FAQ’s
Frequently Asked Questions
What is the minimum budget required to build a house?
The budget depends on several factors, including the size of the house, materials used, and location.
On average, construction starts from approximately THB 2–3 million for a standard home built on a 50 sq.w. plot in suburban Bangkok, using standard materials.
Where do I apply for a construction permit, and what documents are required?
As of 2026, construction permits can be submitted online via the BMA OSS system (for buildings not exceeding 2,000 sq.m. and 5 floors).
If all documents are complete and approved, results are typically issued within 14 days.
For submissions through local administrative offices (Subdistrict Administrative Organization, Municipality, or District Office), the process takes up to 45 days, provided all documents are correct and no revisions are required.
Required documents include:
- Architectural and Engineering Drawings (Complete Set)
- Architectural, structural, electrical, and plumbing plans
- Signed by licensed architects and engineers
- Architectural, structural, electrical, and plumbing plans
- Copy of Land Title Deed (Nor Sor 4 or equivalent)
- Certified true copy
- All pages must be included
- Certified true copy
- Letter of Consent for Construction (if the landowner is not the applicant)
- Along with a copy of the landowner’s ID
- Along with a copy of the landowner’s ID

- Available at district offices or via the BMA online system
How long does it take to build a house?
Construction time depends on the size and complexity of the project.
For example, a typical 2-storey house takes approximately 10–12 months to complete.
How are contractor fees calculated?
Contractors typically charge either per square meter or as a lump-sum contract.
As of 2025, the average cost for reinforced concrete residential construction is around
THB 22,000 – 30,000 per sq.m., depending on material specifications.
How can I determine if a contractor is reliable?
Review their past projects, ensure a formal contract is in place, and confirm that work stages and payment schedules are clearly defined.
Which materials are worth investing in?
Key areas that should prioritize higher-quality materials include:
- Structural components
- Electrical and plumbing systems
- Thermal insulation materials
Planning ahead for solar panels or smart home systems is also recommended, as it is more cost-effective than retrofitting later.
Is it required to have an engineer or architect supervise the project?
Yes. By law, qualified professionals must supervise construction.
For example:
- Structural engineers must approve load calculations for columns and beams
- Electrical engineers must oversee electrical system installations
How can I prevent budget overruns?
Develop detailed plans and use contracts that clearly specify materials.
A reliable contractor will provide a complete breakdown, including models, specifications, quantities, and installation costs (e.g., brand, model, unit price, installation fee).
This allows homeowners to review and adjust materials before construction begins, ensuring the project stays within budget.
Is construction insurance necessary?
It is not mandatory but highly recommended, as it protects against potential damage during construction.
If financing is obtained through a bank, insurance (such as fire insurance) is typically required and included in the loan.
What is the standard warranty period after construction?
Typically:
- Structural work: 5–10 years
- General work: 2–3 years
