This project is the Seoul flagship store of ST01, located on the ground floor of a commercial building within a cluster of architectural material shops near Hakdong Station. The term “flagship” originates from 17th-century naval terminology, referring to the lead vessel carrying the commanding officer’s flag in battle. Rather than indicating size, it signifies a place that most clearly represents the identity and standards of a brand.
ST01 already operates a large warehouse and exhibition space in the outskirts of Seoul. In this context, the urban store was conceived not as a large showroom but as a place that could most clearly express the brand’s attitude and criteria. Although the space measures only 39 square meters, the intention was to condense ST01’s motto — “Classic stone, nothing else” — into a compact architectural experience. Elements other than stone were deliberately restrained so that the material itself could become the central presence of the space.
Stone exists in an extraordinary range of types and characteristics, including marble, granite, limestone, and quartz. Even within the same type of stone, natural variation ensures that veining and color are never identical. ST01 works closely with the Italian stone company Bagnara and focuses on stones that reveal depth over time rather than those that attract attention through immediate visual spectacle. The brand introduces stones selected through a strict curatorial lens — materials that remain quiet yet distinctive, gradually embedding their presence within a space.
When visiting stone showrooms in the city, several limitations became apparent. Most stores display small samples or reduced slabs instead of full slabs, making it difficult to grasp the material presence that would appear in an actual architectural application. Slabs are often mounted on walls, distancing them from natural light and forcing the material to be viewed primarily under artificial lighting. At the same time, furniture, lighting, flooring, and other interior elements often compete for attention, making it difficult to focus on a single material.
This project began with those observations. Although the site is compact, it faces a relatively quiet two-lane street to the south, allowing the store to take advantage of natural light and outward views. The spatial concept emerged from the storage systems of museum archives, where artworks are mounted on panels and stored on rack systems, retrieved when needed. The act of retrieving and returning works becomes part of the experience itself.
A rail system was installed on the ceiling, from which steel panels measuring 1600 × 2750 mm are suspended to display the stone. The stone slabs are inserted into metal frames in a detail similar to the way glass is installed within glazing frames. This system allows the panels to be detachable while maintaining a scale close to that of a full slab, enabling the physical presence of the material to be experienced more directly.
The panels face the street, allowing the stone to be viewed from multiple distances and angles. From inside the store, visitors can approach the material closely; from outside, the slabs can be observed across the street under natural southern light. The movable panels introduce a subtle sense of movement, enriching the spatial experience.
For stone to remain the protagonist of the space, all other elements needed to recede into the background. The design began by re-reading the existing concrete walls, columns, and beams. These elements were neither clearly symmetrical nor entirely misaligned, but instead existed in an awkward state of near-symmetry, as if resulting from unintended deviations. The first step was to reorganize these elements and establish a new spatial order.
The column at the storefront was clad with the reverse side of Blue Grey stone. This surface, left with traces of oxidation from the cutting process, maintains a tone close to the surrounding concrete while resonating with the weathered metal revealed after the original storefront signage was removed. The column therefore functions as a subtle threshold between the street and the interior.
To address the asymmetry of the ceiling beams, metal fascias measuring 200 mm in height were installed in front of and behind the rail system. This conceals the upper slab and mechanical equipment while allowing shadow to suggest the volume above, giving the space a greater sense of height.
In a small space where every element is immediately visible, strict spatial order becomes essential. The ceiling, walls, and floor all follow a shared 300 mm grid, with vertical relationships carefully aligned. Yet order is perceived more clearly when it includes moments of looseness.
A curved door handle cast in aluminum, along with the Silhouette table and Node stools from Order Matter’s furniture label As Found, introduce this looseness. Their polished surfaces contrast with the matte finishes of the walls and floor, adding a subtle tension and softness to the space.
The floor also follows the same grid logic. Starting from a 150 mm module, it expands into a pattern of 150, 300, 450, 600, and 900 mm increments. Each stone piece was first composed through drawing, after which the outlines were refined in CAD and fabricated using CNC cutting. Irregular stone fragments are placed over the regular grid, allowing order and looseness to coexist.
Remaining stone fragments from the fabrication process were crushed and reused as aggregate within the concrete infill. The resulting floor composition can be understood as a contemporary interpretation of the traditional Italian flooring technique known as palladiana, in which irregular stone pieces are assembled to form a continuous surface.
One of the early references for the project was the small bookstore, The Travel Book Co., from the film Notting Hill. The shop is filled with travel books carefully selected by the owner, and visitors browse the collection while conversing about destinations and stories.
A similar atmosphere was imagined for this store on Nonhyeon-dong’s material street. Visitors who come to select stone engage in conversation with ST01, discussing the character and possibilities of each material.
Meanwhile, a larger warehouse in the outskirts houses a wider range of slabs and selections. In this sense, the urban store functions almost paradoxically as a kind of archive. Selected stones are stored here before continuing their journey — perhaps to the suburban warehouse, or even further to the quarries where they originate.
Rather than a conventional retail showroom, this small flagship store operates as an urban archive where materials selected through ST01’s criteria briefly reside before moving on to their next destination.
