Vietnam: What is the net building density of land plots for the construction of factories in Vietnam? What is the maximum gross building density?
What is building density in Vietnam?
Under Subsection 1.4.20 Section 1.4 Vietnam Standard QCVN 01:2021/BXD promulgated together with Circular 01/2021/TT-BXD:
Building density
- Net building density: refers to total area of primary constructions over a land plot (excluding area of outdoor constructions such as decorations, swimming pools, parking lots, parking spaces, sports yards, guard posts, passages heading up, passages heading down, sheltered ventilation mechanisms of basements, and other technical infrastructural constructions).
NOTE: Structural components and architectural details such as: gutters, porticos, canopies, steps, window-sill, bridge passages already complying with fire safety requirements may not be included in total area costs if said structural components and architectural details do not obstruct movement of humans, vehicles, and do not combine with other use purposes.
- Gross building density: refers to land occupancy ratio of primary structures on a land plot (which may include: yards, roads, trees, open spaces and areas where structures are not constructed).
Thus, net building density and gross building density are specified as above.
What is the net building density of land plots for the construction of factories in Vietnam?
Under Subsection 2.5.3 Section 2.5 Vietnam Standard QCVN 01:2021/BXD promulgated together with Circular 01/2021/TT-BXD:
"2.5 Requirements for industrial parks, export-processing zones, and hi-tech zones
2.5.3 Land use
- Land for construction of industrial parks, export-processing zones and hi-tech zones must be planned depending on industrial and socio-economic development potentials and relevant development strategies of each local government;
- Ratio of land types in industrial parks, export-processing zones, and hi-tech zones depends on form and nature of manufacturing facilities and areas of land plots for construction of manufacturing facilities and storage facilities but must also conform to Schedule 2.6;
- Maximum net building density of land plot for construction of factories and storage facilities is 70%. Maximum net building density of land plots for construction of factories with more than 5 stations for manufacturing is 60%.
Thus, the maximum net building density of land plots for the construction of factories and storage facilities is 70%. The maximum net building density of land plots for the construction of factories with more than 5 stations for manufacturing is 60%.
What is the maximum net building density in Vietnam?
Under Subsection 2.6.3 Section 2.6 Vietnam Standard QCVN 01:2021/BXD promulgated together with Circular 01/2021/TT-BXD stipulating the maximum net building density:
"2.6. Requirements for scenery, urban design, and building layout in new development areas
...
2.6.3 Maximum net building density
- Maximum net building density of land plots for construction of freestanding houses shall be specified under Schedule 2.8;
- Maximum net building density of land plots for construction of apartments shall be identified under urban planning and design schemes but must conform to Schedule 2.9 and satisfy requirements for minimum distance between building blocks under 2.6.1 and structure clearance under 2.6.2;
- Maximum net building density of land plots for construction of service – public structures such as education, medical, culture, sports facilities and markets in new construction areas is 40%;
- Maximum net building density of land plots for commerce and services or multi-purposes shall be specified under urban planning and design schemes but must conform to Schedule 2.10 and satisfy requirements for minimum distance between building blocks under Section 2.6.1 and structure clearance Section 2.6.2;
Thus, the maximum net building density is specified as above.
What is the maximum gross building density in Vietnam?
Under Subsection 2.6.4 Section 2.6 Vietnam Standard QCVN 01:2021/BXD promulgated together with Circular 01/2021/TT-BXD stipulating the maximum gross building density:
"2.6. Requirements for scenery, urban design, and building layout in new development areas
...
2.6.4 Gross building density
- Maximum gross building density of residence-related unit is 60%;
- Maximum gross building density of tourist resorts is 25%;
- Maximum gross building density of parks is 5%;
- Maximum gross building density of theme parks is 25%;
- Maximum gross building density of specialized theme greens (including golf courses) and natural environmental protection zones shall be prescribed based on functions and relevant regulations but no more than 5%.
Thus, the gross building density in Vietnam is specified as above.
