RON DESIGN Articious Co.,Ltd. has completed a thoughtful renovation of a 40 year old reinforced concrete residence, transforming it into a contemporary urban home shaped by travel, culture and modern living. Rather than treating the project as a simple interior refresh, RON DESIGN Articious Co.,Ltd. approached architectural reorganisation and interior design as a single, integrated process, carefully respecting the strength and longevity of the existing structure while adapting it to present day lifestyles and regulations.

The original layout no longer reflected how the clients lived, so RON DESIGN Articious Co.,Ltd. focused on re editing the internal volume to create a richer, more flexible living environment. The concept of living dramatically, as if travelling, guided every decision. Each floor was given a distinct role and atmosphere, allowing movement through the house to feel like a sequence of changing moods rather than a purely functional transition.

A defining element of the renovation is the basement level, reimagined by RON DESIGN Articious Co.,Ltd. as a private adult retreat set apart from the pace of the city. This man cave accommodates both social gatherings and solitary downtime without being fixed to a single use. Sliding partitions connect a media area, bar, bedroom and shower room, allowing the space to adapt fluidly to daily life.

To evoke the feeling of discovering a space while travelling, RON DESIGN Articious Co.,Ltd. introduced wallpaper by British brand Blackpop across walls and textiles. Deep colours and subtle textures add depth and tension without relying on overt decoration. Lighting is deliberately soft and layered, favouring shadow and atmosphere over strong ceiling fixtures, helping the interior calm the senses and restore energy.

Throughout the home, careful attention was given to the relationship between layout, materials, light, textiles and furniture placement. RON DESIGN Articious Co.,Ltd. conceived the interior as an active element that shapes how residents feel, pause and engage with their surroundings. By reinterpreting the constraints of the existing building into a new spatial narrative, RON DESIGN Articious Co.,Ltd. has created an urban home that feels like a journey in itself, defined by balance, depth and lived experience.
