AC Concept office is a work place for interior design. An office has been used for over 10 years with traditional office desks and partitions. With the spread of COVID-19, there are new expectations about flexibility, working conditions and life balance. The office was redesigned and renovated in 2020. The goal of this project is to provide a safe, relax and flexible working place for the staff. This is a place where people can work hard, dream, have fun and get inspiration. To encourage interaction and teamwork, an open- plan environment was adopted. By removing the wall, transitional work partitions and office desks, the office space was redesigned and divided into different functional and comfortable area, including reception, work area, fun area, kitchen and a meeting room. Work Area was designed like a dining room while the Fun Area was designed like a living room. The large table in the Work Area is adjustable. It could also be used as work table or dining table for the lunch meeting. The custom made display cabinet was a multi-function cabinet with sliding doors. When the sliding doors were closed, it was a display cabinet with various art collections. When the sliding doors were opened, television inside could be used for presentation. Without any partitions, staffs were free to use the work place. Lighting has deep impact on our mood, emotion and productivity. Different mood and tones with lighting had been preset in different area. With comprehensive intelligent and Wi-Fi system, staff could control the lighting, air-conditioning, and sound system, curtain and sliding door easily by simply using smart phone or voice command. To encourage easy interaction, an open-space kitchen was adopted. Different flooring materials were used in Work Area and Kitchen. A custom made island with lighting and ceramic countertop was designed as a multi-purpose table where staff can cook, prepare food, eat, play or even work. Wireless charger, ventilator and cooking stove were built in the table. The Multi-function Meeting room could be a space for internal meeting, conference call and online meeting. Glass sliding door separates the Meeting room and Work Area to balance the needs of interaction and privacy. It allowed staff to freely collaborate without the worry of disturbing others.
