【Preparation before opening a restaurant to reduce operational risks】
There are numerous preparations required before opening a restaurant or eatery in Hong Kong. Not only must you balance aesthetics with practicality in interior design, but you must also strictly adhere to government statutory requirements across five key areas: "Air, Fire, Water, Electricity, and Gas." These regulations are not just about operational safety; they directly impact customer experience and environmental sustainability. From planning ventilation systems to configuring energy equipment, every detail must be carefully considered in compliance with legal requirements. By skillfully blending functionality with spatial ambiance through design, one can create a compliant and attractive dining space.
Air - Ventilation Systems for Restaurants and Eateries
The design of a restaurant's ventilation system is a primary focus of government regulation. In accordance with the Air Pollution Control Ordinance and the Food Business Regulation, catering premises must install mechanical ventilation equipment that meets established standards to ensure kitchen fumes and odors are effectively exhausted while maintaining indoor air circulation. Design planning requires calculating the space's capacity and the heat generated by cooking equipment to configure exhaust fans and fresh air supply systems with appropriate airflow. Furthermore, an air pressure gradient must be established between the dining area and the kitchen to prevent the spread of fumes to customer areas. Exhaust ducts must be made of fire-resistant materials and cleaned regularly to comply with fire safety regulations. Some high-end restaurants integrate air purification devices and smart sensors to monitor CO2 and suspended particulate concentrations in real-time, enhancing environmental comfort beyond regulatory minimums. Interior designers often conceal vents within ceiling features or decorative grilles to meet functional needs while maintaining the integrity of the spatial aesthetics.
Fire - Fire Safety Specifications for Restaurants and Eateries
Fire safety is a core requirement in the design of dining spaces. Under the Fire Services Ordinance, restaurants must be equipped with a sufficient number of fire extinguishers, automatic sprinkler systems, and emergency lighting. Escape route widths must conform to per-capita area ratios, and fire-resistant building materials must be used for compartmentation. As a high-risk zone, the kitchen must be isolated from other areas by fire walls with a fire-resistance rating of at least two hours, and cooking ranges must be fitted with automatic fire suppression systems and heat-sensing alarms. Designers often treat wooden decorative surfaces with fire-retardant coatings or use Grade A fire-resistant materials, such as mineral wool boards, for partitions. They also integrate fire equipment into the overall visual design, such as embedding emergency exit signs into artistic lighting fixtures or concealing fire extinguishers behind integrated panels. The trend of open-plan kitchens tests design expertise, requiring precise calculations for fire-rated glass partitions and smoke control systems to strike a balance between regulatory compliance and visual transparency.
Water - Water Supply and Drainage Networks for Restaurants and Eateries
The planning of plumbing and drainage systems directly impacts hygiene ratings and environmental compliance. According to the Water Pollution Control Ordinance, restaurants must install grease traps to treat kitchen wastewater, and pipe gradients and diameters must be professionally calculated to prevent blockages. The Food and Environmental Hygiene Department (FEHD) specifically mandates the number and location of sinks; for instance, a separate handwashing sink must be provided in food preparation areas, clearly distinct from dishwashing sinks. Designers often use stainless steel for waterproof countertops and walls, applying anti-mold sealant at joints while concealing drainage trenches under non-slip floor tiles. High-end restaurants may introduce water recycling systems to filter wash water for irrigation, fulfilling environmental regulations while fostering an ecological image. Recently, incorporating water features into designs—such as entry-way water curtains or small indoor fountains—has become popular, though these require additional waterproofing layers and independent drainage lines to avoid compromising structural safety.
Electricity - Power Supply Systems for Restaurants and Eateries
The configuration of power systems must strictly comply with the Electricity Ordinance and guidelines from the Electrical and Mechanical Services Department (EMSD). Kitchen equipment must utilize independent circuits equipped with residual current circuit breakers (RCCBs), and socket locations must be situated away from water sources at ergonomic heights. Crucially, the total electrical load must be assessed to ensure the restaurant can handle all appliances operating simultaneously, as there is a significant difference in capacity between single-phase and three-phase supplies. Smart energy-saving systems have become a trend; sensors can control air conditioning and lighting, which not only meets energy efficiency requirements under the Buildings Energy Efficiency Ordinance but also reduces operating costs. Interior designers often conceal distribution boards within custom cabinetry or artistic installations, using anti-glare lighting paired with linear LED strips to meet illuminance standards while creating layered light effects. High-load equipment like induction cookers and ovens requires dedicated ventilation paths to prevent circuit overload and associated hazards.
Gas - Gas Supply Systems for Restaurants and Eateries
If a restaurant does not use open flames, gas is not a critical factor in opening the eatery; otherwise, the safety management of the gas system remains a focus of government inspections. Under the Gas Safety Ordinance, all gas pipelines must be installed by registered contractors and fitted with gas leak detectors and automatic shut-off devices. Kitchens must maintain an air change rate of at least 0.5 times per minute, and gas appliances must be placed at least 1.5 meters away from combustible materials. Designers typically house gas meters in dedicated, well-ventilated compartments and cover gas pipelines with explosion-proof materials. Modern restaurants tend to adopt smart gas monitoring systems that allow real-time display of gas concentrations and equipment status via mobile applications, while integrating exhaust pipes within structural columns to maintain a clean aesthetic while meeting safety codes. Some owners even reserve space for piping to facilitate a future transition to clean energy sources like induction cooking, demonstrating a commitment to sustainability.
Design House HK Restaurant Decoration and Design Services
From the invisible aesthetics of ventilation ducts to the artistic integration of fire safety equipment, Hong Kong restaurant design is constantly pushing past regulatory frameworks and creative boundaries. A professional design team must be well-versed in the requirements for restaurant licensing. On the premise of ensuring compliance, safety, and hygiene, they must use material combinations and light manipulation to craft a unique dining experience. With over 10 years of experience, the Design House HK interior design team can provide professional advice for everything from cozy cafes to stylish restaurants. We provide close supervision of the renovation and construction team to ensure that the project schedule remains under control.
