Taking down old buildings yields aged wood, which, after sorting and processing, retains the emotional and intrinsic value of the wood. Preserving its paint and texture, modular furniture for cats is designed while integrating daily necessities for felines. Two sizes of main structures are designed, each with six sides hollowed out, allowing for free interchangeability of upper and lower shelves, surrounding door panels, and stackable cabinets to create different living scenarios.
The door panels are designed using window slide tracks for easy assembly and disassembly, catering to cats' natural hiding instincts. Incorporating glass creates a semi-transparent feel, satisfying both human curiosity about observing cats and cats' curiosity about the outside world through the glass.
The shelves are divided into old wood and perforated boards. Two different sizes of old wood shelves are designed, allowing for planning of cat activity routes according to needs. Perforated boards are accompanied by accessories, allowing for different combinations according to various living scenarios.
A harmonious day in the life of humans and cats is achieved through the versatile modular cat cabinet, creating daily living scenarios.
In line with the principle of environmental sustainability, the Earth-friendly day is celebrated through resource-conscious design.
Trees originate from nature, while old wood originates from life. By recycling and reusing old wood, its new appearance is continued in life, accompanying us like a good day every day. Enjoying life, savoring the changes in things and the environment, and fully immersing ourselves in and returning to life
