked concrete slabs, supported by robust walls and columns. The different functional areas—the education hall on the ground floor, the chapel on the second floor, and the private residence of the pastor on the third floor—are positioned beneath these heavy concrete plates. Each space interacts with the exterior through varying degrees of openness and enclosure. The horizontally segmented and layered concrete volumes harmonize with the surrounding landscape of flowing mountain ridges and serene rice fields. As the light changes throughout the day, the shifting shadows alter the perception of the building’s volume.

First Floor: A multipurpose space that accommodates religious activities, education, and lectures. The pastor's office, youth room, dining hall, and a small chapel foster communal gatherings. A glass-walled corridor between the youth room and the dining hall visually connects the interior to the courtyard, enhancing communication.
Second Floor: The chapel, where the gable roof of the old church is reflected in the exposed concrete ceiling. Warm wood-tone sound-absorbing panels line the walls. A veranda on the east side offers panoramic views, inviting natural light and enabling visitors to experience the changing seasons indoors.
Third Floor: The private residence of the pastor, designed as a tranquil residence for the pastor and their spouse. A large south-facing window creates a serene atmosphere, where the concrete roof, near and distant landscapes, and vast natural surroundings converge.
