Furniture should prioritize smart integrated types, such as desks with attached storage or modular filing cabinets. However, a common drawback of open design is often noise from the surrounding space, so businesses should incorporate carpets, sound-absorbing ceilings, felt partitions, or greenery to create a quieter and more comfortable working environment.

Office Design by Function
An effective office starts with designing based on the function of each area. The reception space needs to be friendly and professional, the work area must ensure concentration, meeting rooms focus on connectivity and exchange, and the entertainment/rest area provides relaxation. When each space is designed “correctly for its function and role,” the office will not only be beautiful but also operate smoothly and optimize productivity.
Executive Office Design
Rooms for the executive board do not need to be overly large, but this space should be separate from the common work area to ensure quietness and privacy, while utilizing a position near the window to capture natural light, creating an airy and luxurious feeling. Furniture should include an executive desk, filing cabinets, and small reception sofas, using high-end industrial wood materials or combining glass, marble,… to enhance the modern look and represent the business.

Work Area
This is the area that occupies the most space. For a 400m2 office area, you should choose modular desks to save space and create synchronization. The aisles between desk rows need to be wide enough for convenient movement, while ensuring the lighting system utilizes both external light and LED light to keep the workspace bright and enhance concentration. Furthermore, a common mistake is designing without considering acoustics, so when designing, you should use carpets, sound-absorbing ceilings, and felt partitions to reduce noise.
Pantry Design
The pantry in a 400m2 office is typically about 20 to 30m2, and though not large, it plays a vital role in creating a resting space and fostering employee connection. When designing, you need to consider noise and odor issues; a separate ventilation and odor extraction system is necessary to prevent them from spreading to the work area. The pantry should be located near the employee area for easy access, but avoid placing it right in the main aisle or next to meeting rooms/executive offices to maintain professionalism. For aesthetics, use bright colors, warm lighting, and consider adding high tables/chairs or small sofas to create a relaxed feeling, encouraging interaction between departments.
Meeting Room Space
A common mistake when designing meeting rooms is investing too much area in large, infrequently used rooms, while small meeting rooms are always overloaded. Therefore, practical consideration is needed for reasonable allocation. Meeting rooms also need good sound insulation, fully equipped with devices like large screens, microphones, and cameras to serve online meetings. Regarding lighting, businesses should choose neutral light to help everyone focus more, and arrange glass doors combined with curtains to both utilize natural light and allow flexibility when privacy is needed.
Reception Area
**Reception counter design** should harmonize with the office’s overall style, combining luxurious materials such as wood, stone, glass, or metal to increase professionalism. The lighting system needs to be arranged subtly, perhaps using recessed lights or decorative lights to create accents. Behind the reception counter, there should be a prominent logo or brand sign, helping customers easily recognize the brand. Additionally, greenery, a waiting area with comfortable seating, and small tables can be arranged to create a friendly, comfortable feeling for visitors during transactions.
Things to Note When Starting to Design a 400m2 Office
When designing an office with an area of 400m2, the first important thing is to clearly understand the usage goals and the business’s operating model. From there, the arrangement of space, the selection of furniture, or the layout of functional areas will truly be suitable and effective. Let’s immediately refer to the important notes from COIDB when designing a professional, high-class 400m2 office!
Optimizing Functionality According to Business Model
Each business will have different structures and operational needs. For example, businesses focused on internal operations will need space for teamwork and extensive storage systems, while companies that frequently host guests prioritize luxurious reception and meeting areas. Optimizing functionality means arranging the space so that each department has a tight connection, while still ensuring privacy and work efficiency. Furthermore, it is necessary to allocate area appropriately to avoid waste or lack of space for each department.
Designing Flexible Space
When designing a 400m2 office, flexibility is the factor that helps the office easily adapt to changing needs in the future. Therefore, businesses should prioritize using mobile partitions, easily movable tables and chairs, and multi-functional areas such as spaces that can serve as both a meeting room and a place for presentations or small workshops. These designs help businesses save restructuring costs when expanding personnel or changing operational models. Additionally, flexibility creates conditions for the space to always be renewed, preventing boredom for employees.
Storage System and Lighting Arrangement
Despite the large area, if there is no rational storage system, the office will quickly become cluttered and lack professionalism. Prioritize designs with built-in cabinets, open shelves, or storage modules integrated with desks to save space while remaining tidy.
Moreover, lighting is an indispensable element; a harmonious combination of natural light and lighting systems should be used. The main work area should use neutral white light, while the relaxation and reception areas can use warm yellow light to create a cozy feeling. Appropriate light arrangement not only helps reduce eye strain but also contributes to enhancing the aesthetic appeal of the entire space.
Feng Shui Factor
In 400m2 office design, feng shui plays an important role in creating harmony and bringing positive energy. Pathways should be arranged to be airy, avoiding placing desks with backs facing the door or directly opposite the entrance to limit negative energy flow. The executive area should be placed in a position with its back against the wall, having a comprehensive view of the entire space, combined with natural light to create vitality, helping employees work more effectively.
Expressing Brand Identity
Clearly expressing brand identity will create a strong impression in the eyes of customers and partners. Therefore, the company logo should be placed in easily visible locations such as the reception area or the main wall of the meeting room. At the same time, the color, material, and style of the office furniture need to be synchronized with the brand identity kit.
The office is where a business can paint its own picture with brand colors, cultural lines, and creative touches.
