A chic slate facade for an international fashion store in Korea

COS is a global contemporary fashion brand. When they were designing the new shop in the centre of Seoul, they had one thing crystal clear: the store should have an innovative image to meet the expectations of the brand’s clients.

COS Korea had an image in mind and suggested RnK Design architectural study a new cladding material for the exterior-wall renovation. The architect who oversaw the project had no idea that slate was going to be the perfect solution for his needs, as before this project, the concept of slate rainscreen cladding didn’t exist in Korea.

The architect found our partner Slate Korea’s blog and they collaborated to design the new store. They worked hard and had many meetings to overcome the huge challenge of developing the slate rainscreen cladding concept in Korea.

COS and the architect chose a square pattern to give a touch of modernity. The final choice was 25×20 format rectangle slate with 5cm overlap to create the 20×20 square design. Every corner except front side was metal flashed, because the client was looking for something that “looks-like thick stone wall” without metal flashing like other COS flagship stores.

After 2 years, COS store became the most important example of a slate building in Korea and it has still the same appearance today, without changes in color. The modern square format design and the beautiful shiny CUPA slate tiles became the ‘slate wall-cladding standard’ in Korea.

Following the CUPA COS project, there have been many inquiries from architects and end-users. This beautiful building has enabled me to explain about ‘CUPA slate & its wall-cladding’ with confidence.  Consequently, resulting in more slate wall-cladding projects, states Jihoon Kim, Slate Korea’s owner.

Since then, Slate Korea has participated in more projects and tested more wall-cladding application with bigger and thicker slates. Nevertheless, CUPA COS project was the first to create and develop natural slate wall-cladding in Korea.
