1. Legal Definition of Building Relocation

According to the Building Control Act, B.E. 2522 (and its amendments), "building relocation" means moving a building or parts of a building from its original site to a new site, or moving a building to a different position on its original site. For example:

• Moving a building to a new plot of land: Such as moving an entire old wooden house to be reconstructed on another plot of land.
• Moving a building to a new position on the same plot of land, Such as moving a house to the front or back of the original property.
• Moving a building across public roads or through public areas: This is the most complex and restrictive case.

Important Note:

• Building relocation often involves buildings with less complex structures or old buildings with architectural value that are intended for preservation.
• This process is different from demolition and new construction because it preserves the main structure of the building.

2. Directly Related Laws and Regulations

Building relocation is subject to the provisions of the following laws:

• Building Control Act, B.E. 2522 (and its amendments): The primary law governing building relocation.
• Ministerial Regulations issued under the Building Control Act: Covering technical details and standards related to relocation, such as the structural stability of the building during the move.
• Comprehensive Urban Planning Law (by location): The new location of the relocated building must comply with the land use regulations of the comprehensive plan in that area (e.g., land use type, FAR, OSR, setbacks).
• Laws concerning Highways/Public Roads: If the relocation must pass through public roads, a permit must be obtained from the agency responsible for that road (e.g., Department of Highways, Department of Rural Roads, Bangkok Metropolitan Administration, Municipality). There may also be regulations on size, height, and time of relocation.
• Laws and Regulations of Public Utility Agencies: Such as the electricity, waterworks, and telephone authorities, if the building relocation involves cutting/moving power lines, telephone lines, or water pipes.

3. The Process of Applying for a Building Relocation Permit

The general process for applying for a building relocation permit involves the following sequence of steps:

3.1 Assess Feasibility and Preliminary Planning:

  • Civil Engineer: Responsible for the design and calculation of the relocation method and related structures, along with a copy of their professional license and proof of membership in the professional council.
• Proof of Ownership of the Building (if the building and land have different owners).
• Photographs of the current building (before relocation).

5. Approximate Processing Time and Fees

• Processing Time: Building relocation is a complex process. The review may take a considerable amount of time, from 60 working days upwards, depending on the complexity of the project and the number of agencies involved.
• Fees: Calculated based on the area of the relocated building, according to rates specified in the ministerial regulations.

6. Precautions and Things to Know Before Deciding to Relocate a Building

• Complexity and High Cost: Building relocation is highly complex, requires specialists and specialized equipment, making it very expensive compared to demolition and new construction.
• Risk to the Building's Structure: The building may be damaged during relocation if not planned and executed with extreme care.
• Impact on the Public and Neighbors: Building relocation can cause traffic congestion, noise, dust, or disruption to public utilities. The public and neighbors should be notified in advance.
• Size and Route Limitations: Large or intricately shaped buildings may be difficult to move or may be limited by the route (e.g., road width, bridges, power lines).
• Permits from Multiple Agencies: If the relocation involves public roads or utilities, coordination with and permits from multiple agencies will be required.
• Economic Feasibility: You should carefully consider whether relocating the building is economically viable compared to demolishing and building anew.

7. Scenario Example: The Great Journey of "Grandma's House"

• Khun Ploy: A young designer who is deeply attached to her grandmother's old wooden house.
• Grandma's House: An 80-year-old traditional teak house located on a piece of land in the city center that the family has decided to sell.

The Beginning: A Dream to Preserve a Memory

When her family decided to sell the land in the city center, Khun Ploy was saddened by the thought of losing her grandmother's house, which was full of memories and architectural value. She then had a dream to "relocate the building" to a new plot of land she owned by the river, to renovate it into a small café and gallery.

Step 1: Facing Reality (Assessment and Planning)

Khun Ploy began by contacting a company specializing in building relocation. The expert came to survey and explained the immense challenges:

• Building Condition Assessment: A structural engineer had to thoroughly assess whether the old wooden structure was strong enough to withstand being lifted and moved, and how to design the temporary reinforcement.
• Route Survey: The team had to survey the map and relocation route from the city to the riverside land in detail, checking for all obstacles such as the height of pedestrian bridges, the location of high-voltage power lines, and the width of the road at each segment.
• Complex Permitting: The expert informed her, "This isn't a single permit process; it requires coordination with many agencies."

Step 2: The Journey Through the Law (Applying for Permits)

After deciding to proceed, Khun Ploy hired a full professional team and began the permit application process, which took several months:

• Submitting to Local Officials: Applied (Form Khor 1) for "Building Relocation" to the District Office at the original location and to the SAO at the new location.
• Submitting to Road Authorities: Submitted a request to use the route to the Department of Highways and the Department of Rural Roads.
• Coordinating with Utilities: Sent letters to the Electricity Authority and Communications Authority to request cooperation in temporarily moving or cutting power and communication lines on the day of the move.

Step 3: The Historic Moving Day

After receiving all the necessary permits, the relocation of Grandma's House began at night to minimize traffic impact. The sight of the entire wooden house being lifted onto a special truck and slowly moving down the street, under the supervision of engineers and traffic police, was truly spectacular.

The Result:

"Grandma's House" arrived safely at its riverside destination and was installed on a new, strong foundation. Months later, the place became a famous café that perfectly preserved the beauty of the past.

Conclusion from the Scenario: Khun Ploy's story shows that building relocation is a massive and complex project. Success depends not only on technology but also on meticulous planning, respect for the law, and professional coordination with all sectors, allowing a precious heritage to begin a new life in a new place.

8. Conclusion

In summary, applying for a building relocation permit is considered the most complex and challenging process among all building-related permit applications, as it involves advanced engineering, detailed logistical planning, and, most importantly, the coordination with and application for permits from multiple government sectors simultaneously. The success of this great mission, therefore, depends not only on the strength of the building itself but on having an expert consultant who acts like an orchestra conductor, capable of planning and coordinating all elements to proceed in unison and without obstacles.
