Urban Planning in Thailand
Urban planning laws in Thailand exist to designate the overall land use areas of the country, defining the use of each type of land to ensure a good quality of life for everyone. These include provisions for utilities and public facilities in each area to support the future development of those cities. Without urban planning laws, problems such as slums, air pollution, or a lack of agricultural land would arise. The laws specify what can be built in each area, what is prohibited, or what can be built with height restrictions.01 Types of Zone
There are many color-coded categories used to designate different areas in Thailand as follows:
1. Yellow Zone
- Low-Density Residential AreaAreas primarily for residential use with low-density housing are typically located in the suburbs. These zones are designated to promote, support, and develop a good living environment, as well as to support the expansion of housing in the suburbs by providing a better environment and public transportation services.
2. Orange Zone
- Moderate-Density Residential AreaAreas primarily for residential use with medium density are located adjacent to inner-city zones. Housing can be built similarly to yellow zones. These zones are designated to support residential living and the expansion of housing adjacent to inner-city areas, suburban community centers, industrial zones, industrial estates, and public transportation services. However, animal shelters cannot be established because the noise from animals would disturb the community.
3. Brown Zone
- High-Density Residential AreaHigh-density residential areas are zones with a large population, located in the inner city of Bangkok or business districts, and are considered high-value land. The brown zones are primarily intended to accommodate residential living within public transportation service areas, including the transition zones between the inner city and business districts. Therefore, brown zones allow land use for purposes such as factories or various establishments, but this usage is limited to no more than 10% of the area. This is because these zones are more suitable for residential purposes, including houses, townhouses, condominiums, and large apartment complexes.
4. Red Zone
- Commercial AreaThe red zone area focuses on industrial business and commercial activities, ranging from community to regional levels. These zones are designated to utilize land for business centers, commerce, services, and tourism to provide convenience for the public, including the construction of various types of residences and government facilities. However, there are limitations to using a maximum of 25% of the total area for building other types such as industrial factories, fuel depots, animal farms, cemeteries, transportation hubs, and waste disposal facilities. This limitation is to mitigate potential risks to residents’ living conditions and community health issues.
5. Pink Zone
- Community AreaThis land use type is designated for a variety of purposes, including residential, commercial, agricultural, educational, religious, government, and utilities and public infrastructure.
6. Purple Zone
- Industrial & Warehouse AreaThis area is ideally suited for industrial purposes because it allows factories, warehouses, and manufacturing facilities to be built across all areas without any restrictions. Additionally, residential buildings such as houses, dormitories, small-sized condominiums, and shops can be constructed. Furthermore, the purple zones also support subcategories such as hotels, cemeteries, hospitals, and educational institutions. However, tall buildings and large condominiums cannot be built in purple zones unless they are part of a factory.
7. Light Purple Zone
- Specific Industries AreaThis area is specifically designated for warehouses, acting as a regional logistics hub for Southeast Asia with a robust transportation system. Light purple zones on city plans prioritize cargo storage and assembly without manufacturing, minimizing environmental impact and community disruption. Notably, similar to purple zones, they allow residential development like houses, dormitories, small condominiums, and shops, but restrict the construction of tall buildings and large condominiums.
8. Light Purple with White Dot Zone
- Industrial Development AreaThis land use type is designated for industrial development, supporting areas adjacent to special economic zones for targeted industries or related to manufacturing, service industries, and warehousing.
9. Green Zone
- Rural & Agricultural AreaThis area is suitable for agriculture or related activities, forests, and conservation lands to protect natural resources and biodiversity. It also allows land to be divided into small plots for residential or public utility purposes. However, green zones cannot be used to construct fuel depots, oil refineries, and other factories.
10. White with Green Diagonal Stripes Zone
- Rural & Agricultural Conservation ZoneThis type of land is utilized for agriculture or related agricultural activities, as well as government facilities. There is a strong emphasis on the conservation and management of agricultural areas to preserve the environment. Other permitted uses are limited to no more than 5% and 10% respectively.
11. Light Green Zone
- Recreation & Environment Conservation AreaZones designated for recreational purposes, including parks, sports fields, and public gardens.
12. Light Brow Zone
- Thai Art & Cultural Conservation AreaThis light brown zoning designation encompasses the inner Bangkok area of Rattanakosin Island. It prioritizes land use for the conservation and promotion of Thai cultural heritage, commercial activities, tourism within conservation zones, government offices, and critical public infrastructure. Consequently, dormitories are prohibited in light brown zones, and only hotels are permitted. Additionally, buildings must adhere to height and size restrictions.
13. Blue Zone
- Governmental Institutions, Public Utilities & Amenities AreaThe blue area is government land, encompassing all areas in the city plan designated for public use only: government facilities, educational institutions, temples, hospitals, schools, and transportation hubs, public utilities, and public services, to benefit the community collectively.
In summary, similar shades often indicate the same type of land use. For example, purple zones designate industrial and warehouse areas, while red signifies commercial use. Orange and yellow shades typically refer to residential areas. Blue zones represent government agencies and state-owned land, and green zones denote agricultural areas and conservation. Additionally, specific colors may indicate specialized land use areas.You can check from the comprehensive city plan of the province or the specific city plan of the municipality, which will show detailed maps of land color zones.
